- 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.
