As already pretested this patch I got from Dmitry now I successfully
tested it on Fedora 16 and Knoppix 6.7 (retested again successfully).
netio performance on localhost (ok):

Since hw passed also WHQL tests it is IHMO ready for commit :-)

This set of patches implements VMWare VMXNET3 paravirtual NIC device.
The device supports of all the device features including offload capabilties,
VLANs and etc.
The device is tested on different OSes:
Fedora 15
Ubuntu 10.4
Centos 6.2
Windows 2008R2
Windows 2008 64bit
Windows 2008 32bit
Windows 2003 64bit
Windows 2003 32bit
Changes in V6:
Fixed most of problems pointed out by Michael S. Tsirkin
The only issue still open is creation of shared place
with generic network structures and functions. Currently
all generic network code introduced by VMXNET3 resides in
vmxnet_utils.c/h files. It could be moved to some shared location however
we believe it is a matter of separate refactoring as there are a lot of
copy-pasted
definitions in almost every device and code cleanup efforts requred in order
to create truly shared codebase.
