net/mlx5e: Stringify RQ SW state in RQ devlink health diagnostics
One of the parameters that is retrieved/printed as a response to
devlink health diagnostics for rx reporter is the RQ SW state.
It's printed as a bitmap decimal number. Printing it as bitmap is
problematic and non informative.
In addition User can't count on SW state without accessing the kernel
sources (mlx5e rq state enum in en.h).
This patch prints RQ SW state in a textual representation, as a key:
value pairs, where disabled rq states will appear as '0' and enabled
ones will appear as '1'.
See below the generated output for rx health diagnostics devlink
command:
$ devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx
