Users of librte_vhost currently implement the vring call operation
themselves. Each caller performs the operation slightly differently.
This patch introduces a new librte_vhost API called
rte_vhost_vring_call() that performs the operation so that vhost-user
applications don't have to duplicate it

So far, about hot plug in dpdk, we already have hot plug add/remove

This driver uses ethtool to get link status. The ethtool API has new

same algorithm that the ethtool command does; check the new API first
and if that fails, try the old one.
Also, use common code for getting link state up/down a

The current driver requires v16. It will not work or build with
the older version (as in Debian stable). Note: libmlx5 is rolled
into rdma-core in current versions.
Mlx4 probably requires similar documentation update.

This series is to convert mlx4 and mlx5 PMDs to the new offloads API [1].
On v2:
- New design to hold PMD specific args and combine
them with offloads requested.
- Fix missing IPV4 checksum flag on vector function selection.
- Verify Txq flags ignore bit before checking for valid offloads
Change the function prototype to return the function pointer of the
selected Tx/Rx burst function instead of assigning it directly to the
device context.
Such change will enable to use those select functions to query the burst
function that will be selected according to the device configuration.
Ethdev Tx offloads API has changed since:
