Bluetooth: Implement secondary advertising on different PHYs
This patch adds support for advertising in primary and secondary channel on different PHYs. User can add the phy preference in the flag based on which phy type will be added in extended advertising parameter would be set. @ MGMT Command: Add Advertising (0x003e) plen 11 Instance: 1 Flags: 0x00000200 Advertise in CODED on Secondary channel Duration: 0 Timeout: 0 Advertising data length: 0 Scan response length: 0 < HCI Command: LE Set Extended Advertising Enable (0x08|0x0039) plen 2 Extended advertising: Disabled (0x00) Number of sets: Disable all sets (0x00) > HCI Event: Command Complete (0x0e) plen 4 LE Set Extended Advertising Enable (0x08|0x0039) ncmd 2 Status: Success (0x00) < HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036) plen 25 Handle: 0x00 Properties: 0x0000 Min advertising interval: 1280.000 msec (0x0800) Max advertising interval: 1280.000 msec (0x0800) Channel map: 37, 38, 39 (0x07) Own address type: Random (0x01) Peer address type: Public (0x00) Peer address: 00:00:00:00:00:00 (OUI 00-00-00) Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00) TX power: 127 dbm (0x7f) Primary PHY: LE Coded (0x03) Secondary max skip: 0x00 Secondary PHY: LE Coded (0x03) SID: 0x00 Scan request notifications: Disabled (0x00) Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
