Re: Intel Wi-Fi: scope of iwx(4) on FreeBSD

Hi.

For firmwares, IIUC, iwx seems to be sharing them with iwlwifi, looking
into its commit messages.

  https://cgit.freebsd.org/ports/commit/net/wifi-firmware-iwlwifi-kmod?id=ef3fa2a325a592baa6573782a72cf0d833589ffa

And looking into sys/dev/iwx/if_iwx.c in D49259, especially around the
definition of the array iwx_devices[] (struct iwx_devices) around line
217 (198 through 238 including #define's), only AX200, 201 and 211
including their variants seems to be supported.

And I don't have AX series of WiFi chips/cards, so cannot test.
