Dear all,
I found this question raised in the mail list, which also interests
me, prior to my registration.
I am trying to do something similar as Bruno suggested, using
ath5k_tx_queue() or ath5k_tx() to transmit a packet in the ath5k
layer.
However, I am currently troubled with how to prepare a complete WLAN
packet from scratch.
Could anyone please advise? Thanks in advance.
Best Regards
YY

Hi, all
I'm a student at NYU and I'm very interested in ath5k driver code.
What I'm trying to do now is to make the ath5k broadcast my own "hello
packet" every 3 sec.
I've successfully put a timer in the ath5k_attach() function, and it works
good.
Next, I put ieee80211_subif_start_xmit(skb, dev) in the timer.
Here comes the problem. The ieee80211_subif_start_xmit(skb, dev) wants the
struct net_device *dev, but in ath5k_attach we only have struct ieee80211_hw
*hw.
I dont konw where to get the struct net_device *dev.
Is anyone can help me?
Plz~~~~~
Thank you very much
BEST

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.
