Subject: [PATCH 05/10] rtlwifi: enable mac80211 fast-tx support
Date: Wed, 10 Jan 2018 13:19:57 +0800 [thread overview]
Message-ID: <20180110052002.9544-6-pkshih@realtek.com> (raw)
In-Reply-To: <20180110052002.9544-1-pkshih@realtek.com>
From: Ping-Ke Shih <pkshih@realtek.com>
To enable the mac80211 fast-tx feature, the hw/driver needs to support
dynamic power saving and fragmentation. Since our driver does not
need to fragment packet into smaller pieces, we just hook an empty
callback of set_frag_threshold to avoid fragmentation in mac80211.
After this, the mac80211 will not fragment the packets and can transmit
them faster by cache the header information.
