Maybe someone at OpenWrt (with edit access to the Wiki and such) could write a simple script for git send-email with a wrapper for the [PATCH] [architecture] what subject and Signed-off-by thing. Would speed things up quite a bit imho, especially for newcomers. I see quite a few "not formatted properly" rejections.
It is up to you to put "[architecture] what" into your commit message. Signed-off-by is a legal procedure, it should not be automated, you should do "git commit --signoff" yourself. "[PATCH]" is added by "git send-email".
If you don't want to setup your client properly and keep using some GUI or Web client, you can format your patch with "git format-patch" and submit whatever files it produces.
OpenWrt rightfully expects you to read at least "man giteveryday", which is titled "A useful minimum set of commands for Everyday Git" and includes "format-patch" and "send-email" in "INDIVIDUAL DEVELOPER (PARTICIPANT)" section.
Signed-off-by is automatically added to commits if you add "-s" to the git commit command. In addition, git format-patch (and thus git send-email) already adds [PATCH X/Y] to the subject line (prepended to the short commit message).
Ah, thanks. If I only had known! :)
