Detailed Description

struct fw_cdev_send_phy_packet - send a PHY packet : Passed back to userspace in the PHY-packet-sent event : First and second quadlet of the PHY packet : The bus generation where packet is valid

The FW_CDEV_IOC_SEND_PHY_PACKET ioctl sends a PHY packet to all nodes on the same card as this device. After transmission, an FW_CDEV_EVENT_PHY_PACKET_SENT event is generated.

The payload [] shall be specified in host byte order. Usually, [1] needs to be the bitwise inverse of [0]. VersaPHY packets are an exception to this rule.

The ioctl is only permitted on device files which represent a local node.
