[PATCH V2 net-next 04/10] net: hns3: remove useless proto_support field in struct hclge_fd_cfg

From: Huazhong Tan
Date: Sun Apr 19 2020 - 22:19:29 EST


From: Guojia Liao <liaoguojia@xxxxxxxxxx>

proto_support field in struct hclge_fd_cfg shows what protocols
in flow direct table are supported now. It is unnecessary since
checking which one is unsupported will be more efficient,
so this patch removes it.
