wifi: iwlwifi: mvm: rfi: disable RFI feature
This feature depends on a platform bugfix. Until we have a mechanism that can verify a platform has the required bugfix, disable RFI. Fixes: ef3ed33dfc8f ("wifi: iwlwifi: bump FW API to 77 for AX devices") Reported-by: Jeff Chua <jeff.chua.linux@gmail.com> Link: https://lore.kernel.org/linux-wireless/CAAJw_ZvZdFpw9W2Hisc9c2BAFbYAnQuaFFaFG6N7qPUP2fOL_w@mail.gmail.com/ Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
