comment = "Userland netmap support"
desc = <<EOD
The netmap(4) kernel facility allows userland applications to send and receive
data on a network interface using a memory-mapped ring buffer. netmap offers
significantly better performance for this task than similar interfaces such as
bpf(4), tap(4), or raw sockets.
This package provides libnetmap, a library used by applications to interact
with netmap, and valectl(8), a utility to manage vale(4) network switches.
