I wrote that awk script years ago so that we could get rid of the
old hard-coded rulesets and so I could have something working in RHEL5.

I never merged the DFS CAC stuff in wireless-regdb, because of the
unresolved issue of supporting multiple formats.  It looks to me like
the dfs_cac stuff in genregdb.awk is broken, since it doesn't seem
to account for flags.

I sent a patch that should account for the antenna gain issue.
Please give it a review.

Obviously, we need to talk more about this in Chicago if not before...
