vrf: Do not attempt to create IPv6 mcast rule if IPv6 is disabled
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. Fixes: e4a38c0c4b27 ("ipv6: add vrf table handling code for ipv6 mcast") Signed-off-by: David Ahern <dsahern@gmail.com> Cc: Patrick Ruddy <pruddy@vyatta.att-mail.com> Signed-off-by: David S.
