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

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

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