This should be CONFIG_DRIVER_MACSEC_NV to be consistent with the
previously used build defines.

Is this specific to only hostapd side? Or would this work with
wpa_supplicant as well?

What is that header file and where does one get it? I was not able to
compile this because of that file missing and if this line is commented
out, there were undefined structures and I could not find definitions
for those anywhere.


PS.

It is somewhat inconvenient if there is a large number of incompatible
kernel interfaces for setting up similar functionality. Is there a good
reason for not trying to use the upstream kernel interface for MACsec
and extend it as needed?
