From: Ron Rindjunsky Date: Thu, 12 Jun 2008 01:46:55 +0000 (+0800) Subject: iwlwifi: map sw and hw ampdu queues X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7f3e4bb60f81dd172d5e4b89220cb3f80c6dc552;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: map sw and hw ampdu queues This patch maps sw and hw queues (for aggregations), so the right mac80211 queue will be waken when ieee80211_wake_queue is invoked.
