Subject: [wireless] update old static regulatory domain rules
Message-id: <20091211190845.GA8923@redhat.com>
Patchwork-id: 21903
O-Subject: [RHEL5.5 PATH] wireless: update old static regulatory domain rules
Bugzilla: 543723

I recently discovered that the wireless regulatory rules in the
statically defined regulatory domains were out of date.  This patch (a
backport of one I'm queueing for upstream) updates the rules for "US"
and "JP", and points the fake "EU" domain at the safe "world roaming"
domain.  Note that this has no effect on iwl3945, iwlagn, ath5k, or
ath9k (which enforce their own rules either in the driver or in the
hardware itself) but it does influence the Ralink and Realtek drivers.
