Bluetooth: Implement PHY changed event
This defines and implement phy changed event and send it to user whenever selected PHYs changes using SET_PHY_CONFIGURATION. This will be also trigerred when BREDR pkt_type is changed using the legacy ioctl HCISETPTYPE. @ MGMT Command: Set PHY Configuration (0x0045) plen 4 Selected PHYs: 0x7fff BR 1M 1SLOT BR 1M 3SLOT BR 1M 5SLOT EDR 2M 1SLOT EDR 2M 3SLOT EDR 2M 5SLOT EDR 3M 1SLOT EDR 3M 3SLOT EDR 3M 5SLOT LE 1M TX LE 1M RX LE 2M TX LE 2M RX LE CODED TX LE CODED RX < HCI Command: LE Set Default PHY (0x08|0x0031) plen 3 All PHYs preference: 0x00 TX PHYs preference: 0x07 LE 1M LE 2M LE Coded RX PHYs preference: 0x07 LE 1M LE 2M LE Coded > HCI Event: Command Complete (0x0e) plen 4 LE Set Default PHY (0x08|0x0031) ncmd 1 Status: Success (0x00) @ MGMT Event: Command Complete (0x0001) plen 3 Set PHY Configuration (0x0045) plen 0 Status: Success (0x00) @ MGMT Event: PHY Configuration Changed (0x0026) plen 4 Selected PHYs: 0x7fff BR 1M 1SLOT BR 1M 3SLOT BR 1M 5SLOT EDR 2M 1SLOT EDR 2M 3SLOT EDR 2M 5SLOT EDR 3M 1SLOT EDR 3M 3SLOT EDR 3M 5SLOT LE 1M TX LE 1M RX LE 2M TX LE 2M RX LE CODED TX LE CODED RX Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
