LinkCap and LinkCtl2 do not reflect the link status. If lspci command lists the NIC card entry, it means the link is up. If lspci only lists one entry which is the PCI bridge, it means the link is down. Up0TrueDown Lawrence Wong6 年多前in reply toBin Liu ...

b) Electrical Idle means the differential voltage applied to the link is ~0V (no signaling). If there is ~0V differential, then the RX cannot recover a clock and bit/symbol lock is lost. 简而言之,电气空闲属于物理上的,D+与D-的电压差值趋近于0v,RX无法完成bit lock。
