New Revision: 298948
URL: https://svnweb.freebsd.org/changeset/base/298948
Log:
[bwn] break out the 'g' phy code into a separate source file.
* Break out the 'g' phy code;
* Break out the debugging bits into a separate source file, since
some debugging prints are done in the phy code;
* Make some more chip methods in if_bwn.c public.
This brings the size of if_bwn.c down to 6,805 lines which is now
approaching managable.
