10Base-T

Selector

1 = 100Base-TX is supported by link partner

0 = 100Base-TX not supported by link partner

This bit will also be set after the link in 100Base is

established by parallel detection.

1 = 10Base-T full duplex is supported by link partner

0 = 10Base-T full duplex not supported by link partner

1 = 10Base-T is supported by link partner

0 = 10Base-T not supported by link partner

This bit will also be set after the link in 10Base is

established by parallel detection.

Link Partner’s binary encoded node selector

Currently only CSMA/CD <00001> is specified
