The linux-rex module relies on the Hyperscan database serialization feature.
Hyperscan is designed to be modular. The libhs_runtime.a provides
the regular expressions engine that loads a compiled expression and
performs the scanning.
The libhs.a module provides configuration facilities by compiling
textual representation of a regular expression into the database format
the runtime can use.
The module doesn't support batch operations, as XDP doesn't provide that feature.
See the installation guide.
