-Subject: [PATCH] mesh: make forwarding configurable
-To: hostap@lists.infradead.org
-Cc: Jouni Malinen <j@w1.fi>,
- Johannes Berg <johannes.berg@intel.com>
-
-Allow mesh_fwding to be specified in a mesh bss config, pass that
-to the driver (only nl80211 implemented for now) and announce
-forwarding capability accordingly.
