From 48a847709f821b5eecd45ae7660add1869f9cd37 Mon Sep 17 00:00:00 2001 From: Henrik Brix Andersen Date: Tue, 14 Feb 2006 09:09:52 +0800 Subject: [PATCH] ipw2200: print geography code upon module load Given the amount of support requests for the meaning of the geography code I've written a patch for printing this information on module load no matter the debug level. I've also added a section to the README.ipw2200 file listing the geography codes and their meaning. Signed-off-by: Henrik Brix Andersen Signed-off-by: Zhu Yi Signed-off-by: John W.
