During the switch to YNL, the command to list all endpoints has been
accidentally restricted to users with admin permissions.
It looks like there are no reasons to have this restriction which makes
it harder for a user to quickly check if the endpoint list has been
correctly populated by an automated tool. Best to go back to the
previous behaviour then.
mptcp_pm_gen.c has been modified using ynl-gen-c.py:
$ ./tools/net/ynl/ynl-gen-c.py --mode kernel \
--spec Documentation/netlink/specs/mptcp_pm.yaml --source \
-o net/mptcp/mptcp_pm_gen.c
The header file doesn't need to be regenerated.

Change ynl-gen-c.py to use NLA_BE16 and NLA_BE32 types to represent
big-endian u16 and u32 ynl types.
Doing this enables those attributes to have range checks applied, as
the validator will then convert to host endianness prior to validation.
The autogenerated kernel/uapi code have been regenerated by running:
./tools/net/ynl/ynl-regen.sh -f
This changes the policy types of the following attributes:
FOU_ATTR_PORT (NLA_U16 -> NLA_BE16)
FOU_ATTR_PEER_PORT (NLA_U16 -> NLA_BE16)
These two are used with nla_get_be16/nla_put_be16().
MPTCP_PM_ADDR_ATTR_ADDR4 (NLA_U32 -> NLA_BE32)
This one is used with nla_get_in_addr/nla_put_in_addr(),
which uses nla_get_be32/nla_put_be32().
IOWs the generated changes are AFAICT aligned with their implementations.
The generated userspace code remains identical, and have been verified
by comparing the output generated by the following command:
make -C tools/net/ynl/generated

This patch adds token parameter together with addr in get-addr section in
mptcp_pm.yaml, then use the following commands to update mptcp_pm_gen.c
and mptcp_pm_gen.h:
./tools/net/ynl/ynl-gen-c.py --mode kernel \
--spec Documentation/netlink/specs/mptcp_pm.yaml --source \
-o net/mptcp/mptcp_pm_gen.c
./tools/net/ynl/ynl-gen-c.py --mode kernel \
--spec Documentation/netlink/specs/mptcp_pm.yaml --header \
-o net/mptcp/mptcp_pm_gen.h

We assume in handful of places that the name of the spec is
the same as the name of the family. We could fix that but
it seems like a fair assumption to make. Rename the MPTCP
spec instead.
