[Andriy Voskoboinyk]

Author: avos
Date: Thu May 26 15:05:37 2016
New Revision: 300748
URL: https://svnweb.freebsd.org/changeset/base/300748

Log:
  run: switch to ieee80211_add_channel_list_*()
  
  - Use device's channel list instead of default one (from
  ieee80211_init_channels()).
  - Add ic_getradiocaps() method.
