Technology Ability Field is an 8-bit field containing
information indicating supported technologies specific
to the selector field value.
The Selector Field is a 5-bit field identifying the type of
message to be sent via Auto-Negotiation. This field is
read only in the 82551IT and contains a value of
00001b, IEEE Standard 802.3.
Constant 0 = Transmitting primary capability data
This bit is reserved and should be set to 0b.
1 = Indicate link partner’s remote fault
