Hi, everyone!

I've been trying to connect to a WPA3 (personal, not enterprise)
network but, as expected, the connection always fails with hardware
encryption (most likely due to mandatory MFP, which the hardware won't
do). What I didn't expect was to have the exact same problem when
using software crypto. I've tried with other devices, and they work
fine. One thing I noticed is this: for example, a Ralink RT2790
device, on another machine, shows the following supported cyphers with
hardware crypto…

        * WEP40 (00-0f-ac:1)
        * WEP104 (00-0f-ac:5)
        * TKIP (00-0f-ac:2)
        * CCMP-128 (00-0f-ac:4)
        * CCMP-256 (00-0f-ac:10)
        * GCMP-128 (00-0f-ac:8)
        * GCMP-256 (00-0f-ac:9)

… and with software crypto…

        * WEP40 (00-0f-ac:1)
        * WEP104 (00-0f-ac:5)
        * TKIP (00-0f-ac:2)
        * CCMP-128 (00-0f-ac:4)
        * CCMP-256 (00-0f-ac:10)
        * GCMP-128 (00-0f-ac:8)
        * GCMP-256 (00-0f-ac:9)
        * CMAC (00-0f-ac:6)
        * CMAC-256 (00-0f-ac:13)
        * GMAC-128 (00-0f-ac:11)
        * GMAC-256 (00-0f-ac:12)

… while b43 shows exactly the same in both modes…

        * WEP40 (00-0f-ac:1)
        * WEP104 (00-0f-ac:5)
        * TKIP (00-0f-ac:2)
        * CCMP-128 (00-0f-ac:4)
        * CCMP-256 (00-0f-ac:10)
        * GCMP-128 (00-0f-ac:8)
        * GCMP-256 (00-0f-ac:9)

This is a BCM4318 device (PCI ID 14e4:4318), but I don't know if
that's relevant.
Is this behaviour expected?

Thanks in advance,
Rui
