pfifo_fast queue statistics

pfifo_fast queue statistics

[Systems Administrator]

LARTC Community,

I am using pfifo_fast and I would like to collect statistics from the
kernel, preferably via snmp, regarding packet drops from the 3 different
queues used by the pfifo_fast scheduler.  In the source code I see that
there is a counter for drops and overlimits [1], but it is unclear to me
if these counters are per queue or aggregate.  Can any one advise me?

Thanks for the great documentation and utilities!  Future thanks for any
advice.

Sincerely,
Dennison

qstats_drop_inc() function increments the qstats->drops variable.
