Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: (109 commits) [ETHTOOL]: Fix UFO typo [SCTP]: Fix persistent slowdown in sctp when a gap ack consumes rx buffer. [SCTP]: Send only 1 window update SACK per message. [SCTP]: Don't do CRC32C checksum over loopback. [SCTP] Reset rtt_in_progress for the chunk when processing its sack. [SCTP]: Reject sctp packets with broadcast addresses. [SCTP]: Limit association max_retrans setting in setsockopt. [PFKEYV2]: Fix inconsistent typing in struct sadb_x_kmprivate. [IPV6]: Sum real space for RTAs. [IRDA]: Use put_unaligned() in irlmp_do_discovery(). [BRIDGE]: Add support for NETIF_F_HW_CSUM devices [NET]: Add NETIF_F_GEN_CSUM and NETIF_F_ALL_CSUM [TG3]: Convert to non-LLTX [TG3]: Remove unnecessary tx_lock [TCP]: Add tcp_slow_start_after_idle sysctl. [BNX2]: Update version and reldate [BNX2]: Use CPU native page size [BNX2]: Use compressed firmware [BNX2]: Add firmware decompression [BNX2]: Allow WoL settings on new 5708 chips ... Manual fixup for conflict in drivers/net/tulip/winbond-840.c
