From: Wei Hu (Xavier) Date: Thu, 26 Sep 2019 14:02:01 +0000 (+0800) Subject: net/hns3: support VF X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a5475d61fa34b8e8d17dbb8d5d47a811bbd390a9;p=dpdk.git net/hns3: support VF This patch adds support for hns3 VF PMD driver. In current version, we only support VF device is bound to vfio_pci or igb_uio and then driven by DPDK driver when PF is driven by kernel mode hns3 ethdev driver, VF is not supported when PF is driven by DPDK driver.
