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

This patch series adds support to fix T5 adapter accessing T4 adapter registers,
issue mbox command on correct mbox for physical function, avoid dumping write
only registers, use correct length for adapter part number and support to detect
and display firmware reported errors.

The patches series is created against 'net' tree.
And includes patches on cxgb4 driver.

We have included all the maintainers of respective drivers. Kindly review the
