This patch introduces a new mesh configuration parameter "ht_opmode" and will allow user to check the current HT protection mode selected. Users could configure the protection mode by the command "iw mesh_iface set mesh_param mesh_ht_protection_mode=2". The default protection mode of mesh is set to non-HT mixed mode.
