Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:
- First, because it uses perfect hashing, it does not store
the key itself and hence lookup performance is not dependent
on the key size.
- Second, the target/value can be any arbitrary value hence
the system designer and/or operator can better optimize service rates
and inter-cluster network traffic locating.
- Third, since the storage requirement is much smaller than a hash-based
flow table (i.e. better fit for CPU cache), EFD can scale to
millions of flow keys.
Finally, with current optimized library implementation performance
is fully scalable with number of CPU cores.

This commit introduces 8-bit, 16-bit, 32bit, 64bit I/O device
memory read/write operations along with the relaxed versions.
The weakly-ordered machine like ARM needs additional I/O barrier for
device memory read/write access over PCI bus.
By introducing the eal abstraction for I/O device memory read/write access,
The drivers can access I/O device memory in architecture agnostic manner.
The relaxed version does not have additional I/O memory barrier, useful in
accessing the device registers of integrated controllers which
implicitly strongly ordered with respect to memory access.
