The reason for this flag was to reduce host CPU load for frame aggregation (merging multiple frames (skb's) into one frame. It was used to implement one part of Atheros Super A/G enhancements, but I don't see those proprietary changes being generic enough to be worth adding into net/d80211. However, IEEE 802.11n has similar features that may indeed benefit from this flag. As such, I would not remove it. -- Jouni Malinen PGP id EFC895FA
