Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) kvaser CAN driver has fixed limits of some of it's table, validate that we won't exceed those limits at probe time. Fix from Olivier Sobrie. 2) Fix rtl8192ce disabling interrupts for too long, from Olivier Langlois. 3) Fix botched shift in ath5k driver, from Dan Carpenter. 4) Fix corruption of deferred packets in TIPC, from Erik Hugne. 5) Fix newlink error path in macvlan driver, from Cong Wang. 6) Fix netpoll deadlock in bonding, from Ding Tianhong. 7) Handle GSO packets properly in forwarding path when fragmentation is necessary on egress, from Florian Westphal. 8) Fix axienet build errors, from Michal Simek. 9) Fix refcounting of ubufs on tx in vhost net driver, from Michael S Tsirkin. 10) Carrier status isn't set properly in hyperv driver, from Haiyang Zhang. 11) Missing pci_disable_device() in tulip_remove_one), from Ingo Molnar. 12) AF_PACKET qdisc bypass mode doesn't adhere to driver provided TX queue selection method. Add a fallback method mechanism to fix this bug, from Daniel Borkmann. 13) Fix regression in link local route handling on GRE tunnels, from Nicolas Dichtel. 14) Bonding can assign dup aggregator IDs in some sequences of configuration, fix by making the allocation counter per-bond instead of global. From Jiri Bohac. 15) sctp_connectx() needs compat translations, from Daniel Borkmann. 16) Fix of_mdio PHY interrupt parsing, from Ben Dooks * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (62 commits) MAINTAINERS: add entry for the PHY library of_mdio: fix phy interrupt passing net: ethernet: update dependency and help text of mvneta NET: fec: only enable napi if we are successful af_packet: remove a stray tab in packet_set_ring() net: sctp: fix sctp_connectx abi for ia32 emulation/compat mode ipv4: fix counter in_slow_tot irtty-sir.c: Do not set_termios() on irtty_close() bonding: 802.3ad: make aggregator_identifier bond-private usbnet: remove generic hard_header_len check gre: add link local route when local addr is any batman-adv: fix potential kernel paging error for unicast transmissions batman-adv: avoid double free when orig_node initialization fails batman-adv: free skb on TVLV parsing success batman-adv: fix TT CRC computation by ensuring byte order batman-adv: fix potential orig_node reference leak batman-adv: avoid potential race condition when adding a new neighbour batman-adv: properly check pskb_may_pull return value batman-adv: release vlan object after checking the CRC batman-adv: fix TT-TVLV parsing on OGM reception ...
