Reporting the Link Partner Capabilities
TABLE 4-11 describes the read-only link partner capabilities.
If the link partner is not capable of autonegotiation (when lp_cap_autoneg is 0),
the remaining information described in
TABLE 4-11 is not relevant and the parameter
value = 0.
If the link partner is capable of autonegotiation (when lp_cap_autoneg is 1), then
the speed and mode information is displayed when you use autonegotiation and the
link partner capabilities.
