Re: [dpdk-users] Reg PMD & NIC

[Nikhil Nanal <nanal@usc.edu>]

Hi, 

I guess DPDK works only for Intel NICs. Also, there are a variety of NIC cards from Intel. 
The drivers are generally specific to a NIC card or a family of NIC cards. The DPDK, replaces the existing NIC drivers with its PMD drivers, , but these PMDs are
only compatible with some specified class of Intel NIC cards and so there are only some supported NICs but not all. 

thanks
Nikhil
