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.
