A couple of reasons: * WDS != 4addr [1], compatibility is a problem * you might not have admin control over given AP * given AP might not have 4addr as a config option in the first place * given AP might not be upgradable (for whatever reason) FWIW My IPv6 kernel patch was rejected by David[2]. I guess the next idea is to make a link device kernel driver in a similar fashion to bridge/macvlan and see if it gets a green light :) [1]: https://wiki.openwrt.org/doc/howto/clientmode [2]: https://www.spinics.net/lists/netdev/msg373426.html Michał _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
