Re: [PATCH net-next 08/11] netlink: specs: define input-xfrm enum in the spec

Help YNL decode the values for input-xfrm by defining
the possible values in the spec. Don't define "no change"
as it's an IOCTL artifact with no use in Netlink.

With this change on mlx5 input-xfrm gets decoded:

 # ynl --family ethtool --dump rss-get
 [{'header': {'dev-index': 2, 'dev-name': 'eth0'},
   'hfunc': 1,
   'hkey': b'V\xa8\xf9\x9 ...',
   'indir': [0, 1, ... ],
   'input-xfrm': 'sym-or-xor',                         <<<

I think this breaks rss_input_xfrm.py:

    input_xfrm = cfg.ethnl.rss_get(
        {'header': {'dev-name': cfg.ifname}}).get('input-xfrm')

    # Check for symmetric xor/or-xor
    if not input_xfrm or (input_xfrm != 1 and input_xfrm != 2):
        raise KsftSkipEx("Symmetric RSS hash not requested")

input_xfrm is now a string, the test is always skipped.
