Subject: [PATCH net-next 0/2] bnx2x: page allocation failure
Date: Fri, 16 Sep 2016 17:30:32 -0400 [thread overview]
Message-ID: <cover.1474060371.git.jbaron@akamai.com> (raw)
Hi,
While configuring ~500 multicast addrs, we ran into high order
page allocation failures. They don't need to be high order, and
thus I'm proposing to split them into at most PAGE_SIZE allocations.
Below is a sample failure.
Thanks,
-Jason
