It's certainly not a regression, no. I'm running extensive stress-tests
with this driver. Then I guess adding the following to the commit log
should suffice?

"Note that this patch doesn't fix a bug that was observed. The change is
merely done for the sake of completeness as the hardware supports
appending IEs in scans. Tests show that network scans work fine with
this patch applied."
