In this patch, we removed the necessity of the version files and
you don't need to update these files for each release, you can just
remove them.

The reason for not building is updated
to be consistent with other drivers.
The libibverbs was not detected through pkg-config.
The method dependency() needs to be used first.
The support in rdma-core and Linux is not released yet,
so the documentation is updated.

MANA allocates device queues through the IB layer when starting Rx queues.
When device is stopped all the queues are unmapped and freed.

The hardware layer of MANA understands the device queue and doorbell
formats. Those functions are implemented for use by packet RX/TX code.

MANA hardware has iommu built-in, that provides hardware safe access to
user memory through memory registration. Since memory registration is an
expensive operation, this patch implements a two level memory registration
cache mechanisum for each queue and for each port.

for queue configuration pre starting.

Currently this PMD supports RSS configuration when the device is stopped.
Configuring RSS in running state will be supported in the future.

MANA supports PCI hot plug events. Add this interrupt to DPDK core so its
parent PMD can detect device removal during Azure servicing or live
migration.

MANA defines its memory allocation functions to override IB layer default
functions to allocate device queues. This patch adds the code for device
configuration and stop.

MANA is a PCI device. It uses IB verbs to access hardware through the
kernel RDMA layer. This patch introduces build environment and basic
device probe functions.
