Moin,
see http://forum.ipxe.org/showthread.php?tid=7571 for reference. This
issue evidently also affects newer Intel NICs. Attached and below is a
fix for I219-LM that I could personally test. A 300MB squashfs transfers
in ~3 seconds with the patch applied, or ~5 minutes without it.
I hypothesise that this issue affects all NICs of the same line, but I
don't have the hardware to confirm.
