Pull more networking updates from David Miller: "Ok, everything from here on out will be bug fixes." 1) One final sync of wireless and bluetooth stuff from John Linville. These changes have all been in his tree for more than a week, and therefore have had the necessary -next exposure. John was just away on a trip and didn't have a change to send the pull request until a day or two ago. 2) Put back some defines in user exposed header file areas that were removed during the tokenring purge. From Stephen Hemminger and Paul Gortmaker. 3) A bug fix for UDP hash table allocation got lost in the pile due to one of those "you got it.. no I've got it.." situations. :-) From Tim Bird. 4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll try to coalesce overlapping frags and crash. Fix from Eric Dumazet. 5) RCU routing table lookups can race with free_fib_info(), causing crashes when we deref the device pointers in the route. Fix by releasing the net device in the RCU callback. From Yanmin Zhang. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (293 commits) tcp: take care of overlaps in tcp_try_coalesce() ipv4: fix the rcu race between free_fib_info and ip_route_output_slow mm: add a low limit to alloc_large_system_hash ipx: restore token ring define to include/linux/ipx.h if: restore token ring ARP type to header xen: do not disable netfront in dom0 phy/micrel: Fix ID of KSZ9021 mISDN: Add X-Tensions USB ISDN TA XC-525 gianfar:don't add FCB length to hard_header_len Bluetooth: Report proper error number in disconnection Bluetooth: Create flags for bt_sk() Bluetooth: report the right security level in getsockopt Bluetooth: Lock the L2CAP channel when sending Bluetooth: Restore locking semantics when looking up L2CAP channels Bluetooth: Fix a redundant and problematic incoming MTU check Bluetooth: Add support for Foxconn/Hon Hai AR5BBU22 0489:E03C Bluetooth: Fix EIR data generation for mgmt_device_found Bluetooth: Fix Inquiry with RSSI event mask Bluetooth: improve readability of l2cap_seq_list code Bluetooth: Fix skb length calculation ...
