26.6.35 DMA Missed frame and buffer overflow counter register
The DMA maintains two counters to track the number of missed frames during reception.
This register reports the current value of the counter. The counter is used for diagnostic
purposes. Bits[15:0] indicate missed frames due to the host buffer being unavailable.
Bits[27:17] indicate missed frames due to buffer overflow conditions and runt frames
(good frames of less than 64 bytes) dropped by the MTL.
