[dpdk-dev] [PATCH 1/3] examples/l3fwd: increase number of routes

[pbhagavatula at marvell.com]

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

Increase the number of routes from 8 to 16 that are statically added for
lpm and em mode as most of the SoCs support more than 8 interfaces.
The number of routes added is equal to the number of ethernet devices
ports enabled through port mask.

Signed-off-by: Pavan Nikhilesh <pbhagavatula at marvell.com>

 v3 Changes: (Finally!)
 - Add FIB to the list.
 - Update release notes.
 - Update EM route addition routine and use the correct IP addresses
   DTS need not be updated as EM test doesn't use IP addresses defined
   in l3fwd.

 v2 Changes:
 - Fixup for EM mode.
