[PATCH 2/2] ixgbe: Use core to device locality interface

2015-12-23 Thread Daniel J Blueman
Rather than assuming cores starting from 0 are local to the ethernet device, use the introduced interface to find near cores. Not only does this improve performance due to spreading interrupts via near NUMA nodes, it prevents assigning cores on distant NUMA nodes, which aren't reachable by device
