There should be a beta firmware with the crash fixed...
But anyway the ct firmware doesn't work with offload and
this is the main reason i never actually put effort in getting
this merged. Openwrt use ath10k-ct and offload doesn't work,
the dev didn't bother to fix it so.... rip any use of this since the
original ath10k is not usable for some user.
