See the GNU + 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. + + Support and updates available at: ftp://ftp.iphase.com/pub/atm + +*******************************************************************************/ + +#ifndef IPHASE_H
