usxgmii_link_tim
er
Auto-Negotiation link timer. Sets the link timer value in
bit [19:14] from 0 to 2 ms in approximately 0.05-ms
steps. You must program the link timer to ensure that it
matches the link timer value of the external NBASE-T
PHY IP Core.
The reset value sets the link timer to approximately 1.6
ms.
Bits [13:0] are reserved and always set to 0.
