4676f63d4c korina: do schedule napi after testing for it
The called netif_rx_schedule() does all the work for us:
- it checks the return value of netif_rx_schedule_prep() and
- if everything is ok calls __netif_rx_schedule().
Before this change, the driver received absolutely nothing.

4cf83b664f korina: rework korina_rx() for use with napi
This function needs an early exit condition to function properly, or
else caller assumes napi workload wasn't enough to handle all received

a13b27826a korina: reset resource buffer size to 1536
The new value is the one used in the external patch before and allows at
least a standard MTU of 1500 to be handled correctly. Impact of this
change gets visible when bigger packets are to be received, issuing:
| ping -s 492 <IP>
and bigger payload sized led to 100% packet loss.

b96ecfa689 korina: fix usage of driver_data
Using platform_set_drvdata() here makes no sense, since the driver_data
field has already been filled with valuable data (i.e. the MAC address).
Also having driver_data point to the net_device is rather pointless
since struct korina_device contains an apropriate field for it.

1cf167f27a bnx2x: Using singlethread work queue
Since slow-path events, including link update, are handled in
work-queue, a race condition was introduced in the self-test that
sometimes caused the link status to fail: the self-test was running
under RTNL lock, and if the link-watch was scheduled it stoped the
shared work-queue (waiting for the RTNL lock) and so the link update
event was not handled until the self-test ended (releasing the RTNL
lock) with failure (since the link status was not updated)

cbbe1efa49 IPoIB: Fix deadlock between ipoib_open() and child interface create
Fix a deadlock between child interface creation/deletion and ipoib
start/stop.  The former takes vlan_mutex, and then might take RTNL via
register_netdev()/unregister_netdev().  The latter is executed with
RTNL held, and tries to take vlan_mutex, which can lead to an AB-BA
deadlock.

Fix this by having the child interface creation/deletion code take the
RTNL first so vlan_mutex always nests inside RTNL.  We can use
register_netdevice() for child interfaces because we form the
interface name from the parent interface and hence don't need the '%'
expansion of register_netdev().

937f1ba56b net: Add init_dummy_netdev() and fix EMAC driver using it
This adds an init_dummy_netdev() function that gets a network device
structure (allocation and lifetime entirely under caller's control) and
initialize the minimum amount of fields so it can be used to schedule
NAPI polls without registering a full blown interface. This is to be
used by drivers that need to tie several hardware interfaces to a single
NAPI poll scheduler due to HW limitations.

It also updates the ibm_newemac driver to use that, this fixing the
oops on 2.6.29 due to passing NULL as "dev" to netif_napi_add()

Symbol is exported GPL only a I don't think we want binary drivers doing
that sort of acrobatics (if we want them at all).

d1d5e6b1ce sis900: generate fake MAC address if the hardware doesn't have one
The attached patch modifies the sis900 driver when the MAC address
read from the hardware is invalid. As suggested, the patch now
generates a random address so that the user can go on and use
the hardware. In any case a message is also shown to warn on the
unexpected condition.
This seems to happen with newer HW implementation of the sis900
chipset, since this never came up before.

Patch is against vanilla 2.6.28 (but the driver doesn't change so often,
so it will probably apply to older/newer versions too).

See bugzilla ID 10201 and 11649 and ignore the previous patch.

Freescale on-chip TBI PHYs reports PHY ID as 0x0, but as of

    phy: fix phy address bug

    PHYID returns 0xffff and not 0xffffffff when not found and in some
    case(at91sam9263) 0x0. Maybe this patch could be useful.

phy_device.c treats PHY ID == 0x0 as bogus IDs, and that results in
gianfar driver failure to see the TBI PHYs. This code snippet triggers:

	if (!priv->tbiphy) {
		printk(KERN_WARNING "SGMII mode requires that the device "
				"tree specify a tbi-handle\n");
		return;
	}

Although tbi-handle is specified in the device tree.

Btw, technically PHY ID == 0x0 is a valid ID (if we ever see a PHY
manufactured by Xerox :-).

125c97d8a5 fix early_serial_setup() regression
Commit b430428a18 ("8250: Don't clobber
spinlocks.") introduced a regression on the parisc architecture, which
broke the handover to the serial port at boottime.

early_serial_setup() was changed to only copy a subset of the uart_port
fields, and sadly the "type" and "line" fields were forgotten and thus
the serial port was not initialized and could not be used for a
handover.  This patch fixes this by copying the missing fields.

As this change to early_serial_setup() doesn't need an initialized
spinlock in the uart_port struct any longer, we can drop the spinlock
initialization in the superio driver.

32aeef605a [SCSI] Skip deleted devices in __scsi_device_lookup_by_target()
__scsi_device_lookup_by_target() will always return
the first sdev with a matching LUN, regardless of
the state. However, when this sdev is in SDEV_DEL
scsi_device_lookup_by_target() will ignore this
device and so any valid device on the list after
the deleted device will never be found.
So we have to modify __scsi_device_lookup_by_target()
to skip any device in SDEV_DEL.

introduced usage of IDR functionality but broke userspace side.

Before this commits it was possible to allocate new ppp interface with
specified number. Now it fails with EINVAL.  Fix it by trying to
allocate interface with specified unit number and return EEXIST if
fail which allow pppd to ask us to allocate new unit number.

And fix messages on memory allocation fails - add details that it's

The bug introduced by commit 8c7396aebb
("gianfar: Merge Tx and Rx interrupt for scheduling clean up ring").

