* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (21 commits) [PKT_SCHED]: vlan tag match [NET]: Add if_addrlabel.h to sanitized headers. [NET] rtnetlink.c: remove no longer used functions [ICMP]: Restore pskb_pull calls in receive function [INET]: Fix accidentally broken inet(6)_hash_connect's port offset calculations. [NET]: Remove further references to net-modules.txt bluetooth rfcomm tty: destroy before tty_close() bluetooth: blacklist another Broadcom BCM2035 device drivers/bluetooth/btsdio.c: fix double-free drivers/bluetooth/bpa10x.c: fix memleak bluetooth: uninlining bluetooth: hidp_process_hid_control remove unnecessary parameter dealing tun: impossible to deassert IFF_ONE_QUEUE or IFF_NO_PI hamradio: fix dmascc section mismatch [SCTP]: Fix kernel panic while received AUTH chunk with BAD shared key identifier [SCTP]: Fix kernel panic while received AUTH chunk while enabled auth [IPV4]: Formatting fix for /proc/net/fib_trie. [IPV6]: Fix sysctl compilation error. [NET_SCHED]: Add #ifdef CONFIG_NET_EMATCH in net/sched/cls_flow.c (latest git broken build) [IPV4]: Fix compile error building without CONFIG_FS_PROC ...
