Saeed Mahameed says:

====================
mlx5-updates-2020-07-02

Rx and Tx devlink health reporters enhancements.

1) Code cleanup
2) devlink output format improvements
3) Print more useful info on devlink health diagnose output
4) TX timeout recovery, on a single SQ recover failure, stop the loop
and reset all rings (re-open netdev).
====================
