Hi, Our team has verified Ubuntu 18.04 + "proposed" solve the problem and as far as I am concerned, we could mark the tag as "verification-done- bionic":
</VMware Hi Zheng, Similar to update #44, I have verified that the bug has been fixed in Ubuntu 18.04 + "proposed" with the following steps : - Configure only with e1000e driver and reboot 3 times - Configure with both e1000e driver and vmxnet3 driver and reboot 3 times - Configure only with vmxnet3 driver and reboot 3 times - Reconfigure the driver from vmxnet3 to e1000e and reboot 3 times After each reboot, check output of "ifconfig" and everything goes well.

Specifically, the driver configures auto-clearing of the "OTHER" interrupt types, and the "OTHER" interrupt handler expects to see an uncleared interrupt source for the "OTHER" types; consequently, the link state change interrupts are not identified by the driver, and thus the virtual E1000e device doesn't function correctly inside VMware VMs. This patch Fixes: 4aea7a5c5e94 ("e1000e: Avoid receiver overrun interrupt bursts") == Fix == 745d0bd3af99 ("e1000e: Remove Other from EIAC") == Regression Potential == Low. Fixes an existing regression and limited to e1000e driver. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. == Original Bug Description == Hi Ubuntu folks, Linux kernel 4.15 has introduced a bug in e1000e msix interrupt drivers, which violates the e1000e specification. Specifically, the driver configures auto-clearing of the "OTHER" interrupt types, and the "OTHER" interrupt handler expects to see an uncleared interrupt source for the "OTHER" types; consequently, the link state change interrupts are not identified by the driver, and thus the virtual E1000e device doesn't function correctly inside VMware VMs. I have verified that Linux kernel 4.16.2 has fixed the issues and our on-perm QE has verified 4.16-RC functions correctly inside VMware VMs. Could you please crossport the fix from linux-4.16 into Ubuntu 18.04 that would be frozen in 2 days?
