There is lots of trailing whitespace added by your changes.
There's also a case of spaces followed by tab characters in
the initial indentation of lines.
What makes those two things so incredibly inexcusable is that the very
tools we use to add changes to the tree _tell_ you about these things.
bundle-895.mbox:6829: trailing whitespace.
FW_STAT_TX_PORT_FRAMES_IX,
bundle-895.mbox:6879: trailing whitespace.
FW_STAT_RX_PORT_PPP7_IX,
bundle-895.mbox:6985: trailing whitespace.
FW_STAT_LB_PORT_FRAMES_IX,
bundle-895.mbox:6986: trailing whitespace.
FW_STAT_LB_PORT_BCAST_IX,
bundle-895.mbox:9918: trailing whitespace.
int ret;
bundle-895.mbox:10135: space before tab in indent.
if (mac) {
bundle-895.mbox:12533: trailing whitespace.
* prevent further unmapping attempts.
bundle-895.mbox:18605: trailing whitespace.
bundle-895.mbox:18981: trailing whitespace.
dev_info(adap->pdev_dev,
bundle-895.mbox:19266: trailing whitespace.
fatal: 10 lines add whitespace errors.
Such automated clerical issues should be taken care of before you even
submit this for "review". It's the same as making sure the code
compiles.
Also you should use the netdev_*() message logging helpers added
by Joe Perches instead of your local CMSG_*() hacks.
Finally, this V_*, S_*, F_* naming scheme for register values is
backwards and if anything very non-standard. Please use normal macro
names for these things so you code is more readable by people who
have to look at all of the other device drivers in the tree not
just your's.

I apologize for the whitespace damage, I'll fix that asap.

I saw those patches going in but didn't use them because the messages in
the driver are almost always about the adapter as a whole and not about
any one of its ports (it has several). The CH_* macros in the driver
expand to the dev_* family of logging helpers. I could replace them
with the netdev_* family but the netdev used for them will tend to be
arbitrary and I didn't think this was very appropriate. Let me know.

The first letter in these macros indicates what the macro is about (S
for shift, M for mask, F for flag, etc) and is the same scheme used in
previous Chelsio drivers. I can replace them if you want but I wanted
to mention that there's a reasoning for their naming. Would it help to
add a comment at the top explaining what the first letter designates?
Thanks for the comments.
