(In reply to comment #0) > how to resolve issue? Like, set your link speed properly with ethtool/mii-tool or whatever? This is not a support forum and you didn't post any information to debug the issue, let alone an information that would suggest that it's a Gentoo-specific bug.
I am not sure if this is gentoo spefic, since I am unable to resolve the issue, but there is ethtool output Settings for eth0: Supported ports: [ MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: g Wake-on: d Current message level: 0x000000ff (255) Link detected: yes
