Deleting the old firmware is a bad idea.  You've haven't modified the driver in
net or net-next to use the new firmware, and until you do, kernels won't be able
to find the firmware the driver is requesting.  You should make firmware changes
addative.  Add new versions of firmware, but keep the old ones (at least for a
while).  Thank you for moving cxgb4 to a versioned firmware file though.  I
presume there is a pending update to change the FW_FNAME definition to pending?

Hi Neil,

Thank you for the review. I have updated the patch series with the 
following changes:
- Rename the existing t4fw.bin file as t4fw-1.3.10.0.bin
- Add t4fw.bin as a symlink to the latest t4fw revision.

The driver looks up "t4fw.bin", the symlink allows updates of the FW 
without actually modifying the driver source.
Also, if the firmware revision under /lib/firmware/cxgb4/t4fw.bin is 
more recent than the adapter's embedded FW,
the driver will update it. The FW revisions are forward compatible.

The following changes since commit 15888a2eab052ac3d3f49334e4f6f05f347a516e:

   bnx2x: Adding FW 7.0.29.0 (2011-10-24 16:31:44 +0200)

Thats fine, I presume then we can expect a commit to the cxgb3 driver shortly,
updatnig the FW_VERSION_MINOR macro?

Hi Ben, David,

I just realize that the rules to submit patches or pull requests to

Are there any versions of the cxgb4 driver that will specifically
request cxgb4/t4fw-1.3.10.0.bin?  If not, what's the point of keeping it
around after changing the cxgb4/t4fw.bin symlink?

I think the right thing to do is update the chelsio driver to do exactly that,
request a specific version of firmware (or range of versions), like most other
drivers do.  That way a single system can boot kernels with varying driver
versions, each of which may require a different firmware api level.

Hi Ben,

I originally removed cxgb4/t4fw-1.3.10.0.bin when I posted the request 
against David's tree.
Subsequent review from Neil requested to keep it around at least for a 
while (https://lkml.org/lkml/2012/2/11/61).
Either way is fine to me.

Cheers,
Divy
