[Qemu-devel] [PATCH 0/7 V6] VMXNET3 paravirtual NIC device implementation

[Dmitry Fleytman]

From: Dmitry Fleytman <address@hidden>

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.
