Command / instruction:
Start testpmd with command line as:
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x1fffffffff -n 4 -- -i
--coremask=0x400 --portmask=0x3 --nb-cores=2 --enable-rx-cksum
--disable-hw-vlan --disable-rss --rxd=1024 --txd=1024 --rxfreet=0
Start ports:
set fwd cusm
start
Expected test result:
Testpmd can startup.
