====================
eth: fbnic: Cleanup macros and string function

We have received some feedback that the macros we use for reading FW mailbox
attributes are too large in scope and confusing to understanding. Additionally
the string function did not provide errors allowing it to silently succeed.
This patch set fixes theses issues.
