Merge tag 'net-5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf, mac80211.

  Current release - regressions:

   - devlink: don't throw an error if flash notification sent before
     devlink visible

   - page_pool: Revert "page_pool: disable dma mapping support...",
     turns out there are active arches who need it

  Current release - new code bugs:

   - amt: cancel delayed_work synchronously in amt_fini()

  Previous releases - regressions:

   - xsk: fix crash on double free in buffer pool

   - bpf: fix inner map state pruning regression causing program
     rejections

   - mac80211: drop check for DONT_REORDER in __ieee80211_select_queue,
     preventing mis-selecting the best effort queue

   - mac80211: do not access the IV when it was stripped

   - mac80211: fix radiotap header generation, off-by-one

   - nl80211: fix getting radio statistics in survey dump

   - e100: fix device suspend/resume

  Previous releases - always broken:

   - tcp: fix uninitialized access in skb frags array for Rx 0cp

   - bpf: fix toctou on read-only map's constant scalar tracking

   - bpf: forbid bpf_ktime_get_coarse_ns and bpf_timer_* in tracing
     progs

   - tipc: only accept encrypted MSG_CRYPTO msgs

   - smc: transfer remaining wait queue entries during fallback, fix
     missing wake ups

   - udp: validate checksum in udp_read_sock() (when sockmap is used)

   - sched: act_mirred: drop dst for the direction from egress to
     ingress

   - virtio_net_hdr_to_skb: count transport header in UFO, prevent
     allowing bad skbs into the stack

   - nfc: reorder the logic in nfc_{un,}register_device, fix unregister

   - ipsec: check return value of ipv6_skip_exthdr

   - usb: r8152: add MAC passthrough support for more Lenovo Docks"
