A new attempt at adding support for Intel 82576 Gigabit Ethernet adapter
with SR-IOV support.
Start qemu with the following parameters.
qemu-system-x86_64 -enable-kvm -M q35 \
...
-device pcie-root-port,slot=3,id=pcie_port.3 \
-netdev tap,id=net3,script=no,downscript=/tmp/rmtap,ifname=xcbr3_t2,queues=1 \
-device igb,bus=pcie_port.3,netdev=net3,mac=00:00:00:01:03:02
Load IGB/IGBVF modules if needed.
modprobe igb
modprobe igbvf
Create VFs via /sys
ls /sys/bus/pci/devices/0000:01:00.0/
echo 2 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs
Changes since v1:
- Added qtest for igb
Sriram Yagnaraman (6):
pcie: add helper function to get number of VFs
hw/net/net_tx_pkt: helper function to get l2 hdr
hw/net/igb: register definitions
hw/net/igb: emulated intel IGB (82576EB) network device
hw/net/igb: build support for igb/igbvf devices
tests/qtest/igb-test: introduce qtest for igb
