just reading the source code, yes, it appears that the card has
support for delayed rx/tx interrupts -- see RIDV and TIDV definitions
and usage in sys/dev/em/* . I don't know in what units are the values
(28 and 128, respectively), but it does appear that tx interrupts are
delayed a bit more than rx interrupts.
They are not user-configurable at the moment though, you need to rebuild
the kernel.
