DPDK Version: 21.11
Firmware version : 22.32.1010

We are trying to use the DPDK tx scheduling feature on a ConnectX6 DX adapter. We experience some issues with the feature not working.

The test is using Test-pmd in txonly mode.

Here are the command used:

sudo ./dpdk-testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=1 --eth-peer=0,01:00:5e:00:00:08 --tx-ip=,
testpmd> set fwd txonly
testpmd> set burst 64
testpmd> set txtimes 1000000,10000

By doing this I expect the feature working. Am i missing something ?

I also added a print in txonly.c and clearly sees that the feature is not enabled

dynf = rte_mbuf_dynflag_lookup
if (dynf >= 0)
timestamp_mask = 1ULL << dynf;
dynf = rte_mbuf_dynfield_lookup
if (dynf >= 0)
timestamp_off = dynf;

both function ( rte_mbuf_dynfield_lookup and rte_mbuf_dynflag_lookup) returns -1

I also tried to enabled the feature.

testpmd> port config 0 tx_offload send_on_timestamp on
but when doing this DPDK tells me that I don't have these offload capabilities

Hope you will be able to help me.
