No, I guess you can do that. However, there are cases where the packet could potentially be reprocessed by mac80211, notably in the AP-side code for handling powersave clients (ieee80211_sta_ps_deliver_response). These code paths aren't executed for your driver right now, so this isn't really a concern, but if you plan on adding AP/GO support then it might be worth using a field inside skb->cb instead where you already have other fields. IOW, it's fine right now, but if you extend your code in the future you may run into hard to debug issues with it. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
