I wish I could help, but I have little knowledge about the device 
polling capability.  Did you intend to ask Michael?

However, I can say that according to polling(4) man page, neither ix(4) 
nor sfxge(4) are listed as supported by it.  I saw no change regarding 
pf with polling in the kernel.  Finally, polling is recommended 
(somewhere?) for slower hardware.  If you are using a 10Gb adapter, you 
most likely have a faster system that does not need it.

You should ask in a separate E-mail thread if you have issues with that 
driver or hardware.
