Indicates the advertised ability of the local hardware, but only
becomes active on ports that have auto-negotiation enabled.
The value is a sum. This sum initially takes the value zero. Then, for
each technology, T, that the port is advertising, 2 raised to (T - 1)
is added to the sum. For example, a port that advertises 1000BASE-TFD
(T = 18) and 1000BASE-T (T = 17) would return a value of 196608
((2 ^ (18 - 1)) + (2 ^ (17 - 1))).
Values for T are limited to technologies supported by the hardware as
specified by ctAutoNegLocalTechnologyAbility. For ports supporting
Auto-Negotiation, values should be calculated as follows:

A successful set operation will result in immediate link re-negotiation
if Auto-Negotiation is enabled on this port, as specified by
ctAutoNegAdminStatus. A set of this object to a value containing bits
that are not supported by the hardware will be successful, but, the port
will only advertise values which are the logical AND of the set value and
ctAutoNegLocalTechnologyAbility.
Note: this re-negotiation will in every case cause temporary link loss
during the link re-negotiation. If set to a value that is incompatible
with ctAutoNegLocalTechnologyAbility, link negotiation will not
be successful and will cause permanent link loss.
