"net_virtio" is correct for the virtio driver. However, you probably need
to do like is done for the other network drivers linked into the autotest,
and make it conditional on the support being present, since not every build
enables the virtio driver. For example, as is currently in the meson.build
for the autotests:
# The following linkages of drivers are required because
# they are used via a driver-specific API.
if dpdk_conf.has('RTE_NET_BOND')
test_deps += 'net_bond'
test_sources += ['test_link_bonding.c', 'test_link_bonding_rssconf.c']
...
endif
