Subject: [PATCH] iwlwifi: mvm: Invert the condition for OFDM rate
Git-commit: d558b7f834707b6acdfd3f91c8524598db8456f0
Patch-mainline: v5.5-rc1
References: jsc#SLE-13430
OFDM rate used for all bands except to band 2.4 which use CCK rate.
Inverting the condition help that in future we won't need to expand the
condition for more bands.
