== SRU Justification ==
The bug reporter was seeing an OOM on multiple servers after upgrading from 
previous 4.10 series HWE kernels to the new 4.13 HWE series. With the new 
kernel, free memory is continously decreasing at a high rate and the servers 
start swapping and finally OOMing services within days. With the 4.10 kernel, 
decrease of free memory is slower and stabilizes after a while.

It was found that upstream commits 2b9478ffc550 and 62b4c6694dfd resolve
this issue.

== Fixes ==
2b9478ffc550("i40e: Fix memory leak related filter programming status")
62b4c6694dfd("i40e: Add programming descriptors to cleaned_count")

== Regression Potential ==
Low.  Limited to i40e and fix existing regression.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
