From cebf7f17159a80e10243ff4f42214646fb76a6a7 Mon Sep 17 00:00:00 2001 From: Xueming Li Date: Thu, 11 Mar 2021 13:13:26 +0000 Subject: [PATCH] ethdev: support new VF representor syntax Current VF representor syntax: representor=2 - single representor representor=[0-3] - single range To prepare for more representor types, this patch adds compatible VF representor devargs syntax: vf#: representor=vf2 - single representor representor=vf[1,3,5] - single list representor=vf[0-3] - single range representor=vf[0,1,4-7] - list with singles and range For backwards compatibility, representor "#" is interpreted as "vf#".
