SUPPORTED DEVICES
Device polling requires explicit modifications to the device drivers. As
of this writing, the bge(4), dc(4), em(4), fwe(4), fwip(4), fxp(4),
ixgb(4), nge(4), re(4), rl(4), sf(4), sis(4), ste(4), vge(4), vr(4), and
xl(4) devices are supported, with others in the works. The modifications
are rather straightforward, consisting in the extraction of the inner
part of the interrupt service routine and writing a callback function,
*_poll(), which is invoked to probe the device for events and process
them. (See the conditionally compiled sections of the devices mentioned
above for more details.)
As in the worst case the devices are only polled on clock interrupts, in
order to reduce the latency in processing packets, it is not advisable to
decrease the frequency of the clock below 1000 Hz.
