[PATCH RFC v2 0/3] Bluetooth: Add generic support for vendor HCI frames

Hi Luiz
To address the below concerns you raised on previous
discussion.

- Not use safer skb helper like skb_pull_data()
- It will skip sending to the monitor, making debugging much harder

Looking forward to your further comments.
