|
|
|
|
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.
