7de65a051f attr: mark nested attributes as NLA_F_NESTED 
Kernel 5.2 is adding stricter checking for netlink messages.
In particular, for certain API it checks now that NLA_F_NESTED flag is
set for nested attributes ([1]).

Do like libmnl, which always adds this flag ([2]). So we should do
that as well.

cf6804add6 route/link: avoid dangling pointer in rtnl_link_set_slave_type() 
- don't leave a dangling pointer, in case we unset the
  kind.

- try first to clone the string. If that fails, return early
  without modifying the link. Only start modifying the link,
  after we know it's going to succeed.

470b983546 link: macvlan fixes 
1. While parsing flags, it overrides mode.
2. Before, dump-line and dump-details are same leading that macvlan info will be shown twice while dumpping details.
   So make dump-line show nothing.
3. Add some spaces to show dump-details more prettier.

123dc07bcc nla_ok: fix overrun in attribute iteration. 
A detailed explanation is provided in the original Linux kernel commit that
fixes the bug: 1045b03e07d85f3545118510a587035536030c1c

Valgrind spotted the issue when the remaining was negative.
This bug was triggering application crashes.

1ac40683a8 route/cls: fix potential memory leak 
rtnl_act_append() cannot add more than TCA_ACT_MAX_PRIO actions to the
same list. Because of that rtnl_basic_add_action() and
rtnl_u32_add_action() should not increment the reference counter of the
given action until it is successfully added to the filter's list.

b7419a1bce lib/qdisc: avoid BUG() in "lib/route/qdisc/mqprio.c" 
BUG() raises an assertion. It seems overly harsh.

For example, rtnl_tc_data() can fail if we fail to allocate
memory. Asserting against that, makes libnl3 not out-of-memory
safe.

Just return a regular error.
