Subject: iwlwifi: dvm: don't enable CTS to self
From: Emmanuel Grumbach <[email protected]>
commit 43d826ca5979927131685cc2092c7ce862cb91cd upstream.
We should always prefer to use full RTS protection. Using
CTS to self gives a meaningless improvement, but this flow
is much harder for the firmware which is likely to have
issues with it.
