LE Set Default PHY.
The description below is extracted from Core_v5.4, Vol 4, Part E, Section 7.8.48
The HCI_LE_Set_Default_PHY command allows the Host to specify its preferred values for the transmitter PHY and receiver PHY to be used for all subsequent connections over the LE transport.
The All_PHYs parameter is a bit field that allows the Host to specify, for each direction, whether it has no preference among the PHYs that the Controller supports in a given direction or whether it has specified particular PHYs that it prefers in the TX_PHYs or RX_PHYs parameter.
The TX_PHYs parameter is a bit field that indicates the transmitter PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the TX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.
The RX_PHYs parameter is a bit field that indicates the receiver PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the RX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.
If the Host sets, in the TX_PHYs or RX_PHYs parameter, a bit for a PHY that the Controller does not support, including a bit that is reserved for future use, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).
If the Controller does not support asymmetric connections (see [Vol 6] Part B, Section 4.6.9.1) and the Host sets All_PHYs to 0x00 and TX_PHYs to a different value than RX_PHYs, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).
Event(s) generated (unless masked away): When the HCI_LE_Set_Default_PHY command has completed, an HCI_Command_Complete event shall be generated.
