248f9319f7 examples/netmap_compat: fix build on Suse 11
examples/netmap_compat/bridge/../lib/compat_netmap.c:880:41:
 error: ‘POLLRDNORM’ undeclared (first use in this function)

The root casue is POLLRDNORM is more-or-less nonstandard, and it
depends on macro "__USE_XOPEN".

In suse11 sp3, POLLRDNORM will not be defined because "__USE_XOPEN"
issue.

This patch add check if it is not defined, define it.

824cb29c0e apps: fix default mbuf size
Latest mbuf changes (priv_size addition and related fixes)
exposed small problem with testpmd and few other sample apps:
when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'
max packet length (max_rx_pkt_len == ETHER_MAX_LEN).
To overcome that problem and unify the code, new macro was created
to represent recommended minimal buffer length for mbuf.
When appropriate, samples are updated to use that macro.

Fixes: dfb03bbe2b ("app/testpmd: use standard functions to initialize
mbufs and mbuf pool")

ea0c20ea95 apps: use helper to create mbuf pools
When it's possible, use the new helper to create the mbuf pools.
Most of the patch is trivial, except for the following files that
have some specifics (indirect mbufs):
- ip_fragmentation
- ip_pipeline
- ipv4_multicast
- vhost

d50f463fbe examples/netmap_compat: fix overflow in ioctl operation
Compiling the netmap example with clang-3.5 triggered the following
warning:

68fa37e021 examples: do not probe pci twice
Since commit a155d43011 ("support link bonding device initialization"),
rte_eal_pci_probe() is called in rte_eal_init().
So it doesn't have to be called by application anymore.
It has been fixed for testpmd in commit 2950a76931,
and this patch remove it from other applications.

519f32279e config: rename "default" configurations as "native"
The "default" part in configuration filenames is misleading.
Rename this as "native", as this is the RTE_MACHINE that is set in these files.
This should make it clearer for people who build DPDK on a system then run it on
another one.

06371afe39 examples/netmap_compat: import netmap compatibility example
This provides a sample application and library showing how to use the
Intel(R) DPDK with basic netmap applications.

The Netmap compatibility library provides a minimal set of APIs to give the ability to
programs written against the Netmap APIs to be run with minimal changes to their
source code, using the Intel® DPDK to perform the actual packet I/O.
Since Netmap applications use regular system calls, like open(), ioctl() and
mmap() to communicate with the Netmap kernel module performing the packet I/O,
the compat_netmap library provides a set of similar APIs to use in place of those
system calls, effectively turning a Netmap application into a Intel(R) DPDK one.
The provided library is currently minimal and doesn’t support all the features that
Netmap supports, but is enough to run simple applications, such as the
bridge example included.

The application requires a single command line option:
 -i INTERFACE is the number of a valid Intel(R) DPDK port to use.
If a single -i parameter is given, the interface will send back all the traffic it
receives. If two -i parameters are given, the two interfaces form a bridge, where
traffic received on one interface is replicated and sent by the other interface.
