netmap for linux now available

[Luigi Rizzo]

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.

new version of netmap for linux (20120322)

[Luigi Rizzo]

I have updated the linux version of the netmap code,
specifically fixing the 'igb' driver which was not working earlier.

The code and tinycore images for today's version 20120322
are available in the same location
