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? Here are the change history:
https://lkml.org/lkml/2018/3/25/248
Benjamin Poirier (7):
e1000e: Remove Other from EIAC
Partial revert "e1000e: Avoid receiver overrun interrupt bursts"
e1000e: Fix queue interrupt re-raising in Other interrupt
e1000e: Avoid missed interrupts following ICR read
e1000e: Fix check_for_link return value with autoneg off
Revert "e1000e: Separate signaling for link check/link up"
e1000e: Fix link check race condition
Thanks,

== SRU Justification ==
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.
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.
