if_cxgb.ko driver doesn't work wit latest chelsio firmware - 7.12. 

I got this message:

found newer FW version(7.12), driver compiled for version 7.11

NICs are being loaded as interfaces. However when I plug the cable it's shown as no carrier.

Patched the file with the latest firmware 7.12. 
Link is now changing to up, haven't tasted it further.

Can this be closed based on comment 1?

It is not clear what the original problem was.  The "found newer FW ..."
message is purely informational and the driver carries on normally with
attach after logging that message.  Changing the firmware bundled with
the driver to match the card should not have made a difference.

Yes but please check the last line of the initial description:

"NICs are being loaded as interfaces. However when I plug the cable it's shown as no carrier."

And the last sentence: 

"when I plug the cable it's shown as no carrier."

This is the original problem.

I get that the link did not come up originally.  My point is that adding
the 7.12 firmware to the driver should not have made any difference.  It
just suppressed the informational message about there being a new firmware
on the card.  The rest of driver attach should be identical in both cases.
And yet the link came up the second time but not the first?  That's hard
to explain.

I think this can be closed as "unable to reproduce" given that the driver
was using the same firmware in both the scenarios but link didn't come up
the first time, for reasons unknown.
