Now that we require 13c6be96618c ("net: stream: add unix socket") in qemu to run the tests, we can also assume that commit df8d07081718 ("virtio-net: fix bottom-half packet TX on asynchronous completion") is present, as it was merged before that one. This fixes the issue we attempted to work around in passt TCP and UDP performance tests: finally drop that stuff. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
