You are using TKIP which is not yet supported for crypto offload
so either you
<br>
do not have hw_crypto enabled (which the newer firmware would) as
well or you
<br>
are not getting reasonable throughtput as ampdurx would be
automatically
<br>
disabled by LinuxKPI and it looks like from the next line of the
<br>
ifconfig output that it got (both RX and TX as it syas -ampdu; TX
is disabled
<br>

<br>
Do you have any chance to enable/switch to CCMP on the AP?
