Pull networking fixes from Jakub Kicinski: - fix failure to add bond interfaces to a bridge, the offload-handling code was too defensive there and recent refactoring unearthed that. Users complained (Ido) - fix unnecessarily reflecting ECN bits within TOS values / QoS marking in TCP ACK and reset packets (Wei) - fix a deadlock with bpf iterator. Hopefully we're in the clear on this front now... (Yonghong) - BPF fix for clobbering r2 in bpf_gen_ld_abs (Daniel) - fix AQL on mt76 devices with FW rate control and add a couple of AQL issues in mac80211 code (Felix) - fix authentication issue with mwifiex (Maximilian) - WiFi connectivity fix: revert IGTK support in ti/wlcore (Mauro) - fix exception handling for multipath routes via same device (David Ahern) - revert back to a BH spin lock flavor for nsid_lock: there are paths which do require the BH context protection (Taehee) - fix interrupt / queue / NAPI handling in the lantiq driver (Hauke) - fix ife module load deadlock (Cong) - make an adjustment to netlink reply message type for code added in this release (the sole change touching uAPI here) (Michal) - a number of fixes for small NXP and Microchip switches (Vladimir) [ Pull request acked by David: "you can expect more of this in the future as I try to delegate more things to Jakub" ] * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (167 commits) net: mscc: ocelot: fix some key offsets for IP4_TCP_UDP VCAP IS2 entries net: dsa: seville: fix some key offsets for IP4_TCP_UDP VCAP IS2 entries net: dsa: felix: fix some key offsets for IP4_TCP_UDP VCAP IS2 entries inet_diag: validate INET_DIAG_REQ_PROTOCOL attribute net: bridge: br_vlan_get_pvid_rcu() should dereference the VLAN group under RCU net: Update MAINTAINERS for MediaTek switch driver net/mlx5e: mlx5e_fec_in_caps() returns a boolean net/mlx5e: kTLS, Avoid kzalloc(GFP_KERNEL) under spinlock net/mlx5e: kTLS, Fix leak on resync error flow net/mlx5e: kTLS, Add missing dma_unmap in RX resync net/mlx5e: kTLS, Fix napi sync and possible use-after-free net/mlx5e: TLS, Do not expose FPGA TLS counter if not supported net/mlx5e: Fix using wrong stats_grps in mlx5e_update_ndo_stats() net/mlx5e: Fix multicast counter not up-to-date in "ip -s" net/mlx5e: Fix endianness when calculating pedit mask first bit net/mlx5e: Enable adding peer miss rules only if merged eswitch is supported net/mlx5e: CT: Fix freeing ct_label mapping net/mlx5e: Fix memory leak of tunnel info when rule under multipath not ready net/mlx5e: Use synchronize_rcu to sync with NAPI net/mlx5e: Use RCU to protect rq->xdp_prog ...
