hi
I noticed buffalo-tag fix and mkwsrimg can be used for some other
Buffalo WxR products too.
(probably. I just checked some of official update images for now)
if this patch is not merged yet, I want to make v3 patch ASAP to do
some more cosmetic changes (e.g. s/WSR/WxR/).
if it's too late, I'll make new patch later.
Regards,
