Hi Stephen,
I love your patch! Yet something to improve:
[auto build test ERROR on net-next/master]
url:
https://github.com/0day-ci/linux/commits/Stephen-Hemminger/ipv6-report-errors-for-iftoken-via-netlink-extack/20210407-074055
base: https://git.kernel.org/pub/scm/linux/kernel/git/davem/
From: Stephen Hemminger
Setting iftoken can fail for several different reasons but there
and there was no report to user as to the cause. Add netlink
extended errors to the processing of the request.
This requires adding additional argument through rtnl_af_ops
set_link_af callback.
