> Related, is the dpaa2/dpni NIC documented anywhere?

It is not unfortunately. I tried to document code in sys/dev/dpaa2 though.
Panic is here: https://cgit.freebsd.org/src/tree/sys/dev/dpaa2/dpaa2_ni.c#n2872
Function which is actually called is there:
https://cgit.freebsd.org/src/tree/sys/dev/dpaa2/dpaa2_swp.c#n510

dpaa2_swp_wait_for_mgmt_response
(https://cgit.freebsd.org/src/tree/sys/dev/dpaa2/dpaa2_swp.c#n1125) timed out
and returned ETIMEDOUT (i.e. 60) therefore. I'm not sure why it's happened
though.
