Hi Mark, > Mediatek Bluetooth controller sends the FW log and FW dump via EP2. > This patch creates an MTK specified callback(btusb_recv_acl_mtk) to > replace the original one (hci_recv_frame) when an MTK controller is > detected. The new callback will separate the firmware dump traffics > from the ACL data to have them process separately. > > 1. Add a new field (recv_acl) to the btusb_data struct to store > vendor-specific ACL callback handler. > 2. Add the MTK-specific ACL callback handler (btusb_recv_acl_mtk) to > process ACL data, debug log, and firmware dump. > 3. The debug log traces LMP/LL events and connection quality reports. > 4. The upper layer can use hci_channel_monitor to receive these > packets. > > Example btmon: firmware debug log. > 1. Enable firmware debug log. > < HCI Command: Vendor (0x3f|0x005d) plen 4 > 00 00 02 02 .... >> HCI Event: Command Complete (0x0e) plen 8 > Vendor (0x3f|0x005d) ncmd 1 > Status: Success (0x00) > 00 00 02 02 .... > 2.
