Revision da241efcd9c3da2af6ba20055c7e158ec725005c authored by Linus Torvalds on 03 April 2013, 01:58:01 UTC, committed by Linus Torvalds on 03 April 2013, 01:58:01 UTC
Pull networking fixes from David Miller: 1) Fix VSOCK layer handling of context ID changes, from Reilly Grant. 2) Now that we have a synchronize_net() in netdev_rx_handler_unregister(), we can't let any call sites hold locks. Unfortunately bonding does, so we have to drop the rwlock there a little bit earlier, fix from Veaceslav Falico. 3) MAC address setting loop exits one iteration too early in mlx4 driver, from Yan Burman. 4) Restore ipv6 routes properly upon ifdown/ifup of loopback, from Balakumaran Kannan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: Handle changes to the VMCI context ID. net IPv6 : Fix broken IPv6 routing table after loopback down-up cbq: incorrect processing of high limits net/mlx4_en: Fix setting initial MAC address bonding: get netdev_rx_handler_unregister out of locks