The commit merged TX and RX interrupt code into a single routine that
schedules NAPI, but no locks were introduced. This causes irq races, so
when irqs are enabled and netif_rx_schedule_prep() returns 0, nobody
disable the interrupts again. This leads to interrupt storm and finally
to the lockup.

da9dc13289 hvc_console: Do not set low_latency when using interrupts
hvc_console is setting low_latency unconditionally, but some clients are
interrupt driven and will call hvc_poll from irq context.  This will cause
tty_flip_buffer_push to be called from irq context, and it very clearly

v2.6.16-rc5 via fb5c594c2a

said set this flag to avoid a stall problem, and was merged through

Without searching for email discussions, it would appear to be an

This will avoid reoccuring spurious warnings in core kernel code that
comes when people test on their own hardware. (i.e. x86 in ~98% of the

50df48f59d IPoIB: Do not join broadcast group if interface is brought down
Because the ipoib_workqueue is not flushed when ipoib interface is
brought down, ipoib_mcast_join() may trigger a join to the broadcast
group after priv->broadcast was set to NULL (during cleanup).  This
will cause the system to be a member of the broadcast group when
interface is down.  As a side effect, this breaks the optimization of
setting the Q_key only when joining the broadcast group.

6d0be946e1 m68k: amiflop - Get rid of sleep_on calls
Apart from sleep_on() calls that could be easily converted to
wait_event() and completion calls amiflop also used a flag in ms_delay()
and ms_isr() as a custom mutex for ms_delay() without a need for
explicit unlocking.  I converted that to a standard mutex.

The replacement for the unconditional sleep_on() in fd_motor_on() is a
complete_all() together with a INIT_COMPLETION() before the mod_timer()
call.  It appears to me that fd_motor_on() might be called concurrently
and fd_select() does not guarantee mutual exclusivity in the case the
same drive gets selected again.

f1dd2b23ba rt2x00: Fix rt2500usb HW crypto: WEP 128 & AES
The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value
to indicate if the frame must be encrypted or not.

The way rt2x00_set_field32() worked it would grab the least signifcant bit
from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP
worked since they had odd-numbered values, while WEP 128 and AES were
even numbers and didn't work.

Correctly booleanize the txdecs->cipher value to allow the hardware to
encrypt the outgoing data. After this we can enable HW crypto by default again.

157ec87684 ath9k: Revert fix to TX status reporting for retries and MCS index
This patch reverts "ath9k: Fix TX status reporting for retries and MCS index"
because that change ended up breaking ath9k rate control. While the
MCS index reporting to mac80211 was indeed fixed by the patch, it did
not take into account that the ath9k rate control algorithm was
updating private tables based on this index and the index comes
through the rate control API call, i.e., based on mac80211 TX status
call. In addition, it looks like the "fix" to remove +1 from TX status
'count' field was not correct based on ieee80211_tx_status()
implementation that counts the total of count values, but starting
from -1, not 0.

The TX status reporting for frames using MCS needs to be fixed
somehow, but it does not look like there is any easy fix for the ath9k
rate control algorithm, so the best option now seems to be to revert the
change and bring it back once the rate control code is cleaned up to
handle this better.

The queue_end() macro points to 1 position after the

This fixes a segmentation fault which only occurs when
the device has enough endpoints to provide a dedicated
endpoint for all TX queues (which likely won't happen
for rt2500usb and rt73usb, but will happen for rt2800usb).

c1d34c1dad p54: crypto offload fixes
This patch fixes two small flaws:
 - restore the original TKIP IV if we altered it.
 - reserve & initialize ICV with zeros.
   This is actually only necessary for some obsolete p54usb firmwares.
   But we don't know yet, if all devices are compatible with the new revisions.

20953ad68e orinoco: take the driver lock in the rx tasklet
Fix the warning reproduced below.

We add to rx_list in interrupt context and remove elements in tasklet
context. While removing elements we need to prevent the interrupt
modifying the list.

Note that "orinoco: Process bulk of receive interrupt in a tasklet" did not
preserve locking semantics on what is now orinoco_rx.

This patch reinstates the locking semantics and ensures it covers
rx_list as well. This leads to additional cleanup required in
free_orinocodev.

CONFIG_ATH9K=y results in build issues if CONFIG_RFKILL=m since ath9k
does not depend on rfkill in kconfig (i.e., CONFIG_RFKILL is used to
select whether to enable rfkill in ath9k), but uses its functions if
rfkill is enabled. Enforce ath9k to be build as a module if
CONFIG_RFKILL=m to avoid this invalid configuration.

47fd23fe8e cxgb3: Keep LRO off if disabled when interface is down
I have a system with a Chelsio adapter (driven by cxgb3) whose ports are
part of a Linux bridge.  Recently I updated the kernel and discovered
that things stopped working because cxgb3 was doing LRO on packets that
were passed into the bridge code for forwarding.  (Incidentally, this
problem manifested itself in a strange way that made debugging a bit
interesting -- for some reason, the skb_warn_if_lro() check in bridge
didn't trigger and these LROed packets were forwarded out a forcedeth
interface, and caused the forcedeth transmit path to get stuck)

This is because cxgb3 has no way of keeping state for the LRO flag until
the interface is brought up, so if the bridging code disables LRO while
the interface is down, then cxgb3_up() will just reenable LRO, and on my
Debian system at least, the init scripts add interfaces to a bridge
before bringing the interfaces up.

Fix this by keeping track of each interface's LRO state in cxgb3 so that
when bridge disables LRO, it stays disabled in cxgb3_up() when the
interface is brought up.  I did this by changing the rx_csum_offload
flag into a pair of bit flags; the effect of this on the rx_eth() fast
path is miniscule enough that it should be fine (eg on x86, a cmpb
instruction becomes a testb instruction).
