• {link speed} – expected link speed
• AN {link speeds} – advertised supported auto-negotiation link speeds.
The expected link speeds based on the local and link partner settings are shown in Table 2 8 .
To enable link speed auto-negotiation, the following options can be enabled in system BIOS HII menu or in CCM:
System BIOS->Device Settings->NetXtreme-E NIC->Device Level Configuration
Operational Link Speed
This option configures the link speed used by the preboot (MBA and UEFI) drivers (Linux, ESX), OS driver, and firmware. This setting is overridden by
the driver setting in the OS present state. The Windows driver (bnxtnd_.sys) uses linkspeed settings in the driver .inf file.
