Or well, at least I haven't figured out how to configure this without some kernel code changes. It would be kind of nice to get this working, but anyway, I made a small program for checking both unicast and broadcast communications for this type of use: hwsim_test from http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=tree;f=mac80211_hwsim/tools (it uses packet sockets bound to the interface and does not rely on the kernel IP stack) -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
