This patch provides a sysfs interface to change some properties of the
ibmveth buffer pools (size of the buffers, number of buffers per pool,
and whether a pool is active). Ethernet drivers use ethtool to provide
this type of functionality. However, the buffers in the ibmveth driver
can have an arbitrary size (not only regular, mini, and jumbo which are
the only sizes that ethtool can change), and also ibmveth can have an
arbitrary number of buffer pools
Under heavy load we have seen dropped packets which obviously kills TCP
performance. We have created several fixes that mitigate this issue,
but we definitely need a way of changing the number of buffers for an
adapter dynamically. Also, changing the size of the buffers allows
users to change the MTU to something big (bigger than a jumbo frame)
greatly improving performance on partition to partition transfers.
The patch creates directories pool1...pool4 in the device directory in
sysfs, each with files: num, size, and active (which default to the
values in the mainline version).
Comments and suggestions are welcome...

If both ports are receiving on the SysKonnect dual port cards,
then it appears the bus interface unit can give an interrupt status
for frame before DMA has completed. This leads to bogus frames
and general confusion. This is why receive checksumming is also
messed up on dual port cards.
A workaround for the out of order receive problem is to eliminating
split transactions on PCI-X.
This version is based of the current linux-2.6.git including earlier

When both ports are receiving simultaneously, the receive logic gets confused
and may pass up a packet before it is full. This causes hangs, and IP will see
lots of garbage packets. There is even the potential for data corruption if
a later arriving packet DMA's into freed memory.
It looks like a hardware bug because status arrives for a packet but no
data is there. Until this bug is worked out, block the user from bringing
up both ports at once.

661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds
an entry to mii_chip_info for the transceiver.
The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.
Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits. There were fifth second pauses in refresh of large xterms,
and it made Netrek suck. I can provide further test data.
Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.
I wasn't able to identify the actual transceiver, so the description
field is a guess.
This patch is similar to Artur Skawina's patch:

I'm not sure, but I wonder if it means the default behaviour should be

Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.
Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded. On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding. This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.
Now zero-padding is repeated in the local aligned buffer if one is used.
Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used. This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary. There is no change to the flow of control and the changes are
only to the Rhine I code path.
The patch has run on an in-service Rhine-I host without incident. Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host. I see no unusual stats reported by ifconfig, and no unusual
log messages.

With this patch, a new promiscuous mode is enabled. If the module is loaded
with the rtap_iface=1 module parameter, two interfaces will be created
(instead of just one).
The second interface is prefixed 'rtap' and provides received 802.11 frames
on the current channel to user space in a radiotap header format.
Example usage:
% modprobe ipw2200 rtap_iface=1
% iwconfig eth1 essid MyNetwork
% dhcpcd eth1
% tcpdump -i rtap0
If you do not specify 'rtap_iface=1' then the rtap interface will
not be created and you will need to turn it on via:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
You can filter out what type of information is passed to user space via
the rtap_filter sysfs entry. Currently you can tell the driver to
transmit just the headers (which will provide the RADIOTAP and IEEE
802.11 header but not the payload), to filter based on frame control
type (Management, Control, or Data), and whether to report transmitted
frames, received frames, or both.
The transmit frame reporting is based on a patch by Stefan Rompf.
Filters can be get and set via a sysfs interface. For example, set the
filter to only send headers (0x7), don't report Tx'd frames (0x10), and
don't report data frames (0x100):
% echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter
All your packets are belong to us:
