From: Ping-Ke Shih <[email protected]> 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.
