LINK_EN

Setting this bit enables linking. If linking is disabled, the PHY enters the standby state and does not

attempt to bring up links. The standby state can be used to run diagnostics, including cable diagnostics.

0x1

R/W

1: enable linking.

0: disable linking.

[12:10]

NUM_SPEED_RETRY

If downspeed is enabled, this register bit specifies the number of retries the PHY must attempt to bring up

a link at the advertised speed before advertising a lower speed. By default, the PHY attempts to bring up a

link 5 times (4 retries) before downspeeding.
