Implemented the following attributes required to successfully construct a conntrack get request: * iptuple * protoinfo * protoinfotcp * prototuple * tcp_flags * tuple Signed-off-by: Shivang K Raghuvanshi <[email protected]>
This refactors the crate to use type-safe enums for netfilter subsystems and message types, for a safer and more idiomatic API. - Introduces a `Subsystem` enum to replace raw `u8` identifiers for `NfLog` and `Conntrack` subsystems. - Introduces `ULogMessageType` and `ConntrackMessageType` enums to provide type safety for messages within each subsystem. - Makes the top-level `NetfilterMessage::message_type()` function private to guide users towards the safer pattern of matching on `NetfilterMessageInner`. - Updates the internal parsing logic in `buffer.rs` to use the new `Subsystem` enum.
