I mentioned cooked monitor because putting the hw in monitor mode may not always be desirable, and cooked monitor bypasses that. You can send the AMSDU while you're connected. mac80211 treats injected frames that match the address of a local interface similar to regular tx on that interface, except for bypassing the normal 802.11 header encapsulation, so it should work for your tests. - Felix -- 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
