Hi,

I was just trying to make iwlwifi work again with tx info in skb->cb,
but am running into something I don't understand:

What is a TFD, and why can it have multiple SKBs with a single tx
status? I'm referring to:

/* One for each TFD */
struct iwl3945_tx_info {
	struct ieee80211_tx_status status;
	struct sk_buff *skb[MAX_NUM_OF_TBS];
};

I would have expected something like this with 4965 that has aggregation
support (and aggregation is reported just once) but here? Confused.

johannes
