Networking fixes for 5.19-rc1, including fixes from bpf, and netfilter.

Browse Source 
Current release - new code bugs:
 
  - af_packet: make sure to pull the MAC header, avoid skb panic in GSO
 
  - ptp_clockmatrix: fix inverted logic in is_single_shot()
 
  - netfilter: flowtable: fix missing FLOWI_FLAG_ANYSRC flag
 
  - dt-bindings: net: adin: fix adi,phy-output-clock description syntax
 
  - wifi: iwlwifi: pcie: rename CAUSE macro, avoid MIPS build warning
 
 Previous releases - regressions:
 
  - Revert "net: af_key: add check for pfkey_broadcast in function
    pfkey_process"
 
  - tcp: fix tcp_mtup_probe_success vs wrong snd_cwnd
 
  - nf_tables: disallow non-stateful expression in sets earlier
 
  - nft_limit: clone packet limits' cost value
 
  - nf_tables: double hook unregistration in netns path
 
  - ping6: fix ping -6 with interface name
 
 Previous releases - always broken:
 
  - sched: fix memory barriers to prevent skbs from getting stuck
    in lockless qdiscs
 
  - neigh: set lower cap for neigh_managed_work rearming, avoid
    constantly scheduling the probe work
 
  - bpf: fix probe read error on big endian in ___bpf_prog_run()
 
  - amt: memory leak and error handling fixes
 
 Misc:
 
  - ipv6: expand & rename accept_unsolicited_na to accept_untracked_na

By default this is turned off.
accept_unsolicited_na - BOOLEAN
Add a new neighbour cache entry in STALE state for routers on receiving an
unsolicited neighbour advertisement with target link-layer address option
specified. This is as per router-side behavior documented in RFC9131.
This has lower precedence than drop_unsolicited_na.
accept_untracked_na - BOOLEAN
Add a new neighbour cache entry in STALE state for routers on receiving a
neighbour advertisement (either solicited or unsolicited) with target
link-layer address option specified if no neighbour entry is already
present for the advertised IPv6 address. Without this knob, NAs received
for untracked addresses (absent in neighbour cache) are silently ignored.
