Hi, Can someone suggest the proper configuration required to test jumbo frames along with scatter mode using testpmd?
I'm running the tool as follow: . sudo ./testpmd -l 0-3 -n 4 -- -i --max-pkt-len=9600 --enable-scatter --txd=512 --rxd=512 --forward-mode=flowgen . then attempting to set the packet length: . testpmd> set txpkts 9036 length[0]=9036 > mbuf_data_size=2176 - give up . According to the documentation (https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html), the option txpkts should configure: . Set TX segment sizes or total packet length. Valid for tx-only and flowgen forwarding modes. . So I was expecting to be able to set the packet length in this way, but somehow it doesn't work and when I hit start the packets have always a length of 60 bytes: . src=00:01:02:03:04:00 - dst=00:01:02:03:04:01 - type=0x0800 - length=60 - nb_segs=1 - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN L4_UDP - sw ptype: L2_ETHER L3_IPV4 L4_UDP - l2_len=14 - l3_len=20 - l4_len=8 - Send queue=0x0 . I've attempted to set the queue capabilities (scatter and JF) by hand with: . testpmd> port config 1 rx_offload scatter on testpmd> port config 1 rx_offload jumbo_frame on . (repeated for both port) but this doesn't helped, so, how do I test a card using testpmd with packets bigger than 2176? Thanks -- BR, Filip +48 666 369 823
