The only + parameter is the neighbor ID. If you want to list all the neighbors in a + table, start with nid=0, and keep incrementing nid until you get a + "(null)" string. Note that the nid from a fwt_list_route command can be + used as an input to this command. Also note that this command is meant + mostly for debugging. It is expected that users will use fwt_lookup. + One important reason for this is that the neighbor id may change as the + neighbor table is altered. + + iwpriv ethX fwt_list_neigh nid + + The output is a string of the following form: + + ra sleepmode snr references + + where the different fields are:- + ra -- RA MAC address (in the form "00:11:22:33:44:55") + sleepmode -- RA's sleep mode (currently unused) + snr -- SNR in the link to RA (currently unused) + references -- RA's reference counter + +fwt_reset + This command is used to reset the FWT table, getting rid of all the + entries. There are no input parameters. + + iwpriv ethX fwt_reset + + The command does not return anything. + +fwt_cleanup + This command is used to perform user-based garbage recollection. The + FWT table is checked, and all the entries that are expired or invalid + are cleaned. Note that this is exported to the driver for debugging + purposes, as garbage collection is also fired by the firmware when in + space problems. There are no input parameters. + + iwpriv ethX fwt_cleanup + + The command does returns the number of invalid/expired routes deleted. + +fwt_time + This command returns a card's internal time representation. It is this + time that is used to represent the expiration times of FWT entries. The + number is not consistent from card to card; it is simply a timer count. + The fwt_time command is used to inspect the timer so that expiration + times reported by fwt_list can be properly interpreted. + + iwpriv ethX fwt_time + +mesh_get_ttl + + The mesh ttl is the number of hops a mesh packet can traverse before it + is dropped. This parameter is used to prevent infinite loops in the + mesh network. The value returned by this function is the ttl assigned + to all mesh packets. Currently there is no way to control the ttl on a + per packet or per socket basis. + + iwpriv ethX mesh_get_ttl + +mesh_set_ttl ttl + + Set the ttl.
