This series adds userspace support for vendor HCI packets, which use
0xff as their packet type, complementing the kernel change here:
https://lore.kernel.org/all/20260830-btusb_qcc2072-v2-2-5c0e0c9dd98b@oss.qualcomm.com
All commits are straightforward.
---
Changes in v2:
- Rename BT_RCV_VENDOR_PKT to BT_RECV_VENDOR_PKT
- Improve the commit title and message
- Link to v1: https://patch.msgid.link/20260719-vendor_hci-v1-0-df2ac5a50117@oss.qualcomm.com
