The driver_stats file contains general driver statistics. There is one numbered
subdirectory per TrueScale device on the system. Each numbered subdirectory
contains the following per-device files:
• port1counters
• port2counters
• flash
The driver1counters and driver2counters files contain counters for the
device, for example, interrupts received, bytes and packets in and out, etc. The
flash file is an interface for internal diagnostic commands.
The file counter_names provides the names associated with each of the counters
in the binary port#counters files, and the file driver_stats_names provides the
names for the stats in the binary driver_stats files.
