10BASE-T: If the MR1.11 bit is ‘1’, this bit will be set to ‘1’
upon reset and will be writeable. Otherwise, this bit cannot be
set to ‘1’ by the management.

01h
Selector Field: Hard coded with the value of ‘00001’ for IEEE
802.3.
Note: Technology Ability Field: MR4.12:5 are the Technology Ability Field bits (A7:0). The default value
of this field is dependent upon the MR1.15:11 register bits. This field can be overwritten by management
to auto-negotiate to an alternate common technology. Writing to this register has no effect until
auto-negotiation is re-initiated.

Technology Ability Field: This field contains the technology
ability of the link partner. The bit definition is the same as
MR4.12:5.
5.4:0

00h
Selector Field: This field contains the type of message sent by
the link partner. For an IEEE 802.3 compliant link partner, this
field should be ‘00001’.
