f324162e8e regex/mlx5: support combined rule file
The rof file holds programming instructions for
a given HW version.
In order to support future generation of HW it
was decided that the rof file will hold number
of rule configurations, and the driver will use
the one that matches the HW version.

In current code we force sync after each write block.
This has impact on performance.

The solution is to move the sync to the end of the
entire programming sequence.

68fbbb8369 eal: avoid invalid power intrinsics API usage
Currently, the API documentation mandates that if the user wants to use
the power management intrinsics, they need to call the
`rte_cpu_get_intrinsics_support` API and check support for specific
intrinsics.

However, if the user does not do that, it is possible to get illegal
instruction error because we're using raw instruction opcodes, which may
or may not be supported at runtime.

Now that we have everything in a C file, we can check for support at
startup and prevent the user from possibly encountering illegal
instruction errors.

We also add return values to the API's as well, because why not.

VF device. The VF device driver communicates directly with the PCI device
via the PF from the host hypervisor. This is faster than exchanging data
with netvsp via vmbus, i.e. syntheic path.

In Azure and Hyper-v environments, VF device can be hot added or hot
removed at anytime while guest VM is running. This patch improves netvsc
to support VF device hot add/remove.

1. netvsc monitors all system hot add activities over the PCI bus. When it
detects a VF device is added to the system and is managed under this
netvsc device, it asks EAL to probe and start this VF device, then it
attaches and switches data path to the VF device.

2. After a VF device is attached to netvsc, netvsc monitors this device on
hot remove. When this VF device is hot removed, netvsc switches data path
to synthetic, stops this VF device and removes it from EAL.

3. If any failure happens during a VF device hot remove or add, the netvsc
falls back to synthetic path for all data traffic.

1fef6ced07 eal/linux: allow multiple starts of event monitor
In some cases, a device or infrastructure may want to enable hotplug
but application may also try and start hotplug as well. Therefore
change the monitor_started from a boolean into a reference count.

acdabc450e test: fix terminal settings on exit
When running one test (via DPDK_TEST) the test program
would leave the terminal in raw mode.  This was because
it was setting up cmdline to do interactive input.

The fix is to use cmdline_new() for the interactive case.

This also fixes a memory leak because the test
runner was never calling cmdline_free().
