Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking update from David S. Miller: "I think Eric Dumazet and I have dealt with all of the known routing cache removal fallout. Some other minor fixes all around. 1) Fix RCU of cached routes, particular of output routes which require liberation via call_rcu() instead of call_rcu_bh(). From Eric Dumazet. 2) Make sure we purge net device references in cached routes properly. 3) TG3 driver bug fixes from Michael Chan. 4) Fix reported 'expires' value in ipv6 routes, from Li Wei. 5) TUN driver ioctl leaks kernel bytes to userspace, from Mathias Krause." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (22 commits) ipv4: Properly purge netdev references on uncached routes. ipv4: Cache routes in nexthop exception entries. ipv4: percpu nh_rth_output cache ipv4: Restore old dst_free() behavior. bridge: make port attributes const ipv4: remove rt_cache_rebuild_count net: ipv4: fix RCU races on dst refcounts net: TCP early demux cleanup tun: Fix formatting. net/tun: fix ioctl() based info leaks tg3: Update version to 3.124 tg3: Fix race condition in tg3_get_stats64() tg3: Add New 5719 Read DMA workaround tg3: Fix Read DMA workaround for 5719 A0. tg3: Request APE_LOCK_PHY before PHY access ipv6: fix incorrect route 'expires' value passed to userspace mISDN: Bugfix only few bytes are transfered on a connection seeq: use PTR_RET at init_module of driver bnx2x: remove cast around the kmalloc in bnx2x_prev_mark_path ipv4: clean up put_child ...
