Merge tag 'net-6.1-rc3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf.

  The net-memcg fix stands out, the rest is very run-off-the-mill. Maybe
  I'm biased.

  Current release - regressions:

   - eth: fman: re-expose location of the MAC address to userspace,
     apparently some udev scripts depended on the exact value

  Current release - new code bugs:

   - bpf:
       - wait for busy refill_work when destroying bpf memory allocator
       - allow bpf_user_ringbuf_drain() callbacks to return 1
       - fix dispatcher patchable function entry to 5 bytes nop

  Previous releases - regressions:

   - net-memcg: avoid stalls when under memory pressure

   - tcp: fix indefinite deferral of RTO with SACK reneging

   - tipc: fix a null-ptr-deref in tipc_topsrv_accept

   - eth: macb: specify PHY PM management done by MAC

   - tcp: fix a signed-integer-overflow bug in tcp_add_backlog()

  Previous releases - always broken:

   - eth: amd-xgbe: SFP fixes and compatibility improvements

  Misc:

   - docs: netdev: offer performance feedback to contributors"

+My company uses peer feedback in employee performance reviews. Can I ask netdev maintainers for feedback?
+---------------------------------------------------------------------------------------------------------
+
+Yes, especially if you spend significant amount of time reviewing code
+and go out of your way to improve shared infrastructure.
+
+The feedback must be requested by you, the contributor, and will always
+be shared with you (even if you request for it to be submitted to your
+manager).
