Ensure jumbo mode is enabled and that the mbuf data room size can
accommodate jumbo size. If the mbuf data room size can't accommodate
jumbo size, chain mbufs to jumbo size.

Add a non-coalesce path. Skip coalescing for Jumbo Frames, and send the
packet through non-coalesced path if there are enough credits. Also,
free these non-coalesced packets while reclaiming credits.

Update sge initialization with respect to free-list manager configuration
and ingress arbiter. Also update refill logic to refill mbufs only after
a certain threshold for rx. Optimize tx packet prefetch.
Approx. 3 MPPS improvement seen in forwarding performance after the
optimization.

The extended unified packet type is now part of the standard ABI.
As mbuf struct is changed, the mbuf library version is incremented.

Fix "MACRO redefined" and "function redefined" compilation errors in FreeBSD
by adding CXGBE prefix to them. Also remove reference to a linux header
linux/if_ether.h and use DPDK macros directly. Finally, enable CXGBE PMD
for FreeBSD.

To unify packet types among all PMDs, bit masks of packet type for
'ol_flags' are replaced by unified packet type.
To avoid breaking ABI compatibility, all the changes would be enabled
by RTE_NEXT_ABI.

CXGBE PMD rx allocates a new mbuf everytime, which could lead to performance
hit. Instead, do bulk allocation of mbufs and re-use them.
Also, simplify the overall rx-handler, and update its logic to fix rx perf.

When compiling the cxgbe driver with icc, multiple errors about using
enums as integers appear across a number of files, including in the base
code and in the DPDK-specific driver code.
.../drivers/net/cxgbe/cxgbe_main.c(386): error #188: enumerated type mixed
with another type
t4_get_port_type_description(pi->port_type));
^
For the errors in the base driver code we use the CFLAGS_BASE_DRIVER
approach used by other drivers to disable warnings.
For errors in the DPDK-specific code, typecasts are used to fix the
errors in the code itself.

GCC_VERSION is empty in case of clang:
/bin/sh: line 0: test: -ge: unary operator expected
It cannot be quoted because an integer is expected.
So the fix is to check empty value in a separate test.

Adds cxgbe poll mode driver for DPDK under drivers/net/cxgbe directory.
This patch:
1. Adds the Makefile to compile cxgbe pmd.
2. Registers and initializes the cxgbe pmd driver.
Enable cxgbe PMD for compilation and linking with changes to:
1. config/common_linuxapp to add macros for cxgbe pmd.
2. drivers/net/Makefile to add cxgbe pmd to the compile list.
3. mk/rte.app.mk to add cxgbe pmd to link.
Update MAINTAINERS file to claim responsibility for the cxgbe PMD.
