thanks to stefan's guidance, i've looked up the PMF support in the
rsncap field in the output of

# tcpdump -n -i iwx0 -y IEEE802_11_RADIO -v type mgt and subtype beacon

my MSM430 is too old to support WPA3, but i've been able to test it
against a Freebox (french ISP CPE) v8 'pop' running freebox os 4.9 where
the available settings are:

- WPA3 -> rnscap = 0xcc -> PMF required ?
- WPA2/3 transition -> rsncap = 0x8c -> PMF optional ?
- WPA2/3 compatibility (recommended) -> rsncap = 0xc -> no PMF ?

when the Freebox is configured on WPA2/3 transition, i can still connect
with:
- amd64 t495s

iwm0: hw rev 0x320, fw ver 46.7e3e4b69.0
