I was afraid that might happen. This means skb->cb is not large
enough to hold both the qdisc and the ieee80211 structs.
Just for testing, changing (include/net/mac80211.h):
#define IEEE80211_TX_INFO_DRIVER_DATA_SIZE \
(sizeof(((struct sk_buff *)0)->cb) - 8)
to
#define IEEE80211_TX_INFO_DRIVER_DATA_SIZE \
(sizeof(((struct sk_buff *)0)->cb) - 12)
might help to get it to compile. If that doesn't work, try -16.
That didn't work, neither with -12 or -16.
I'll give it a try myself, please wait a few minutes.
We can't fit them into the cb together, I don't see a way to
shrink ieee80211_tx_info.
Maybe one of the wireless folks can suggest something? Is it
really necessary to pass the full struct ieee80211_tx_info
through the qdisc layer, or could the struct be split? It
needs to find a way to co-exist peacefully with qdiscs'
skb->cb usage.
