Add an option boolean flag 'use_mask_notifier' to disable the use
of guest_notifier_mask in virtio pci.

}
else null handler is set in guest_notifier.
And from my understanding, virtio-pci in kvm mode uses irqfd, so when are
we entering the virtio_queue_guest_notifier_read?
did you also change the qemu configuration?
thanks

Hi,
I recently did some stress tests of a vhost-user interface using an UDP
traffic generator. Traffic generator was connected to 2 physical ports
that are in turn connected to 2 virtio ports through a linux bridge, VM
(running linux) doing routing
/unmasking interrupts

Patches 2 and 3 of the serie propose an implementation of this second option.

char: fix vhost-user socket full
virtio-pci: add an option to bypass guest_notifier_mask
vhost-net: force
is called through qemu_chr_fe_write, it will be
user responsability to resend message as is or to free write_msgfds
using set_msgfds(0)

Since guest_mask_notifier can not be used in vhost-user
mode due to buffering implied by unix control socket,
force VIRTIO_PCI_FLAG_USE_NOTIFIERMASK on virtio pci
of vhost-user interfaces, and send correct callfd
to the guest at vhost start.
