====================
Trivial fixes for cxgb4 driver

This patch series updates driver description for next gen. adapters, updates
firmware info., returns error for setup_rss error case, restores L1
configuration in case of FW rejects new config, updates and aligns ethtool
get stats settings, etc

 This patch series has been created against net-next tree and includes
patches on cxgb4 and cxgb4vf driver.

We have included all the maintainers of respective drivers. Kindly review
the change and let us know in case of any review comments.
