It's special «status» of the network interface.
I'm not sure to understand what's that mean but if i'm not wrong : in standard
configuration it's the mothercard who manage the access of network interface
In polling mode it's the CPU to manage this.
One problem is there use lots of CPU...
For this you must add
options DEVICE_POLLING
in your kernel config
After installing the new kernel and reboot you need
/sbin/ifconfig em0 polling
and you can see in ifconfig -a
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=4b<RXCSUM,TXCSUM,VLAN_MTU,POLLING>
^^^^^^
this....
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
Of course all of that need you interface support polling, and you can see
in man polling :
Device polling requires explicit modifications to the device drivers. As
of this writing, the dc(4), em(4), fwe(4), fxp(4), ixgb(4), nge(4),
re(4), rl(4), sis(4), ste(4), vge(4), and vr(4) devices are supported,
with others in the works. The modifications are rather straightforward,
