add kernel support for Virtual Routing and Forwarding (VRF)
https://www.kernel.org/doc/Documentation/networking/vrf.txt
The major benefits are
- higher priority ip rules (Policy Based Routing, PBR)
- iproute2 supports the vrf
- unix socket routing
- impacts only Layer 3 and above so L2 tools (e.g., LLDP) are not affected
- VRF devices allow VRFs to be nested within namespaces
Sound like the perfect companion for a routing device.
Current kernel in TOS 3.11.2 has no VRF support
