[dm-devel] [PATCH v3] libmultipath: update INFINIDAT builtin config

[Arnon Yaari]

Based on the manufacturer documentation:
https://support.infinidat.com/hc/en-us/articles/202319222

INFINIDAT recommends round-robin path selector using
a different path per IO. Timeout and path recovery values
are adjusted for error-free hot upgrade scenarios.
