Well, if Changli didnt post - there would be no discussion ;->
The message was lost in the translation somewhere; events such as
patches sometimes serve as good reminders.

Indeed - this is working against something buggy. But it has happened
often in the past. And the likelihood of there being a few bad ones
in the train of packets when this occurs is high. But there are many
packets there that wont suffer this sympton - so the only fair scheme is
to check all. Note: a BUG() seems unreasonable and the deferring  serves
as a throttling scheme.
What do you have in mind?

cheers,
jamal
