Message-ID: <20120312230809.GA45615@onelab2.iet.unipi.it> Date: Tue, 13 Mar 2012 00:08:09 +0100 From: Luigi Rizzo <rizzo@....unipi.it> To: netdev@...r.kernel.org Subject: netmap for linux now available just in case you might be interested... i have recently completed a linux port of the netmap framework. Code, documentation and PicoBSD/Tinycore bootable images are at http://info.iet.unipi.it/~luigi/netmap/ Netmap is a device-independent framework for packet generation and capture from user space; it can do line rate at 10Gbit/s (14.88Mpps) with just one core at about 1GHz. Netmap relies on a kernel module (netmap_lin.ko) and slightly modified device drivers (about 4-500 lines per driver). It requires no kernel patches apart from device drivers (and abusing the ax25 field in struct netdevice). Userspace programs can use the native API (documented in netmap.4) or a libpcap emulation library. It has been integrated in FreeBSD last fall, and the linux version uses mostly the same code plus a bit of glue to adapt the BSD<->linux kernel ABI. The current version supporting the ixgbe and e1000/e1000e driver. Patches for other devices (igb, r8169, forcedeth) are avaiable but untested. cheers luigi -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
