polling is described in polling(4) --> man 4 polling

you can give it a try
ifconfig $interface polling
or
ifconfig $interface -polling
to disable polling...

according to what JoaoBR said and proven by the manpage (man fxp), it'll
download the microcode of your Network Card (if a microcode exists).
link0 Some chip revisions have loadable microcode which can be used to
reduce the interrupt load on the host cpu. Not all boards have
microcode support. Setting the link0 flag with ifconfig(8) will
download the microcode to the chip if it is available.
However, I'm not sure what you want to do with the microcode :)
