Yes, in drivers/net/Kconfig:
config NET_VRF
tristate "Virtual Routing and Forwarding (Lite)"
depends on IP_MULTIPLE_TABLES
depends on NET_L3_MASTER_DEV
depends on IPV6 || IPV6=n
depends on IPV6_MULTIPLE_TABLES || IPV6=n
---help---
This option enables the support for mapping interfaces into VRF's. The
support enables VRF devices.
