The WPA3 and Wi-Fi Enhanced Open Deployment Guide v1.1 (Table 4,
"SAE Groups") recommends that WPA3-Personal APs advertise support
for SAE groups 19, 20 and 21:
* group 19 - ECP 256-bit (NIST P-256)
* group 20 - ECP 384-bit (NIST P-384)
* group 21 - ECP 521-bit (NIST P-521)
hostapd's default is group 19 only, which leaves the two larger
ECP groups unavailable even though the peer may prefer them.
Set sae_groups = "19 20 21" as the default for any BSS whose
auth_type is sae or psk-sae (SAE, SAE Transition and SAE
Compatibility modes).
