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'}, <<<
'flow-hash': {'ah4': {'ip-dst', 'ip-src'},
'ah6': {'ip-dst', 'ip-src'},
'esp4': {'ip-dst', 'ip-src'},
'esp6': {'ip-dst', 'ip-src'},
'ip4': {'ip-dst', 'ip-src'},
'ip6': {'ip-dst', 'ip-src'},
'tcp4': {'l4-b-0-1', 'ip-dst', 'l4-b-2-3', 'ip-src'},
'tcp6': {'l4-b-0-1', 'ip-dst', 'l4-b-2-3', 'ip-src'},
'udp4': {'l4-b-0-1', 'ip-dst', 'l4-b-2-3', 'ip-src'},
'udp6': {'l4-b-0-1', 'ip-dst', 'l4-b-2-3', 'ip-src'}}
