commit b1e8102a4048003097c7054cbc00bbda91a5ced7 upstream
Commit 6b3e87cc0ca5 ("iwlwifi: Add support for LARI_CONFIG_CHANGE_CMD cmd v9") added a few bits to iwl_lari_config_change_cmd::oem_unii4_allow_bitmap if the FW has LARI version >= 9. But we also need to send those bits for version 8 if the FW is capable of this feature (indicated with capability bits) Add the FW capability bit, and set the additional bits in the cmd when the version is 8 and the FW capability bit is set.

I didn't want to alter the commit log of this patch, but this patch has a bigger impact that just enabling a feature in the firmware. It checks that the firmware actually supports that feature and this fixes crashes that were reported on certain device / platform combinations that made wifi unusable.
