No AP found using v5.6.4.2/v5.6.4.1

[yshui]

A scan shows no results. If I downgrade to v5.3.4, I can see the APs and I can connect to them just fine.

In dmesg, I see lines like:

RTW: _alloc_mgtxmitframe(wlan0) alloc xmitbuf fail

Not sure if they are related.

@epinter I don't think #504 is related, my VID:PID is 2357:011e

Looks like this problem has disappeared from the latest v5.6.4.2 branch. Closing.
