[ipxe-devel] I219-LM download speed issue

[Malte zu Klampen]

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. PCI_ROM ( 0x8086, 0x15a2, "i218lm-3", "I218-LM", INTEL_NO_PHY_RST ), + PCI_ROM ( 0x8086, 0x15b7, "i219lm-2", "I219-LM (2)", INTEL_NO_PHY_RST ),
