transmission of the frame.
Single Collision
The total number of successfully transmitted frames that experienced exactly one
collision.
Multiple Collision
The total number of successfully transmitted frames that experienced more than one
collision.
Maximum Collision
The number of frames dropped in the transmit GMAC because the frame experienced
16 consecutive collisions.
