Hope to get an answer / link where i can get myself clear. 1. In DPDK PMD is optimized driver for an given NIC to get maximum performance. That being the case why we are talking about DPDK supported NICs. A) My assumption is that NIC interface is standardized so that PMD should actually work with any NIC (barring some NIC specific performance tweaks) is that correct? B) if #A is correct , how can i make changes to PMD to support any NIC ? Thanks Raman
