This is an update version of last version to fix the handling of polling errors in vhost/vhost_net. Currently, vhost and vhost_net ignore polling errors which can lead kernel crashing when it tries to remove itself from waitqueue after the polling failure. Fix this by checking the poll->wqh before the removing and report an error when meet polling errors. Changes from v2: - check poll->wqh

This patch series resurrects the earlier multiple TX/RX queues functionality for virtio_net, and addresses the issues pointed out. It also includes an API to share irq's, f.e. amongst the TX vqs. I plan to run TCP/UDP STREAM and RR tests for local->host and local->remote, and send the results in the next couple of days. patch #1: Introduce VIRTIO_NET_F_MULTIQUEUE patch #2: Move
