Usage of __packed seems incorrect since this is not an ABI buffer, and 
packing will potentially result in some members being unaligned (ath11k 
has struct ath11k_skb_cb packed as well).

Suggest removing __packed and using pahole to find the ideal layout 
since the only concern is that this does not exceed 
IEEE80211_TX_INFO_DRIVER_DATA_SIZE
