 Is it possible to implement page mechanism in Network drivers

 Is there any sample driver which implemented this in opensource.

Hi Rayma,

why do you want to do this, i.e. in which ways are the DDI functions 
insufficient for your driver ?

Maybe Rayma is requesting IOMMU.

Hi,
   I am just guessing that Using page machanism i can
increase the through put and performance of my 10gig network
driver .As DDI interface involves so much binding and allocating of
handles .
   In Linux paging gives better performance than normal
allocation , so i am looking in that way in solaris .
