Subject: [PATCHv4 net-next 3/4] net: team: use policy generated by YAML spec
generated with:
$ ./tools/net/ynl/ynl-gen-c.py --mode kernel \
> --spec Documentation/netlink/specs/team.yaml --source \
> -o drivers/net/team/team_nl.c
$ ./tools/net/ynl/ynl-gen-c.py --mode kernel \
> --spec Documentation/netlink/specs/team.yaml --header \
> -o drivers/net/team/team_nl.h
The TEAM_ATTR_LIST_PORT in team_nl_policy is removed as it is only in the
port list reply attributes.
