<strong>XDP</strong> - actions<br />

●<br />

Currently only implement 3 basic action<br />

1) <strong>XDP</strong>_PASS:<br />

●<br />

Pass into normal network stack (could be modified)<br />

2) <strong>XDP</strong>_DROP:<br />

●<br />

Very fast drop (recycle page in driver)<br />

3) <strong>XDP</strong>_TX:<br />

●<br />

●<br />

Forward or TX-bounce back-out same interface<br />

I personally find "TX-bounce" very limiting<br />

●<br />

Cannot implement the DPDK router example<br />
