One more question about polling,
in PfSense, if I turn on polling, but I have 1 interface that doesn't
support it, does that mean they all don't have polling turned on? Or is it
activated just for the ones that do support it, and the ones that don't use
the regular interupt system?

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.
