[PATCH] pktcdvd: Allow larger packets
The pktcdvd driver uses a compile time macro constant to define the maximum
supported packet length. I changed this from 32 sectors to 128 sectors
because that allows over 100 MB of additional usable space on a 700 MB cdrw,
and increases throughput.
Note that you need a modified cdrwtool program that can format a CDRW disc
with larger packets to benefit from this change.
