you are mixing layers here. ieee80211_subif_start_xmit() is a function of
mac80211 and you are in the ath5k driver code, so you can either just use
static int ath5k_tx_queue(struct ieee80211_hw *hw, struct sk_buff *skb,
struct ath5k_txq *txq)
directly, and give it a complete WLAN packet, including 802.11 headers and all
- or you but your timer somewhere else where you can access the net_device.
