There has been a change in how firmware is loaded for Qlogic cards
(https://cgit.freebsd.org/src/commit/?id=10ed63fc06cb9902cc783ce8d0086c9aa97ed1e1),
which is included in 13.3 and since last week also 14.1. See also bug #273263
for more context.

I now built a custom kernel based on the releng/13.3 branch and reverted the
commits introducing revised firmware loading. Rebooting into the kernel with
the "old" firmware handling, everything works again and multipath devices show
up properly.

It's possible that our cards' firmware is in a non-optimal state (i.e. primary
image not active). However, we've been running in this hardware/firmware
configuration for years without any issues, so this is still a breaking change
for us. I will try to have a closer look at the firmware state next week.
