Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (60 commits) [NIU]: Bump driver version and release date. [NIU]: Fix BMAC alternate MAC address indexing. net: fix kernel-doc warnings in header files [IPV6]: Use BUG_ON instead of if + BUG in fib6_del_route. [IPV6]: dst_entry leak in ip4ip6_err. (resend) bluetooth: do not move child device other than rfcomm bluetooth: put hci dev after del conn [NET]: Elminate spurious print_mac() calls. [BLUETOOTH] hci_sysfs.c: Kill build warning. [NET]: Remove MAC_FMT net/8021q/vlan_dev.c: Use print_mac. [XFRM]: Fix ordering issue in xfrm_dst_hash_transfer(). [BLUETOOTH] net/bluetooth/hci_core.c: Use time_* macros [IPV6]: Fix hardcoded removing of old module code [NETLABEL]: Move some initialization code into __init section. [NETLABEL]: Shrink the genl-ops registration code. [AX25] ax25_out: check skb for NULL in ax25_kick() [TCP]: Fix tcp_v4_send_synack() comment [IPV4]: fix alignment of IP-Config output Documentation: fix tcp.txt ...
