2094	"""proxy_protocol"" parameter in directive ""listen"" is incompatible with ""udp""."	zhoushulin1992@…		"
When users try to use udp protocol in directive ""listen"", the parameter ""proxy_protocol"" should not be used. But no message is mentioned in the doc of directive ""listen"" in https://nginx.org/en/docs/stream/ngx_stream_core_module.html#listen. I think we should add this information in the doc. A similar situation also occur in parameter ""ssl"", ""so_keepalive"", and ""backlog"" in directive ""listen""."	enhancement	closed	minor		documentation	1.18.x	wontfix		zhoushulin1992@…	Linux xlarge 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.18.0
