What is confusing is that the sentence makes it sound like it's some
generic driver that can be used for any PCS, whereas in reality it is
_this_ XPCS driver which is not generic.

"This driver will support setting a custom device ID in a future patch."
or explicitly state the summary line of the patch concerned so one can
refer to it. Future references are difficult to find whether they're in
email and especially once they're merged into git.

You need to adjust your attitude - I did exactly that. There was
something which I didn't understand, so I raised the issue. Sorry
for spotting a problem, but do you always get arsey when a reviewer
picks up on something wrong? If that's your attitude, then for this
entire series: NAK.
