Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from David Miller: 1) Unbalanced locking in mwifiex_process_country_ie, from Brian Norris. 2) Fix thermal zone registration in iwlwifi, from Andrei Otcheretianski. 3) Fix double free_irq in sgi ioc3 eth, from Thomas Bogendoerfer. 4) Use after free in mptcp, from Florian Westphal. 5) Use after free in wireguard's root_remove_peer_lists, from Eric Dumazet. 6) Properly access packets heads in bonding alb code, from Eric Dumazet. 7) Fix data race in skb_queue_len(), from Qian Cai. 8) Fix regression in r8169 on some chips, from Heiner Kallweit. 9) Fix XDP program ref counting in hv_netvsc, from Haiyang Zhang. 10) Certain kinds of set link netlink operations can cause a NULL deref in the ipv6 addrconf code. Fix from Eric Dumazet. 11) Don't cancel uninitialized work queue in drop monitor, from Ido Schimmel. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (84 commits) net: thunderx: use proper interface type for RGMII mt76: mt7615: fix max_nss in mt7615_eeprom_parse_hw_cap bpf: Improve bucket_log calculation logic selftests/bpf: Test freeing sockmap/sockhash with a socket in it bpf, sockhash: Synchronize_rcu before free'ing map bpf, sockmap: Don't sleep while holding RCU lock on tear-down bpftool: Don't crash on missing xlated program instructions bpf, sockmap: Check update requirements after locking drop_monitor: Do not cancel uninitialized work item mlxsw: spectrum_dpipe: Add missing error path mlxsw: core: Add validation of hardware device types for MGPIR register mlxsw: spectrum_router: Clear offload indication from IPv6 nexthops on abort selftests: mlxsw: Add test cases for local table route replacement mlxsw: spectrum_router: Prevent incorrect replacement of local table routes net: dsa: microchip: enable module autoprobe ipv6/addrconf: fix potential NULL deref in inet6_set_link_af() dpaa_eth: support all modes with rate adapting PHYs net: stmmac: update pci platform data to use phy_interface net: stmmac: xgmac: fix missing IFF_MULTICAST checki in dwxgmac2_set_filter net: stmmac: fix missing IFF_MULTICAST check in dwmac4_set_filter ...
