Detailed Description

struct fw_cdev_event_phy_packet - A PHY packet was transmitted or received : See set by FW_CDEV_IOC_SEND_PHY_PACKET or FW_CDEV_IOC_RECEIVE_PHY_PACKETS ioctl : FW_CDEV_EVENT_PHY_PACKET_SENT or %..._RECEIVED : RCODE_..., indicates success or failure of transmission : Data length in bytes : Incoming data

If is FW_CDEV_EVENT_PHY_PACKET_SENT, is 0 and empty, except in case of a ping packet: Then, is 4, and [0] is the ping time in 49.152MHz clocks if is RCODE_COMPLETE.

If is FW_CDEV_EVENT_PHY_PACKET_RECEIVED, is 8 and consists of the two PHY packet quadlets, in host byte order.
