I also would like to ask someone closer to the spec language double
check this.

When we recover the link at the end of the DPC handler, what is the
expected state of the endpoint?

Is it a some kind of a reset like secondary bus reset? (I assumed this
one)

Undefined?

or just plain link recovery with everything else as intact as it used
to be?
