Hi! You can declare an mbuf tag and use that. Look at M_TXCB in net80211 and how mbuf tags are added. I've long thought about adding a net80211 mbuf tag to represent -all- of the tx related state - TX callback, rate control, rate completion, aggregation state, retry count, etc. That way all the drivers can use it. -adrian
