From: Jeff Morrow <[EMAIL PROTECTED]>
The modifications and bug fixes noted below were done by Realtime Control
Works and Contemporary Control Systems, Inc, Jan 2005. They were
incorporated into the 2.6 kernel by Jeff Morrow of Sierra Analytics, Feb
2007. <[EMAIL PROTECTED]>
The changes have been tested on a Contemporary Controls PCI20U-4000.
Summary of changes:
Arc-rawmode.c:
rx():
- Fixed error in received packet lengths; 256 byte packets were
being received as 257 bytes packets.
prepare_tx():
- Fixed error in transmit length calcs; 257 byte packets were being
transmitted as 260 byte packets.
com20020.c:
com20020_check():
- We now load the SETUP2 register if the 'clockm' parameter is
non-zero, instead of checking for ARC_CAN_10MBIT. The user is
now responsible for whether or not SETUP2 is loaded. If the
clock multiplier is non-zero, this means that the user wants a
baud rate greater than 2.5Mbps. This is not possible unless the
SETUP2 register is present (COM20020D, or COM20022). So, we're
relying on the user to be smart about what kind of chip he's
dealing with...
com20020-pci.c
- Added several entries to com20020pci_id_table[].
