The merge window is in 3 weeks or so, so this can wait.
I'm worried we'll find out later that the current queue reset
implementation in bnxt turns out to be insufficient. And we'll
be stuck with yet another close/open in this driver.
While we talk about affinity settings in bnxt -- it'd be great
if it maintained the mapping and XPS settings across reconfiguration
(like queue count changes or attaching XDP).
