Hi Stefan,
The steps you did are correct:
* Enable CONFIG_RTE_LIBRTE_IEEE1588=y in the config.
* Compile the testpmd application (this happens as part of the default
compile):
make -j T=x86_64-native-linuxapp-gcc install
Then you can run testpmd with ieee1588 forwarding on as follows (or similar.
Adjust coremask to suit):
sudo ./x86_64-native-linuxapp-gcc/app/testpmd -c 300 -n 4 \
-- --port-topology=chained --txqflags=0 --forward-mode=ieee1588
Note:
The --txqflags=0 is required to ensure ieee1588 support in the "full
featured" TX path.
If you send the correct l2 ptp packets they should generate a text output from
testpmd
Add '-i' after '--' to enter interactive mode in testpmd.
You can also set IEEE1588 mode from within testpmd as follows:
testpmd> set fwd ieee1588
Set ieee1588 packet forwarding mode
Note: if you don't see the ieee1588 mode it usually means that
CONFIG_RTE_LIBRTE_IEEE1588 wasn't configured.
Best of luck,
John.
