Hi Greg,

Found few e100e upstream fixes from Benjamin Poirier in lede source tree, https://git.lede-project.org/?p=source.git, and these fixes seem reasonable enough for 4.14.y too.

Also submitting an e1000e buffer overrun fix by Sasha Neftin.

Cherry-picked and build tested for linux v4.14.2 for ARCH=arm/arm64.

Regards, Amit Pundir

Hello everybody,

looks like one of these breaks connectivity on my Thinkpad X250. Just downgraded to linux 4.14.2 to verify.

Can you try the -rc release I just did? It has a fix for this series in it.

It connects with the notebook's built in ethernet port (did not check with 4.14.3) but still fails to see a link when placed in docking station.

Do you have the same issues with 4.15-rc2?

thanks,

greg k-h
