Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:
 "Fixes keep trickling in:

  1) Various IP fragmentation memory limit hardening changes from Eric
     Dumazet.

  2) Revert ipv6 metrics leak change, it causes more problems than it
     fixes for now.

  3) Fix WoL regression in stmmac driver, from Jose Abreu.

  4) Netlink socket spectre v1 gadget fix, from Jeremy Cline"
