+/******************************************************************************
+ Device driver for Interphase ATM PCI adapter cards
+ Author: Peter Wang <pwang@iphase.com>
+ Interphase Corporation <www.iphase.com>
+ Version: 1.0
+ iphase.h: This is the header file for iphase.c.

+ General Public License for more details.
+
+ 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 followings 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.
