Stop a mesh STA from flooding with peer frames.
This problem happens when using ACL policy to filter mesh STA
but two nodes have different policy. Then one of them will try to
peer all the time. This can also help if for any reason one of the
peering mesh STA have problems sending/receiving peer frames.
* Modified struct ieee80211_node to include two new fields:
+ struct callout ni_mlhtimer /* link mesh backoff timer */
+ uint8_t ni_mlhcnt /* link mesh holding counter */
* Added two new sysctl (check sysctl -d for more info):
+ net.wlan.mesh.backofftimeout=5000
+ net.wlan.mesh.maxholding=2;
* When receiving a beacon and we are in IEEE80211_NODE_MESH_IDLE
check if ni_mlhcnt >= ieee80211_mesh_maxholding, if so do not do anything;
* In mesh_peer_timeout_cb when transitioning from IEEE80211_NODE_MESH_HOLDING
to IEEE80211_NODE_MESH_IDLE increment ni_mlhcnt, and eventually start
ieee80211_mesh_backofftimeout;
