Hi YuFan,<br>
<br>
Although there is code present in the qla2x00t-32gbit to support 16 Gb/s <br>
and older adapters, that support does not work properly. This is an <br>
issue that has been inherited from the equivalent upstream driver. <br>
Please use the qla2x00t driver for 16 Gb/s and older adapters.<br>
<br>
Thanks,<br>
<br>
Bart.<br>
