Iso reception: Use packet timestamps in juju ABI v2
In the firewire-cdev ABI v1, the kernel exported only the timestamp
of interrupt packets. libraw1394 estimated the cycle of all packets
between interrupt packets by continuously incrementing the cycle.
In v2 of the ABI, we can obtain an accurate timestamp of each packet
as provided by the OHCI controller. AFAIU, this is also what you got
from raw1394/ ohci1394.
