Adding an ipvlan link with the wireless device as the parent causes wifi to fail

[Mossop]

I have the TP-Link Archer TX20U Plus and for normal use have the adapter working and connecting to the wifi just fine. However attempting to add an ipvlan link on top of it with ip link add vlan0 link wlxf0a7314aaebc type ipvlan mode l2 bridge causes the wifi to stop working. If it was previously connected then all connectivity is lost. If it was not previously connected then wpa_supplicant reports a failure:

This is using the same config as without the ipvlan link so the key should still be correct.

I've tested doing the same with a different wifi adapter (a Qualcomm Atheros AR93xx) and it works just fine. Is this something that would need to be fixed in the driver?

It is beyond my capacity to add new features to this driver. Sorry
