Title: Intel ethernet I219 has slow RX speed Status in HWE Next: New Status in linux package in Ubuntu: New Status in linux-oem package in Ubuntu: New Status in linux-oem-osp1 package in Ubuntu: New Status in linux source package in Bionic: New Status in linux-oem source package in Bionic: New Status in linux-oem-osp1 source package in Bionic: New Status in linux source package in Disco: New Status in linux-oem source package in Disco: Invalid Status in linux-oem-osp1 source package in Disco: Invalid Bug description: [Impact] RX speed on Intel ethernet I219 v6 is extremely slow due to multiple RX CRC errors. [Fix] Disable e1000e K1 feature to make I219 and PCH operate at higher speed to avoid the issue. [Test] Before applying the patch, the RX is slower than 150Kbps. After applying the fix the RX speed can achive gigabits. [Regression Potential] Low. This only applies to recent I219 generations. I've also test several other systems with e1000e and I don't see any regression.
