It won't do anything on 3Com NIC's, the driver doesn't support it.
Enabling it doesn't hurt anything, but it doesn't do anything when the
NIC's don't support it.
From 'man polling':
Device polling requires explicit modifications to the device drivers. As
of this writing, the dc(4), em(4), fwe(4), fxp(4), nge(4), rl(4), sis(4),
ste(4), and vr(4) devices are supported.
