Hi Chris

Thanks for the patch.

However i have some stylistic issues with the patch. You seem to like
right justification of wrapped lines. I much prefer left.

Here i would prefer

debug_log(LOG_TYPE_WARN, "The newly added mac address (%s) "
"already exists on: %s\n",
mac_string, batman_if->dev);
debug_log(LOG_TYPE_WARN, "It is strongly recommended to "
"keep mac addresses unique avoid problems!\n");

Here i would put:
!(((struct batman_if *)if_list.next)->if_active ==
IF_TO_BE_ACTIVATED) &&

There is some tab/space issues here, but batman_if->dev); should be

Same comment as above.

This has already been fixed in linux-next. The code is going through
quite a lot of changes at the moment as part of the cleanup needed to
get out of stating. So i suggest you look at linux-next and not so
much as the latest -rc kernel, which is now somewhat out of date.

Here is a patch of how I think it should look like. With this
patch, the linux-next version of hard-interface.c is checkpatch.pl
clean. Is there anything i have missed? I will add the appropriate
headers and send it to GregKH sometime soon with my next batch of
patches for staging.

Thanks
Andrew
