When receiving coalesced packets in virtio, the original size of the
segments is provided. This is a useful information because it allows to
resegment with the same size.
Add a RX new flag in mbuf, that can be set when packets are coalesced by
a hardware or virtual driver when the m->tso_segsz

Following discussions in [1] and [2], introduce a new bit to
describe the Rx checksum status in mbuf.
Before this patch, only one flag was available:
PKT_RX_L4_CKSUM_BAD: L4 cksum of RX pkt. is not OK.
And same for L3:
PKT_RX_IP_CKSUM_BAD: IP cksum of RX pkt. is not OK.

This function will be used by the virtio pmd in next commits to calculate
the checksum in software in case the protocol is not recognized.

Add the ability to reset the virtio device in the configure callback
if the features flag changed since previous reset. This will be possible

Move the configuration of control queue in the configure callback.
This is needed by next commit, which introduces the reinitialization
of the device in the configure callback to change the feature flags.
Therefore, the control queue will have to be restarted at the same
place.
As
Move all code related to device initialization in a new function
virtio_init_device().
This commit brings no functional change, it prepares the next commits
that will add the offload support. For that, it will be needed to
reinitialize the device from ethdev->configure(), using this new
function.
This patchset, targetted for 16.11, introduces the support of rx and tx
offload in virtio pmd. To achieve this, some new mbuf flags must be
introduced, as discussed in [1].
It applies on top of:
- 16.07-rc3
- software packet type [2]
- testpmd enhancements [3]
- virtio packet corruption fix [4]

We find significant perfermance drop introduced by below commit,
when vhost example is started with --mergeable 0 and inside vm,
kernel virtio-net driver is used to do ip based forwarding.
The commit, 859b480d5afd ("vhost: add guest offload setting"), adds
support for VIRTIO_NET_F_GUEST_TSO4 and
