wifi: mac80211: split mesh fast tx cache into local/proxied/forwarded
[ Upstream commit 8c75cdcdf869acabfdc7858827099dcde9f24e6c ]
Depending on the origin of the packets (and their SA), 802.11 + mesh headers
could be filled in differently. In order to properly deal with that, add a
new field to the lookup key, indicating the type (local, proxied or
forwarded). This can fix spurious packet drop issues that depend on the order
in which nodes/hosts communicate with each other.
