In the existing implementation, the blockcipher test cases are being run
and reported as one test case per type, even though multiple test cases
are hidden in each. For example, "test_AES_chain_all" runs 46 test cases.
Each blockcipher type should have a testsuite instead.
The blockcipher testsuite is dynamically built, depending on the
blockcipher type chosen. The testcase struct is modified to allow
running a testcase with data, which is used for data required when
running each blockcipher testcase.
The blockcipher testsuites are added dynamically to parent testsuites
as sub-testsuites where needed.

The vhost library currently configures Tx offloading (PKT_TX_*) on any
packet received from a guest virtio device which asks for some offloading.
This is problematic, as Tx offloading is something that the application
must ask for: the application needs to configure devices
to support every used offloads (ip, tcp checksumming, tso..), and the
various l2/l3/l4 lengths must be set following any processing that
happened in the application itself.
On the other hand, the received packets are not marked wrt current
packet l3/l4 checksumming info.
Copy virtio rx processing to fix those offload flags with some
differences:
- accept VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP,
- ignore anything but the VIRTIO_NET_HDR_F_NEEDS_CSUM flag (to comply with
the virtio spec),
Some applications might rely on the current behavior, so it is left
untouched by default.
A new RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS flag is added to enable the
new behavior.
The vhost example has been updated for the new behavior: TSO is applied to
any packet marked LRO.

The driver should notify the guest for each traffic burst detected by CQ
polling.
The CQ polling trigger is defined by `event_mode` device argument,
either by busy polling on all the CQs or by blocked call to HW
completion event using DevX channel.
Also, the polling event modes can move to blocked call when the
traffic rate is low.
The current blocked call uses the EAL interrupt API suffering a lot
of overhead in the API management and serve all the drivers and
libraries using only single thread.
Use blocking FD of the DevX channel in order to do blocked call
