* For transmit packets, the header length must be a multiple of 4 and specifies
* the numbers of bytes in @header that will be prepended to the packet's
* payload; these bytes are copied into the kernel and will not be accessed
* after the ioctl has returned. The sy and tag fields are copied to the iso
* packet header (these fields are specified by IEEE 1394a and IEC 61883-1).
* The skip flag specifies that no packet is to be sent in a frame; when using
* this, all other fields except the interrupt flag must be zero.
*
* For receive packets, the header length must be a multiple of the context's
* header size; if the header length is larger than the context's header size,
* multiple packets are queued for this entry. The sy and tag fields are
* ignored. If the sync flag is set, the context drops all packets until
* a packet with a matching sy field is received (the sync value to wait for is
* specified in the &fw_cdev_start_iso structure). The payload length defines
* how many payload bytes can be received for one packet (in addition to payload
* quadlets that have been defined as headers and are stripped and returned in
* the &fw_cdev_event_iso_interrupt structure). If more bytes are received, the
* additional bytes are dropped. If less bytes are received, the remaining
* bytes in this part of the payload buffer will not be written to, not even by
* the next packet, i.e., packets received in consecutive frames will not
* necessarily be consecutive in memory. If an entry has queued multiple
* packets, the payload length is divided equally among them.
*
* When a packet with the interrupt flag set has been completed, the
* &fw_cdev_event_iso_interrupt event will be sent. An entry that has queued
* multiple receive packets is completed when its last packet is completed.
