Pull networking fixes from Jakub Kicinski:
 "Networking fixes, including fixes from can and bpf.

  Closing three hw-dependent regressions. Any fixes of note are in the
  'old code' category. Nothing blocking release from our perspective.

  Current release - regressions:

   - stmmac: revert "stmmac: align RX buffers"

   - usb: asix: ax88772: move embedded PHY detection as early as
     possible

   - usb: asix: do not call phy_disconnect() for ax88178

   - Revert "net: really fix the build...", from Kalle to fix QCA6390

  Current release - new code bugs:

   - phy: mediatek: add the missing suspend/resume callbacks

  Previous releases - regressions:

   - qrtr: fix another OOB Read in qrtr_endpoint_post

   - stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings

  Previous releases - always broken:

   - inet: use siphash in exception handling

   - ip_gre: add validation for csum_start

   - bpf: fix ringbuf helper function compatibility

   - rtnetlink: return correct error on changing device netns

   - e1000e: do not try to recover the NVM checksum on Tiger Lake"
