When vhost-user connects qemu successfully, dpdk will call
the vhost_user_add_connection to add unix socket fd to poll.
And fdset_add only set the socket fd to a fdentry while poll
may sleep now. In a general case, this is no problem. But if
we use hot update for vhost-user, most downtime of VMs network
is 750+ms. This patch adds pipe event, so after connections are
ok, dpdk rebuild the poll immediately. With this patch, the
most downtime is 20~30ms.

When first call the 'rte_vhost_driver_start', the
fdset_event_dispatch thread should be created successfully.
Because the vhost uses it to poll socket events for vhost
server or clients. Without it, for example, vhost will not
get the connection event.
This patch returns err code directly when created not successful.

When creating vdev dynamically, vhost pmd driver starts directly without
checking TX/RX queues are ready or not, and thus causes segmentation fault
when vhost library accesses queues. This patch adds a flag to check whether
queues are setup or not, and adds queues setup into dev_start function to
allow user to start them after setting up.

This patch aims at fixing a migration performance regression
faced since atomic operation is used to log pages as dirty when
doing live migration.
Instead of setting a single bit by doing an atomic read-modify-write
operation to log a page as dirty, this patch write 0xFF to the
corresponding byte, and so logs 8 page as dirty.
The advantage is that it avoids concurrent atomic operations by
multiple PMD threads, the drawback is that some clean pages are
marked as dirty and so are transferred twice.

rte_eth_dev_pci_release() function wrongly releases an ethdev port and
then releases internal fields of this port.
This behavior is problematic, because after the release, the port may
be reallocated again by another thread or just be invalid for any
usage.
Move the release operation to the end of the function.

In some environments it is desirable to have the NIC perform RSS
normally on the packet regardless of the number of queues configured.
The RSS hash result that is stored in the mbuf can then be used by
the application to make decisions about how to distribute workloads
to threads, secondary processes, or even virtual machines if the
application is a virtual switch. This change to the mlx5 driver
aligns with how other drivers in the Intel family work.
