Merge tag 'net-7.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Looks like our attempt to keep the PRs smaller have only prevented
  this one from getting even bigger. In the last 9 days there were
  405 postings explicitly tagged with [PATCH net], vs 687 with [PATCH
  net-next]. 37% of posted patches being fixes is pretty crazy, and
  that's likely undercounting because LLM "researchers" more often post
  fixes without knowing to tag the patches for specific trees. I don't
  have historic data.

  In any case, we keep adjusting the criteria. The next PR will be
  smaller.

  Current release - regressions:

   - net: defer netdev KOBJ_ADD uevent until the device is published,
     previously rtnl_lock would serialize the accesses vs publishing

   - net: explicitly cancel work to avoid races with ref tracker exit

   - qrtr: ns: raise lookup limit to 128

   - eth: hns3: fix speed configuration residue after driver reload

  Previous releases - regressions:

   - tcp: do not change rcv_ssthresh in tcp_measure_rcv_mss(), regressed
     flows with MSS and scaling_ratio variability

   - Revert "net: thunderbolt: Enable end-to-end flow control also in
     transmit", broke some platforms (no packets coming thru)

   - eth: stmmac: resume PHY before hardware setup when opening the
     interface

  Previous releases - always broken:

   - another pile of fixes for less common protocols (SCTP, TLS, SMC
     etc.)

   - close a couple of AF_PACKET bugs and ways it can build skbs
     problematic for the rest of the stack

   - bridge: mrp: fix uninitialised bytes on the wire

   - net: devmem: prevent net-iov / page mixing, avoid crashes

   - eth: atlantic: free RX pages of consumed but not refilled buffers"
