These rules are per-VNIC, i.e. only apply to the current driver. If a rule matches, then the packet is considered to have the corresponding encapsulation type, and the inner packet is parsed. It is up to the driver to ensure that overlapping rules are not inserted. (If a packet would match multiple rules, a random one of them will be used.) A rule with the exact same match criteria may not be inserted twice (EALREADY). Only a limited number MATCH_FLAGS values are supported, use MC_CMD_GET_PARSER_DISP_INFO with OP OP_GET_SUPPORTED_VNIC_ENCAP_RULE_MATCHES to get a list of supported combinations. Each driver may only have a limited set of active rules - returns ENOSPC if the caller's table is full.

We are allowing base files to keep their original syntax (as long as it 
is consistent within), but whole above comment as single line looks a 
little excessive, can you please fix it?

ditto
