From: Johannes Berg Date: Thu, 6 May 2010 19:21:40 +0000 (-0700) Subject: iwlwifi: use proper short slot/preamble settings X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c213d745b25b24b68f790fe55fc0a2159218a079;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: use proper short slot/preamble settings The short preamble setting might change on the fly, and then we already use the right mac80211 variable. However, in other places we don't, which is especially wrong in the AP code since in that case the assoc_capability is invalid. Also, the IBSS special case is not needed since "use_short_slot" will be properly cleared, but the "assoc_capability" might be invalid (which must be the reason for the special case).
