Hi,

in the attachment is a test application of the DPDK framework (dpdk.org) working with QNX6.4 and QNX6.5.
Supported are all 1GB adapters from Intel. "testpmd" is completely independend from the network infrastructure of QNX 
Neutrino.

Required is at least a dual core CPU and an 1GB Intel Ethernet adapter.

Application start for a dual core system and a single channel I210 adapter e.g.:  "testpmd -c 3 -n 1"

For a different Intel adapter must be specified its PCI sub device ID by the -D switch: "testpmd -c 3 -n1 -D nnn" ("nnn"
 hex number w/o "0x" prefix)
The application terminates with an abort() call if the requested PCI adapter couldn't be found ...

Start and stop of the "sniff function":
testpmd>set fwd rxonly
testpmd>start
testpmd>stop

Start and stop of the "UDP packet generator ":
testpmd>set fwd txonly
testpmd>start
testpmd>stop

The maximal number of packets/sec is limitted to 40.000 packets/sec by a nanospin() delay of 20us.
(Slower networks creates dropped packets .. "testpmd" must be used carefully on your own risk)

There are a lot of additional test cases included ... some are not supported because of architectural differences 
between QNX6 and Linux
Only the "Link status change" interrupt is currently supported.

Please let me know if there are issues with your 1GB Intel adapter.

Regards
