Description of problem: When using the firewire stack to send iso packets, sending packets with a sy field other than 0 or 4, or a tag field other than 0 or 2 results in sending a packet with an incorrect sy or tag field. Version-Release number of selected component (if applicable): The 5.2 and 5.3beta kernels. How reproducible: Always. Steps to Reproduce: 1.Write a program that sends iso packets with varying sy and tag values. 2.Run it and observe the output with nosy or another firewire sniffer. 3.Observe that only the 2 bit of the tag field, and the 4 bit of the sy field ever change. Actual results: Only the 2 bit of the tag field, and the 4 bit of the sy field can be set in outgoing packets. Expected results: Both fields should be capable of taking all legal values. Additional info: This bug is in two parts: one (firewire-cdev.h) will require recompiling libraries and/or applications to fix. Since nobody has opened a bug report on this yet, it is apparent that such applications are rare.
