dot3StatsExcessiveTransmissions (offset: 0x82C)
A count of frames for which transmission on a particular interface fails due to excessive collisions.
dot3StatsLateCollisions (offset: 0x830)
The number of times that a collision is detected on a particular interface later than 512 bit-times into the
transmission of a packet.
iHCOutUcastPkts (offset: 0x86C)
The number of packets that higher-level protocols requested be transmitted, and that were not addressed to a
multicast or broadcast address at this sublayer, including those that were discarded or not sent.
iHCOutMulticastPkts (offset: 0x870)
The number of packets that higher-level protocols requested be transmitted, and that were addressed to a
multicast address at this sublayer, including those that were discarded or not sent.
iHCOutBroadcastPkts (offset: 0x874)
The number of packets that higher-level protocols requested be transmitted, and that were addressed to a
broadcast address at this sublayer, including those that were discarded or not sent.
ifCRSERRORS (offset: 0x878)
The number of packets that have CRS errors.
iOUTDISCARDS (offset: 0x87C)
The number of packets that are discarded.
H2B Statistics Registers
There are two sets of H2B Statistics registers – though both sets are accessible from Host as well as APE, each
side shall own a set. Set1 is owned by Host Driver and Set2 is owned by APE. HTX2B Stats Registers resides
in TX-MAC and the B2HRX Stats Registers reside in RDI. A counter is automatically reset to 0 by HW upon a
Read Operation by software. All counters roll over.
