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: (22 commits) [IPCONFIG]: The kernel gets no IP from some DHCP servers b43legacy: Fix module init message rndis_wlan: fix broken data copy libertas: compare the current command with response libertas: fix sanity check on sequence number in command response p54: fix eeprom parser length sanity checks p54: fix EEPROM structure endianness ssb: Add pcibios_enable_device() return value check rc80211-pid: fix rate adjustment [ESP]: Add select on AUTHENC [TCP]: Improve ipv4 established hash function. [NETPOLL]: Revert two bogus cleanups that broke netconsole. [PPPOL2TP]: Add missing sock_put() in pppol2tp_tunnel_closeall() Subject: [PPPOL2TP] add missing sock_put() in pppol2tp_recv_dequeue() [BLUETOOTH]: l2cap info_timer delete fix in hci_conn_del [NET]: Fix race in generic address resolution. iucv: fix build error on !SMP [TCP]: Must count fack_count also when skipping [TUN]: Fix RTNL-locking in tun/tap driver [SCTP]: Use proc_create to setup de->proc_fops. ...
