Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from David Miller: 1) Fix RCU warnings in ipv6 multicast router code, from Madhuparna Bhowmik. 2) Nexthop attributes aren't being checked properly because of mis-initialized iterator, from David Ahern. 3) Revert iop_idents_reserve() change as it caused performance regressions and was just working around what is really a UBSAN bug in the compiler. From Yuqi Jin. 4) Read MAC address properly from ROM in bmac driver (double iteration proceeds past end of address array), from Jeremy Kerr. 5) Add Microsoft Surface device IDs to r8152, from Marc Payne. 6) Prevent reference to freed SKB in __netif_receive_skb_core(), from Boris Sukholitko. 7) Fix ACK discard behavior in rxrpc, from David Howells. 8) Preserve flow hash across packet scrubbing in wireguard, from Jason A. Donenfeld. 9) Cap option length properly for SO_BINDTODEVICE in AX25, from Eric Dumazet. 10) Fix encryption error checking in kTLS code, from Vadim Fedorenko. 11) Missing BPF prog ref release in flow dissector, from Jakub Sitnicki. 12) dst_cache must be used with BH disabled in tipc, from Eric Dumazet. 13) Fix use after free in mlxsw driver, from Jiri Pirko. 14) Order kTLS key destruction properly in mlx5 driver, from Tariq Toukan. 15) Check devm_platform_ioremap_resource() return value properly in several drivers, from Tiezhu Yang. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (71 commits) net: smsc911x: Fix runtime PM imbalance on error net/mlx4_core: fix a memory leak bug. net: ethernet: ti: cpsw: fix ASSERT_RTNL() warning during suspend net: phy: mscc: fix initialization of the MACsec protocol mode net: stmmac: don't attach interface until resume finishes net: Fix return value about devm_platform_ioremap_resource() net/mlx5: Fix error flow in case of function_setup failure net/mlx5e: CT: Correctly get flow rule net/mlx5e: Update netdev txq on completions during closure net/mlx5: Annotate mutex destroy for root ns net/mlx5: Don't maintain a case of del_sw_func being null net/mlx5: Fix cleaning unmanaged flow tables net/mlx5: Fix memory leak in mlx5_events_init net/mlx5e: Fix inner tirs handling net/mlx5e: kTLS, Destroy key object after destroying the TIS net/mlx5e: Fix allowed tc redirect merged eswitch offload cases net/mlx5: Avoid processing commands before cmdif is ready net/mlx5: Fix a race when moving command interface to events mode net/mlx5: Add command entry handling completion rxrpc: Fix a memory leak in rxkad_verify_response() ...
