Author: avos Date: Sat Feb 18 19:19:08 2017 New Revision: 313921 URL: https://svnweb.freebsd.org/changeset/base/313921 Log: MFC r313694: iwi: add 12-14 2GHz channels into channel list. Return full channel list via iwi_getradiocaps() method (ieee80211_init_channels() was replaced with iwi_getradiocaps() to be consistent with other drivers).
