This is a code re-write. ic->raw_xmit need a pointer to ieee80211_node for the destination node (da). I have reorganized the code so that a pointer to the da node is searched for in the end & in one place. * Make mesh_find_txnode public to be used by HWMP, renamed to ieee80211_mesh_finx_txnode; * changed the argument from ieee80211_node to ieee80211vap for all hwmp_send_* functions; * removed the 'sa' argument from hwmp_send_* functions as all HWMP frames have the source address equal to vap->iv_myaddr; * Modified hwmp_send_action so that if da is MULTCAST ni=vap->iv_bss otherwise we called ieee80211_mesh_find_txnode. Also no need to hold a reference in this functions if da is not MULTICAST as by finding the node it became referenced in ieee80211_find_txnode; Approved by: adrian (mentor)
