[PATCH 1/2] vendor_quirks: add PMKID mismatch quirk

[Jan-Henrik Bruhn <git@jhbruhn.de>]

From: Jan-Henrik Bruhn <kernel@jhbruhn.de>

pmkid_mismatch:
  Extreme Networks APs running WiNG include a PMKID in message 1/4
  of the FT-8021X 4-way handshake which does not match any PMKID IWD
  derives, even directly after a full EAP authentication. This quirk
  is intended to relax the PMKID check for these APs. They are
  identified by the Zebra Technologies OUI in their vendor IE.
