This is due to check sum handling issue in the vmxnet3 driver. Fix is on
the kernel tree.
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-
stable.git/commit/drivers/net/vmxnet3?
id=f0d437809d23999cb25207cfbe80c61e5703fdc1
I have tested the fix and confirmed to resolve the performance issue with
LRO.
Thanks
Ram
