When allocating Rx related buffers, alloc_pages is called using an
order
number that is decreased until successful. A system under stress can
experience failures during this allocation process resulting in a
warning
being issued. This message can be of concern to end users even though
the
failure is not fatal. Since the failure is not fatal and can occur
multiple times, the driver should include the __GFP_NOWARN flag to
suppress the warning message from being issued.

Applied, thanks.
Hi David,

Can this be queued up for stable 4.0/4.1 (it isn't applicable before
3.19)?
