Statistics Registers
Single Collision Count - SCC PHY Address 01, Page 778, Registers 16 - 17
This register counts the number of times that a successfully transmitted packet
encountered a single collision. This register only increments if transmits are enabled
and the 82577 is in half-duplex mode.

The TTV field is inserted into a transmitted
frame (either XOFF frames or any pause frame
value in any software transmitted packets). It
counts in units of slot time. If software needs
to send an XON frame, it must set TTV to
0x0000 prior to initiating the pause frame.
Reserved, write as read.
Enable generation of early preamble based on
RX_DV in the receive path.
Enable generation of early preamble based on
CRS in the receive path.
Reserved, write as read.
Align the packet’s start of frame delimiter to a
byte boundary in the receive path.
Reserved, write as read.
Reserved
When set, disables filtering of Rx packets for
the SMBus.
In wake up mode, this configuration is
ignored and the filters are enabled.
