[RFC] ath10k: use raw tx

[Yeoh Chun-Yeow]

Hi, all

Did anyone try the raw tx on adhoc mode? I have tested this patch with
firmware 999.999.0.636.

The unicast frame is not transmitted using raw tx, only broadcast.

After adjust the cmd_tx.len as follow, I have managed to make the
adhoc STA to ping each others.

skb_cb->htt.txbuf->cmd_tx.len = __cpu_to_le16(msdu->len -
sizeof(struct ieee80211_hdr_3addr) + sizeof(struct ethhdr));

Can someone comment on this?
