Subject: [PATCH] netlink: specs: Add FIB rule port mask attributes

Add new port mask attributes to the spec. Example:

 # ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_rule.yaml \
	--do newrule \
	--json '{"family": 2, "sport-range": { "start": 12345, "end": 12345 }, "sport-mask": 65535, "action": 1, "table": 1}'
 None
 # ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_rule.yaml \
	--do newrule \
	--json '{"family": 2, "dport-range": { "start": 54321, "end": 54321 }, "dport-mask": 65535, "action": 1, "table": 2}'
 None
 $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_rule.yaml \
	--dump getrule --json '{"family": 2}' --output-json | jq '.[]'
