Subject: iwlwifi: mvm: rs: revert changes to search cycle rules
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=31b204525a7f0decee85ec336d406c01c5411a5c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

iwlwifi: mvm: rs: revert changes to search cycle rules

Adding more options in the search cycle causes longer
search cycles with additional wondering off to non optimal Tx
configurations. Reduce the Tx configurations searched to
improve throughput in non optimal attenuations.
