Ack/+1,
It's not the last fix for 'delba' unfortunately :(
Next lines should use delba as u8 if I see correctly
See rtllib_DELBA() (line 141) - It first fills skb with rtllib_hdr_3_addr,
and then adds skb delbaparam_set and reasonCode (as a 6 bytes).
Or I'm tired - will re-check tomorrow.
All this pointer math would have worked if "delba" were a void pointer,
but that's a bit ugly. Anyway, I'll send a proper fix for this.
Looks like it should be u8.
This is a complete hash of modifying a 3 address header.
However, in kernel struct ieee80211_mgmt has a delba entry to replace
the entire header.
