c869993e79c1eafbec61a56bf6cea848fe754c71xy# There are two methods to configure the link:
c869993e79c1eafbec61a56bf6cea848fe754c71xy# autonegotiation or forced link
6d1cdc09693601c358cdcd1bbd6a462920ac89adGuoqing Zhu# The parameter "adv_autoneg_cap" is used to enable autonegotiation or disable
c869993e79c1eafbec61a56bf6cea848fe754c71xy# it (forced link mode).
6d1cdc09693601c358cdcd1bbd6a462920ac89adGuoqing Zhu# If autonegotiation is enabled (the default mode), all the "adv_*_cap"
c869993e79c1eafbec61a56bf6cea848fe754c71xy# parameters control which capabilities are advertised to the partner. The
c869993e79c1eafbec61a56bf6cea848fe754c71xy# default is to advertise all the capabilities that the hardware supports.
c869993e79c1eafbec61a56bf6cea848fe754c71xy# The advertised capabilities can also be restricted to a subset. It is not
c869993e79c1eafbec61a56bf6cea848fe754c71xy# possible to advertise a capability that the hardware does not support.
c869993e79c1eafbec61a56bf6cea848fe754c71xy# The autonegotiation process will then automatically select the fastest speed/
c869993e79c1eafbec61a56bf6cea848fe754c71xy# duplex mode supported by both partners.
c869993e79c1eafbec61a56bf6cea848fe754c71xy# If autonegotiation is disabled (forced link mode), the link speed/duplex is
c869993e79c1eafbec61a56bf6cea848fe754c71xy# determined by the first link capability that is enabled, in highest-to-lowest
6d1cdc09693601c358cdcd1bbd6a462920ac89adGuoqing Zhu# For example, if adv_1000fdx_cap is enabled, all other values will be ignored;
