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)
