Sometimes flashing bitfiles to the NetFPGA will fail. A random amount
of reboots (1 to 3) and a random amount of reflashing will fix this
problem.
Below can be found the log output from the flashing process.

A successful flashing process also emits a couple of errors, however
the message ``fpga configuration failed. DONE PIN is not HIGH'' and
its succeeding lines are missing, as seen below.
After that in all cases a reboot is required; the PCI rescan in no
tested case showed the nf devices.

\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.
