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.
