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.
