Modified from an incomplete driver for Interphase 5575 1KVC 1M card which
was originally written by Monalisa Agrawal at UNH. Now this driver
supports a variety of varients of Interphase ATM PCI (i)Chip adapter
card family (See www.iphase.com/products/ClassSheet.cfm?ClassID=ATM)
in terms of PHY type, the size of control memory and the size of
packet memory. The following are the change log and history:
Bugfix the Mona's UBR driver.
Modify the basic memory allocation and dma logic.
Port the driver to the latest kernel from 2.0.46.
Complete the ABR logic of the driver, and added the ABR work-
around for the hardware anormalies.
Add the CBR support.
Add the flow control logic to the driver to allow rate-limit VC.
Add 4K VC support to the board with 512K control memory.
Add the support of all the variants of the Interphase ATM PCI
(i)Chip adapter cards including x575 (155M OC3 and UTP155), x525
(25M UTP25) and x531 (DS3 and E3).
Add SMP support.
