Subject: [dpdk-dev] [PATCH v2 0/4] introduce new iavf driver on vfio-user client
Date: Thu,  7 Jan 2021 15:45:29 +0800
Message-ID: <20210107074533.15465-1-jingjing.wu@intel.com> (raw)
In-Reply-To: <20201219143816.64174-1-jingjing.wu@intel.com>

This series introduces a new net virtual device called iavf_client which
is based on vfio-user client interface. Through vfio-user client interface,
PCI liked device could be used similar as Intel® Ethernet Adaptive Virtual
Function specification.
The code to enable iavf_client mainly contains two parts:
 - Emulated pci interfaces for vfio-user client which is located
   in common/iavf/vfio_user/.
 - A new net driver base on vdev abstraction, i.e. iavf_client_ethdev.c

This driver can be used to test the device emulation framework

It can be launched together with patch series for the testing:
  [0/9] Introduce vfio-user library:
  http://patchwork.dpdk.org/cover/85389/
  [0/8] Introduce emudev library and iavf emudev driver
  http://patchwork.dpdk.org/cover/85488/
