Hi,
Is there a good example that uses the virtio network interfaces direct? ie. an
application that uses ‘assign-net’ and talks directly to the network interface
code in OSv?
I’m looking for a sample I can learn from.
Cheers,
Rick

Ah, ok. I guess something like DPDK may be instructive in that respect.

The pfil_add_hook() functionality may be sufficient, thanks! I’ll give it a go.

It’d be nice if there was a similar way to get packets as they arrive. The

Is there an equivalent to SO_BINDTODEVICE? I’m trying to get an implementation
of VRRP working and the first issue is that the sending socket requires to be
bound to the appropriate interface.
After that, I’ll probably run into issues relating to the virtual IP and mac
address - but the SO_BIN
