From: "Luis R. Rodriguez" <[e-mail]>

This enables the capability to enable cellular base station
regulatory hint support to ath5k, ath9k, ath9k_htc and carl9170.

This adds a URL for documentation / reference. Other drivers
should consider doing the same.

+	  regulatory hint support onto either or these drivers:
