Even when I do an "iw xxx scan trigger", scan_request->nr_ssids
is always 1 in my driver.
Is this a bug or a feature?
However, scan_request->ssids[0].ssid_len is 0.
So to ask my firmware for an SSID scan, I need to do
if (req->n_ssids && req->ssid[0].ssid_len)
instead of simply
if (req->n_ssids)

No. You need to ask it to probe for the wildcard SSID, which is 0 bytes
long.
