The hardware supports up to 8 flex parser configurations.
Some of them can be utilized internally by firmware, depending on
the configured profile ("FLEX_PARSER_PROFILE_ENABLE" in NV-setting).
The firmware does not report in capabilities how many flex parser
configuration is remaining available (this is device-wide resource
and can be allocated runtime by other agents - kernel, DPDK
applications, etc.), and once there is no more available parsers
on the parse object creation moment firmware just returns an error.
