From: David Ahern <dsahern@xxxxxxxxx> [ Upstream commit dac91170f8e9c73784af5fad6225e954b795601c ] A user reported that vrf create fails when IPv6 is disabled at boot using 'ipv6.disable=1': https://bugzilla.kernel.org/show_bug.cgi?id=204903 The failure is adding fib rules at create time. Add RTNL_FAMILY_IP6MR to the check in vrf_fib_rule if ipv6_mod_enabled is disabled.
