Update of used->idx and read of avail->flags could be reordered.
Memory fence should be used to ensure the order, otherwise guest could see
a stale used->idx value after it toggles the interrupt suppression flag.
After guest sets the interrupt suppression flag, it will check if there
is more buffer to process through used->idx. If it sees a stale value,
it will exit the processing while host won't send interrupt to guest.

The introduction of uio_pci_generic broke interrupt handling with
igb_uio. The igb_uio device uses the kernel read/write method to
enable disable IRQ's; the uio_pci_generic has to use PCI intx
config read/write to enable disable interrupts.
Since igb_uio uses MSI-X the PCI intx config read/write won't
work.

The script relpath.sh returns the relative path of the first directory
from the second directory. It is used to generate relative symlinks,
which can be useful if the build directory is embedded in the dpdk
directory: the whole dpdk can be moved without breaking the links,
which is helpful for an installation.
In case the build directory is a symlink, the script was not generating
the proper relative path. Fix this by calling "readlink -f" on the
arguments.

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.
