Subject: [PATCH] mac80211: mesh: drop frames appearing to be from us
|
|
|
|
If there are multiple mesh stations with the same MAC address,
|
|
they will both get confused and start throwing warnings.
|
|
|
|
Obviously in this case nothing can actually work anyway, so just
|
|
drop frames that look like they're from ourselves early on.
