Pull networking fixes from David Miller:
 "Several bug fixes, many are quick merge-window regression cures:

   - When NLM_F_EXCL is not set, allow same fib rule insertion. From
     Hangbin Liu.

   - Several cures in sja1105 DSA driver (while loop exit condition fix,
     return of negative u8, etc.) from Vladimir Oltean.

   - Handle tx/rx delays in realtek PHY driver properly, from Serge
     Semin.

   - Double free in cls_matchall, from Pieter Jansen van Vuuren.

   - Disable SIOCSHWTSTAMP in macvlan/vlan containers, from Hangbin Liu.

   - Endainness fixes in aqc111, from Oliver Neukum.

   - Handle errors in packet_init properly, from Haibing Yue.

   - Various W=1 warning fixes in kTLS, from Jakub Kicinski"
