[PATCH 02/22] Firmware interface code for IB device.
From: Roland Dreier
Date: Fri Feb 17 2006 - 19:56:17 EST
From: Roland Dreier <rolandd@xxxxxxxxx>
This is a very large file with way too much code for a .h file.
The functions look too big to be inlined also. Is there any way
for this code to move to a .c file?
