As stated in README, some e1000 cards don't work well with low end switches (can't establish link). There's a workaround, I changed the ebuild to apply it without the need to change the ebuild itself and added some docs on how to do it. Reproducible: Always Steps to Reproduce:
Created attachment 26610 [details, diff] e1000-5.2.30.1.patch
Created attachment 26611 [details] README.Gentoo Detailed instructions on how to apply the workaround.
