I think it's a trade off between performance optimization and clean interface. As we already use dev_alloc_skb to reserve 32 bytes headroom, it should be enough for most of the current drivers. While for those drivers really need a bigger extra headroom and support Rx aggregation, this probably means ieee80211_skb_resize. But the resize should always happen for every packet from the IP stack, right?
