New Revision: 299792
URL: https://svnweb.freebsd.org/changeset/base/299792

Log:
  [bwn] Explicitly only work for SIBA parts; add some placeholder debugging.
  
  Set phy-full-init always to 1 for now; PHY-N supports being able to do
  partial init for things like fast channel changes but I'm going to
  ignore it all.
