vdpa/mlx5: fix notification timing

The issue is relevant only for the timer event modes: 0 and 1.

When the HW finishes to consume a burst of the guest Rx descriptors,
it creates a CQE in the CQ.
When traffic stops, the mlx5 driver arms the CQ to get a notification
when a specific CQE index is created - the index to be armed is the
next CQE index which should be polled by the driver.

The mlx5 driver configured the kernel driver to send notification to
the guest callfd in the same time of the armed CQE event.
It means that the guest was notified only for each first CQE in a
poll cycle, so if the driver polled CQEs of all the virtio queue
available descriptors, the guest was not notified again for the rest
because there was no any new CQE to trigger the guest notification.

Hence, the Rx queues might be stuck when the guest didn't work with
poll mode.

Remove prior kernel notification, and do manual notification after CQ
polling.

net/mlx4: fix premature disabling of interrupt

RXQ interrupts under Linux are based on the epoll mechanism. An
expected order of operations is as follows:
1. Call rte_eth_dev_rx_intr_enable(), to arm the CQ for receiving events
on data input.
2. Block on rte_epoll_wait() with an array of file descriptors

input event on the corresponding CQ fd.
3. Call rte_eth_dev_rx_intr_disable() after the event was received and
continue in polling mode. The mlx4 implementation of
rte_eth_dev_rx_intr_disable() is to get the CQ event and ack it.

In practice applications may wake up from rte_epoll_wait() due to
timeout with no event to ack but still call
rte_eth_dev_rx_intr_disable() unconditionally.  In such cases the call

net/mlx5: fix dynamic inline hint handling

The ConnectX NICs can transfer data from the host memory with two
approaches: provide the pointer to the data buffer, or do data inline
- copy the data to the transmit descriptor (WQE) entirely or only the
part of data. In some configurations the NIC hardware requires the
minimal data to be inline in the descriptor to operate correctly. And
there is the special dynamic flag to hint PMD not to inline the data
(for example, if buffer is located on some other device - storage or
GPU) on per packet basis.

If there was a packet with length shorter than the minimal inline data
length requested by the NIC hardware and the no-inline hint was set
the PMD tried to inline the packet with minimal required length

net/mlx5: fix premature disabling of interrupt

RXQ interrupts under Linux are based on the epoll mechanism. An expected
order of operations is as follows:
1. Call rte_eth_dev_rx_intr_enable(), to arm the CQ for receiving events
   on data input.
2. Block on rte_epoll_wait() with an array of file descriptors
   representing the CQ events. Upon data arrival the kernel will signal
   an input event on the corresponding CQ fd.
3. Call rte_eth_dev_rx_intr_disable() after the event was received and
   continue in polling mode. The mlx5 implementation of
   rte_eth_dev_rx_intr_disable() is to get the CQ event and ack it.

In practice applications may wake up from rte_epoll_wait() due to
timeout with no event to ack but still call
rte_eth_dev_rx_intr_disable() unconditionally.  In such cases the call
should return EAGAIN (since the file descriptors are non-blocked), as

Unlike net device this application loads data from a file.

This commit introduces the new RegEx test app.

The basic app flow:
1. Configure the RegEx device to use one queue, and set the rule
   database, using precompiled file.
2. Allocate mbufs based on the requested number of jobs, each job will
i  get one mbuf.
3. Enqueue as much as possible jobs.
4. Dequeue jobs.
5. if the number of dequeue jobs < requested number of jobs job to step

regex/mlx5: fix overrun on enqueueing

When enqueueing a buffer the PMD check if there is room
in its send queue (SQ).
The current implementation did not take into account that
queue indices are wrapping around, which may result in
