Merge tag 'net-6.6-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from WiFi and netfilter.
Most regressions addressed here come from quite old versions, with the
exceptions of the iavf one and the WiFi fixes. No known outstanding
reports or investigation.
Fixes to fixes:
- eth: iavf: in iavf_down, disable queues when removing the driver
Previous releases - regressions:
- sched: act_ct: additional checks for outdated flows
- tcp: do not leave an empty skb in write queue
- tcp: fix wrong RTO timeout when received SACK reneging
- wifi: cfg80211: pass correct pointer to rdev_inform_bss()
- eth: i40e: sync next_to_clean and next_to_process for programming
status desc
- eth: iavf: initialize waitqueues before starting watchdog_task
Previous releases - always broken:
- eth: r8169: fix data-races
- eth: igb: fix potential memory leak in igb_add_ethtool_nfc_entry
- eth: r8152: avoid writing garbage to the adapter's registers
- eth: gtp: fix fragmentation needed check with gso"
