steer

Overview ¶

Command filter receives with a filter and reports what arrives, by destination port, so you can see the filter doing its job.

It needs a backend that steers, which today means mlx5, so build it with -tags mlx5. AF_PACKET has no filter: it is a tap, and the kernel sees every packet whatever a socket takes.
