https://bugzilla.kernel.org/show_bug.cgi?id=204903
Bug ID: 204903
Summary: unable to create vrf interface when ipv6.disable=1
Product: Networking
Version: 2.5
Kernel Version: 5.2.14
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
Assignee: stephen@networkplumber.org
Reporter: zhangyoufu@gmail.com
Regression: No
`ip link add vrf0 type vrf table 100` fails with EAFNOSUPPORT when boot with
`ipv6.disable=1`. There must be somewhere inside `vrf_newlink` trying to use
IPv6 without checking availablity. Maybe `vrf_add_fib_rules` I guess.

ack. I'll take a look when I get a chance. Should be a simple fix.

Not sure if it's the only problem but vrf_fib_rule() checks
ipv6_mod_enabled() for AF_INET6 but not for RTNL_FAMILY_IP6MR.
