\section{\label{chapterB:netpfga-nftraffic}NetFPGA misses packets on nf*}
|
||||||
|
While the nf devices appear in the operating system, packets emitted
|
||||||
|
by the netpfga cannot be sniffed on the nf interfaces
|
||||||
|
directly. Instead one has to sniff packets on a physical network card
|
||||||
|
that is connected to the specific output port.
