ynl does not handle NlError exceptions so they get reported like program
failures. Handle the NlError exceptions and report the netlink errors
more cleanly.
Example now:
Netlink error: No such file or directory
nl_len = 44 (28) nl_flags = 0x300 nl_type = 2
error: -2 extack: {'bad-attr': '.op'}
Example before:
Traceback (most recent call last):
File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 81, in <module>
main()
File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 69, in main
reply = ynl.dump(args.dump, attrs)
^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 906, in dump
return self._op(method, vals, [], dump=True)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 872, in _op
raise NlError(nl_msg)
lib.ynl.NlError: Netlink error: No such file or directory
nl_len = 44 (28) nl_flags = 0x300 nl_type = 2
error: -2 extack: {'bad-attr': '.op'}
