/**
|
|
* @file rte_bpf_ethdev.h
|
|
* @b EXPERIMENTAL: this API may change without prior notice
|
|
*
|
|
* API to install BPF filter as RX/TX callbacks for eth devices.
|
|
* Note that right now:
|
|
* - it is not MT safe, i.e. it is not allowed to do load/unload for the
|
|
* same port/queue from different threads in parallel.
|
|
* - though it allows to do load/unload at runtime
|
|
* (while RX/TX is ongoing on given port/queue).
|
|
* - allows only one BPF program per port/queue,
|
|
* i.e. new load will replace previously loaded for that port/queue BPF program.
|
|
* Filter behaviour - if BPF program returns zero value for a given packet,
|
|
* then it will be dropped inside callback and no further processing
|
|
* on RX - it will be dropped inside callback and no further processing
|
|
* for that packet will happen.
|
|
* on TX - packet will remain unsent, and it is responsibility of the user
|
|
* to handle such situation (drop, try to send again, etc.).
