Greenman, Gregory Nov. 2, 2022, 2:59 p.m. UTC 
From: Johannes Berg <johannes.berg@intel.com>

For Bz A-step hardware, the checksum offload is broken and
we need to use the old way, which is still there. Do that,
which requires taking the checksum capability bits out of
the IWL_DEVICE_BZ macro and listing them individually.
