From: Mats Liljegren Date: Fri, 24 Jan 2014 13:24:14 +0000 (+0100) Subject: ethdev: introduce if_index in device info X-Git-Tag: spdx-start~10936 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a12f21157afad0dc4c3d3618d5a664a54e9b6607;p=dpdk.git ethdev: introduce if_index in device info This field is intended for pcap to describe the name of the interface as known to Linux. It is an interface index, but can be translated into an interface name using if_indextoname() function. When using pcap, interrupt affinity becomes important, and this field gives the application a chance to ensure that interrupt affinity is set to the lcore handling the device.
