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" ]
