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 ?
