[Xen-devel] Porting linux network driver to Xen

[ravi kerur <rkerur@xxxxxxxxx>]

Hi All,

I am working on porting an existing network driver from Linux
to Xen, I understand network drivers needs netback and netfront
functionality in order to work in Xen but I am unable to nail down the
details of changes required esp. 

a. will the existing driver go into hypervisor or dom0?
b. what changes are required in TX/RX rings for DMA in existing driver and how to incorporate them into netback/netfront, 
c. handling IRQs... 

Any pointers to existing nic driver or pointer to a document would be really helpful.

Thanks
-RK
