New Revision: 209144
URL: http://svn.freebsd.org/changeset/base/209144

Log:
  - Because hostapd calls iv_key_set() before if_init(), make sure key_set
    callback function will be executed, and that the key won't be deleted during
    the init process.
  - txmic and rxmic are written into the chip the same place regardless of
    opmode.
  - Make the hardware generate 802.11 sequence numbers.
