P1TxGrpFrmCnt: This 16-bit counter reflects multicast and broadcast frames
transmitted without errors on port 1.
P2TxGrpFrmCnt: This 16-bit counter reflects multicast and broadcast frames
transmitted without errors on port 2.
P1TxUniFrmCnt: This 16-bit counter reflects unicast frames transmitted without
errors on port 1.
P2TxUniFrmCnt: This 16-bit counter reflects unicast frames transmitted without
errors on port 2.
P1TxBytCnt: This 32-bit counter reflects byte count of unicast, multicast and
broadcast frames transmitted without errors on port 1. Since this register may be
updated while the reads are under progress, this counter must be read twice and only
when two successive reads produce same result should the value be used.

P1TxSClFrmCnt: This 16-bit counter reflects frames transmitted after exactly one
collision in half duplex mode on port 1.
P2TxSClFrmCnt: This 16-bit counter reflects frames transmitted after exactly one
collision in half duplex mode on port 2.
P1TxMClFrmCnt: This 16-bit counter reflects frames transmitted after more than
one collision in half duplex mode on port 1.
P2TxMClFrmCnt: This 16-bit counter reflects frames transmitted after more than
one collision in half duplex mode on port 2.
P1TxXClFrmCnt: This 16-bit counter reflects frames dropped after excessive (16)
collisions in half duplex mode on port 1.
P2TxXClFrmCnt: This 16-bit counter reflects frames dropped after excessive (16)
collisions in half duplex mode on port 2.
P1TxErrFrmCnt: This 16-bit counter reflects frames truncated with error during
transmission on port 1.
