Subject: [net-next-2.6 PATCH 2/5] ixgbe: Make descriptor ring allocations
NUMA-aware
From: PJ Waskiewicz <peter.p.waskiewicz.jr@...el.com>
This patch allocates the ring structures themselves on each
NUMA node along with the buffer_info structures. This way we
don't allocate the entire ring memory on a single node in one
big block, thus reducing NUMA node memory crosstalk.
