Subject: [dpdk-dev] [PATCH v5 7/7] net/ice: get the VF hardware index in DCF
Date: Thu, 26 Mar 2020 15:15:25 +0800
Message-ID: <20200326071525.4088-8-haiyue.wang@intel.com> (raw)
In-Reply-To: <20200326071525.4088-1-haiyue.wang@intel.com>

The DCF (Device Config Function) needs the hardware index of the VFs to
control the flow setting. And also if the VF resets, the index may be
changed, so it should handle this in VF reset event.
