[PATCH 0/2] wifi: rtw88: USB fixes

[Sascha Hauer]

This series addresses issues for the recently added RTW88 USB support
reported by Andreas Henriksson and also our customer.

The hardware can't handle urbs that have a size of multiple of the
bulkout_size (usually 512 bytes). The symptom is that the hardware
stalls completely. The issue can be reproduced by sending a suitably
sized ping packet from the device:

ping -s 394 <somehost>

(It's 394 bytes here on a RTL8822CU and RTL8821CU, the actual size may
differ on other chips, it was 402 bytes on a RTL8723DU)

Other than that qsel was not set correctly. The sympton here is that
only one of multiple bulk endpoints was used to send data.
