Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix OOPS during nf_tables rule dump, from Florian Westphal. 2) Use after free in ip_vs_in, from Yue Haibing. 3) Fix various kTLS bugs (NULL deref during device removal resync, netdev notification ignoring, etc.) From Jakub Kicinski. 4) Fix ipv6 redirects with VRF, from David Ahern. 5) Memory leak fix in igmpv3_del_delrec(), from Eric Dumazet. 6) Missing memory allocation failure check in ip6_ra_control(), from Gen Zhang. And likewise fix ip_ra_control(). 7) TX clean budget logic error in aquantia, from Igor Russkikh. 8) SKB leak in llc_build_and_send_ui_pkt(), from Eric Dumazet. 9) Double frees in mlx5, from Parav Pandit. 10) Fix lost MAC address in r8169 during PCI D3, from Heiner Kallweit. 11) Fix botched register access in mvpp2, from Antoine Tenart. 12) Use after free in napi_gro_frags(), from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (89 commits) net: correct zerocopy refcnt with udp MSG_MORE ethtool: Check for vlan etype or vlan tci when parsing flow_rule net: don't clear sock->sk early to avoid trouble in strparser net-gro: fix use-after-free read in napi_gro_frags() net: dsa: tag_8021q: Create a stable binary format net: dsa: tag_8021q: Change order of rx_vid setup net: mvpp2: fix bad MVPP2_TXQ_SCHED_TOKEN_CNTR_REG queue value ipv4: tcp_input: fix stack out of bounds when parsing TCP options. mlxsw: spectrum: Prevent force of 56G mlxsw: spectrum_acl: Avoid warning after identical rules insertion net: dsa: mv88e6xxx: fix handling of upper half of STATS_TYPE_PORT r8169: fix MAC address being lost in PCI D3 net: core: support XDP generic on stacked devices. netvsc: unshare skb in VF rx handler udp: Avoid post-GRO UDP checksum recalculation net: phy: dp83867: Set up RGMII TX delay net: phy: dp83867: do not call config_init twice net: phy: dp83867: increase SGMII autoneg timer duration net: phy: dp83867: fix speed 10 in sgmii mode net: phy: marvell10g: report if the PHY fails to boot firmware ...
