Pull networking fixes from Jakub Kicinski: "Including fixes from bpf and netfilter. 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" * tag 'net-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (80 commits) net/af_packet: make sure to pull mac header net: add debug info to __skb_pull() net: CONFIG_DEBUG_NET depends on CONFIG_NET stmmac: intel: Add RPL-P PCI ID net: stmmac: use dev_err_probe() for reporting mdio bus registration failure tipc: check attribute length for bearer name ice: fix access-beyond-end in the switch code nfp: remove padding in nfp_nfdk_tx_desc ax25: Fix ax25 session cleanup problems net: usb: qmi_wwan: Add support for Cinterion MV31 with new baseline sfc/siena: fix wrong tx channel offset with efx_separate_tx_channels sfc/siena: fix considering that all channels have TX queues socket: Don't use u8 type in uapi socket.h net/sched: act_api: fix error code in tcf_ct_flow_table_fill_tuple_ipv6() net: ping6: Fix ping -6 with interface name macsec: fix UAF bug for real_dev octeontx2-af: fix error code in is_valid_offset() wifi: mac80211: fix use-after-free in chanctx code bonding: guard ns_targets by CONFIG_IPV6 tcp: tcp_rtx_synack() can be called from process context ...
