[PATCH 9/9] s390: qeth driver fixes [6/6]
From: Frank Pavlic <fpavlic@de.ibm.com>
- Hipersockets has no IPV6 support, thus prevent issueing
SETRTG_IPV6 control commands on Hipersockets devices.
- fixed error handling in qeth_sysfs_(un)register

[PATCH 7/9] s390: qeth driver fixes [4/6]
From: Frank Pavlic <fpavlic@de.ibm.com>
- fix kernel crash due to race,
set card->state to SOFTSETUP after
card and card->dev are initialized properly.
- remove CONFIG_QETH_PERF_STATS, use sysfs attribute instead,
as we want to have the ability to turn on/off the
statistics at runtime.

[PATCH 6/9] s390: qeth driver fixes [3/6]
From: Frank Pavlic <fpavlic@de.ibm.com>
fixed kernel panic caused by qeth driver:
Using a bonding device qeth driver will realloc
headroom for every skb coming from the bond device.
Once this happens qeth frees the original skb and
set the skb pointer to the new realloced skb.
Under heavy transmit workload (e.g.UDP streams) through bond
network device the qdio output queue might get full.
In this case we return with EBUSY from qeth_send_packet.
Returning to qeth_hard_start_xmit routine
the skb address on the stack still points to the old address,
which has been freed before.
Returning from qeth_hard_start_xmit with EBUSY results in
requeuing the skb. In this case it corrupts the qdisc queue
and results in kernel panic.

Hi Jeff,
this is a RESEND of the nine s390 network driver patches.
I finally found that my kmail corrupted almost every patch
I sent the last time. Please apply these 9 patches and forget

If there is a problem in the connection, the SCSI mid-layer will
eventually call srp_reset_host(), which will call srp_reconnect(), so
we do not need to schedule a call to srp_reconnect_work() from
srp_completion().
Removing this prevents srp_reset_host() from failing if a reconnect
scheduled from srp_completion() is already in progress, which in turn
was causing crashes as both SCSI midlayer and srp_reconnect() were
cancelling commands.

Implement NAPI changes to pcnet32 driver. Compile default is off.
Listed as experimental.
Len and Don both worked on a NAPI implementation and have both tested
these changes.
An e1000 blasting short packets to the pcnet32 will lockup Don's system
until the receive storm stops. Without NAPI Len's system watchdog would
expire causing the system to reboot. With NAPI the system will stay
operational.
Tested ia32 and ppc64. Tested '970A, '971, '972, '973, '975, '976, and
'978.
The Kconfig changes came from Len. Don is to blame for all the others.
