Hi Felix Fietkau,

Very glad to your reply, it is highly important for us.
So far, we carefully read the Linux wireless stack(mac80211 subsystem). It really supports A-MSDU in mac80211 subsystem(the Linux wireless stack), however, the AMSDU is only supported on RX, and not on TX, and the call function for ieee80211_rx_h_amsdu() from net/mac80211/rx.c, does it?
Asking a detail issue as follows:
We want to know whether A-MSDU is opened by default in the Linux wireless stack or not? If A-MSDU can not be opened, how A-MSDU is opened by input several command?
WiFi A-MSDU is testing by Certification. Troubling that you can give us to a reply.


Thanks,
liuquancheng
