It which supports TCP/UDP and IP transmit checksum, as well as TSO.
It has been tested with Linux (2.6.18|22|23|24)++ and Windows XP (using
the driver supplied at the intel download site).
Windows Vista recognizes it but there is no traffic.
Checksum calculation is currently naïve and unoptimized (the host
kernel does it better). But when working in conjuction to tso
the performance is drastically better.
Some figures: Linux rx 350Mbps, tx 150bps, Windows rx 700mbps, tx 100 mbps.
That will be great to have in qemu.
The e1000_hw.h is copied from Linux kernel.
Would it be possible to pick only the useful stuff from the header and
put it into the same file, rather than maintaining a copy of a linux
header (which is 3.5 bigger than the actual emulation in kLoC)? Qemu
has avoided that until now.
