+Limitations
+-----------
 
-Using the SZEDATA2 PMD
-----------------------
+The SZEDATA2 PMD does not support operations related to Ethernet ports
+(link_up, link_down, set_mac_address, etc.).
 
-From DPDK version 16.04 the type of SZEDATA2 PMD is changed to PMD_PDEV.
-SZEDATA2 device is automatically recognized during EAL initialization.
-No special command line options are needed.
+NFB cards employ multiple Ethernet ports.
+Until now, Ethernet port-related operations were performed on all of them
+(since the whole card was represented as a single port).
+With NFB-200G2QL card, this is no longer viable (see above).
 
-Kernel modules have to be loaded before running the DPDK application.
+Since there is no fixed mapping between the queues and Ethernet ports, and since
+a single card can be represented as two ports in DPDK, there is no way of
+telling which (if any) physical ports should be associated with individual
+ports in DPDK.
