[dpdk-dev] [PATCH v2 2/2] kni: fix igb build with kernel 4.2

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

Kernel 4.2 has introduced two new parameters in ndo_bridge_getlink,
which breaks DPDK compilation.

Linux: 7d4f8d87 ("switchdev: ad VLAN support for ports
bridge-getlink")

This patch adds the necessary checks to fix it.
