H A Dmlx5_health.c5169fb81 Wed May 08 10:30:47 GMT 2019 Hans Petter Selasky <hselasky@FreeBSD.org> Protect from infinite sw-reset loop in mlx5core.

Avoid an infinite software firmware reset loop that may be caused by a
hardware bug by limiting the maximum number of resets.
The counter between resets is reset by request for reset, and not by a
successful reset.
The interval between two resets can be configured via sysctl:
hw.mlx5.sw_reset_timeout
which is global to all mlx5 devices in the system.
