You need to create a writable file in debugfs. As an example, look at
debugfs_netdev.c for the "tsf" file. When you write to the file from
userspace, you would then update some (new) battery level variable that
you store in either the struct ieee80211_local or struct
ieee80211_sta_info (depending on if this is the battery level for
_this_ device or for the one we're talking to).
mesh_hwmp.c will compute the airtime link metric when it needs it just like
it does currently.
Hopefully that is enough of a blueprint to go on.
