I am not so sure.

RPi4 (BCM4345/6 - 7.45.234 (4ca95bb CY) FWID 01-996384e2)
        Supported extended features:
                * [ CQM_RSSI_LIST ]: multiple CQM_RSSI_THOLD records
                * [ 4WAY_HANDSHAKE_STA_PSK ]: 4-way handshake with PSK
in station mode
                * [ 4WAY_HANDSHAKE_STA_1X ]: 4-way handshake with
802.1X in station mode
                * [ DFS_OFFLOAD ]: DFS offload
                * [ SAE_OFFLOAD ]: SAE offload support
                * [ 4WAY_HANDSHAKE_AP_PSK ]: AP mode PSK offload support
                * [ SAE_OFFLOAD_AP ]: AP mode SAE authentication offload support

Jetson TX1 (BCM4354/1 - fw 7.35.349.104 (775a9ab CY) FWID 01-d55901b0):
        Supported extended features:
                * [ CQM_RSSI_LIST ]: multiple CQM_RSSI_THOLD records
                * [ DFS_OFFLOAD ]: DFS offload

So I have different brcmfmac HW reporting different features.

I don't get fwcap on either of the above devices:

ls /sys/kernel/debug/ieee80211/phy0/
fragmentation_threshold  ht40allow_map  long_retry_limit
rts_threshold  short_retry_limit
