Subject: [git patches] net driver updates
Please pull from 'upstream-davem' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-davem
to receive the following updates:
Auke Kok (2):
e1000e: fix debugging printout code
e1000e: Fix ethtool register test code
Frank Blaschka (1):
qeth: EDDP does not work on large MTUs
Klaus D. Wacker (2):
qeth: HiperSockets layer-3 interface drop non IPv4 or non IPv6 packets
lcs: Channel errors drive lcs_recovery which leads to kernel panic.
Ursula Braun (2):
qeth: avoid duplicate deletion of multicast addresses
qeth: discard inbound packets with unknown header id
