Why are you running half-duplex connections that would require
collisions?  Full-duplex ethernet has worked pretty well since it was
standardized in 1998.  And even if you were running half-duplex
connections, why would you care about a flow-control method?  The myth
that collisions were bad has been thoroughly debunked now that there are
no token-ring sales-weasels[1] to stir the pot every now and again.

But, if the device is going to support the counters, it would be in the
ETHERLIKE-MIB, with symbolic names of:
dot3StatsSingleCollisionFrames,
dot3StatsMultipleCollisionFrames,
dot3StatsExcessiveCollisions,
dot3StatsLateCollisions,

friendly rodents.
