This depends on the hardware and driver.

Some drivers configure the hardware (if it can be configured that way) to
never accept broken packets, and not tell the cpu about it, so you never
should see IERRs. There's one exception however: I think ierr is incremented
by some drivers if they can't get an M_DONTWAIT mbuf to put the data in.
