Selection between different station and access point (AP) modes.
Station modes:
station - Basic station mode. Find and connect to acceptable AP.
station-wds - Same as station, but create WDS link with AP, using proprietary extension. AP configuration has to allow WDS links with this device. Note that this mode does not use entries in wds.
station-pseudobridge - Same as station, but additionally perform MAC address translation of all traffic. Allows interface to be bridged.
station-pseudobridge-clone - Same as station-pseudobridge, but use station-bridge-clone-mac address to connect to AP.
AP modes:
ap-bridge - Basic access point mode.
bridge - Same as ap-bridge, but limited to one associated client.
wds-slave - Same as ap-bridge, but scan for AP with the same ssid and establishes WDS link. If this link is lost or cannot be established, then continue scanning. If dfs-mode is radar-detect, then APs with enabled hide-ssid will not be found during scanning.
Special modes:
alignment-only - Put the interface in a continuous transmit mode that is used for aiming the remote antenna.
nstreme-dual-slave - allow this interface to be used in nstreme-dual setup.
MAC address translation in pseudobridge modes works by inspecting packets and building a table of corresponding IP and MAC addresses. All packets are sent to AP with the MAC address used by pseudobridge, and MAC addresses of received packets are restored from the address translation table. There is a single entry in the address translation table for all non-IP packets, hence more than one host in the bridged network cannot reliably use non-IP protocols. Note: Currently IPv6 doesn't work over Pseudobridge
