netmap is a framework for high speed packet I/O. Together with its companion VALE software switch, it is implemented as a single kernel module and available for FreeBSD, Linux and now also Windows (OSX still missing, unfortunately). netmap supports access to network cards (NICs), host stack, virtual ports (the "VALE" switch), and "netmap pipes". It can easily reach line rate on 10G NICs (14.88 Mpp

Linux has a large amount of device drivers for hardware not supported on FreeBSD, especially USB devices (see here for a related discussion). Not rarely, such drivers have been written based on information derived by protocol sniffing, reverse engineering and the like. This makes the code highly undocumented, and renders the porting effort extremely error prone. To help with this task, I decided t

Device Polling support for FreeBSD This page contains material related to some recent (Feb. 2002) work I have done to implement polling device driver support in FreeBSD. This work has been done in cooperation with ICSI in the context of the Xorp project, and in some aspects can be still considered work in progress. The code is now in the FreeBSD CVS repository both for -current and -stable, so you
