Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6
* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: (30 commits) [IPSEC] IPV6: Fix to add tunnel mode SA correctly. [NET]: Cut off the queue_mapping field from sk_buff [NET]: Hide the queue_mapping field inside netif_subqueue_stopped [NET]: Make and use skb_get_queue_mapping [NET]: Use the skb_set_queue_mapping where appropriate [INET]: Use MODULE_ALIAS_NET_PF_PROTO_TYPE where possible. [INET]: Let inet_diag and friends autoload [NIU]: Cleanup PAGE_SIZE checks a bit [NET]: Fix SKB_WITH_OVERHEAD calculation [ATM]: Fix clip module reload crash. [TG3]: Update version to 3.85 [TG3]: PCI command adjustment [TG3]: Add management FW version to ethtool report [TG3]: Add 5723 support [Bluetooth] Convert RFCOMM to use kthread API [Bluetooth] Add constant for Bluetooth socket options level [Bluetooth] Add support for handling simple eSCO links [Bluetooth] Add address and channel attribute to RFCOMM TTY device [Bluetooth] Fix wrong argument in debug code of HIDP [Bluetooth] Add generic driver for Bluetooth USB devices ...
