svn commit: r187488 - user/sam/wifi/sys/net80211

[Sam Leffler]

New Revision: 187488
URL: http://svn.freebsd.org/changeset/base/187488

Log:
  Extend channel definition with:
  o max antenna gain
  o driver private opaque data
  
  Note this grows the size of a channel to 16 bytes (1 byte unallocated);
  which makes the default channel table 4Kbytes (up from 3Kbytes).  The
  driver private data might be shrunk to a byte.
