Hi,

i would like to clarify the usage of af_packet driver. I want to 
read/send raw packets having the best response times.

A/ I am using AF_packet poll mode driver using a tap interface linked to 
the native linux igb driver

or

B/ I am using AF_PACKET poll mode driver using a tap interface linked to 
the ugb_uio pmd driver ?

or

C/ I am using AF_PACKET socket using interface linked to the ugb_uio pmd 
driver ?

which one of A,B,C ?
