Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking updates from David Miller: 1) ax88796 does 64-bit divides which causes link errors on ARM, fix from Arnd Bergmann. 2) Once an improper offload setting is detected on an SKB we don't rate limit the log message so we can very easily live lock. From Ben Greear. 3) Openvswitch cannot report vport configuration changes reliably because it didn't preallocate the netlink notification message before changing state. From Jesse Gross. 4) The effective UID/GID SCM credentials fix, from Linus. 5) When a user explicitly asks for wireless authentication, cfg80211 isn't told about the AP detachment leaving inconsistent state. Fix from Johannes Berg. 6) Fix self-MAC checks in batman-adv on multi-mesh nodes, from Antonio Quartulli. 7) Revert build_skb() change sin IGB driver, can result in memory corruption. From Alexander Duyck. 8) Fix setting VLANs on virtual functions in IXGBE, from Greg Rose. 9) Fix TSO races in qlcnic driver, from Sritej Velaga. 10) In bnx2x the kernel driver and UNDI firmware can try to program the chip at the same time, resulting in corruption. Add proper synchronization. From Dmitry Kravkov. 11) Fix corruption of status block in firmware ram in bxn2x, from Ariel Elior. 12) Fix load balancing hash regression of bonding driver in forwarding configurations, from Eric Dumazet. 13) Fix TS ECR regression in TCP by calling tcp_replace_ts_recent() in all the right spots, from Eric Dumazet. 14) Fix several bonding bugs having to do with address manintainence, including not removing address when configuration operations encounter errors, missed locking on the address lists, missing refcounting on VLAN objects, etc. All from Nikolay Aleksandrov. 15) Add workarounds for firmware bugs in LTE qmi_wwan devices, wherein the devices fail to add a proper ethernet header while on LTE networks but otherwise properly do so on 2G and 3G ones. From Bjørn Mork. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (38 commits) net: fix incorrect credentials passing net: rate-limit warn-bad-offload splats. net: ax88796: avoid 64 bit arithmetic qlge: Update version to 1.00.00.32. qlge: Fix ethtool autoneg advertising. qlge: Fix receive path to drop error frames net: qmi_wwan: prevent duplicate mac address on link (firmware bug workaround) net: qmi_wwan: fixup destination address (firmware bug workaround) net: qmi_wwan: fixup missing ethernet header (firmware bug workaround) bonding: in bond_mc_swap() bond's mc addr list is walked without lock bonding: disable netpoll on enslave failure bonding: primary_slave & curr_active_slave are not cleaned on enslave failure bonding: vlans don't get deleted on enslave failure bonding: mc addresses don't get deleted on enslave failure pkt_sched: fix error return code in fw_change_attrs() irda: small read past the end of array in debug code tcp: call tcp_replace_ts_recent() from tcp_ack() netfilter: xt_rpfilter: skip locally generated broadcast/multicast, too netfilter: ipset: bitmap:ip,mac: fix listing with timeout bonding: fix l23 and l34 load balancing in forwarding path ...
