Hi Dpdk Champs,
I am facing an issue while bringing bonding on VM having vmxnet3 interfaces.
Below error is coming in the log -
PMD: bond_ethdev_start(1959) - bonded port (2) failed to reconfigure slave
device (0).
Please suggest.
Thanks,
Chetan Bhasin

Any other error messages? There's really only one path out of
slave_configure() that doesn't emit another error message and
that's slave_configure_slow_queue. You need to set dedicated_queues to
be enabled to see that happen.

Thanks for your reply .
The issue coming in function "vmxnet3_dev_tx_queue_setup"
below if condition is true because "tx_conf->txq_flags is coming as 0"
if ((tx_conf->txq_flags & ETH_TXQ_FLAGS_NOXSUMSCTP) !=
ETH_TXQ_FLAGS_NOXSUMSCTP) {
PMD_INIT_LOG(ERR, "SCTP checksum offload not supported");
return -EINVAL;
}
Regards,
Chetan Bhasin

Hi Chetan,
In v17.11, all Tx offloads are enabled by default and can be disabled via
tx_conf->txq_flags.
Above code says PMD is not supporting SCTP checksum offload but you are
requesting it, by passing "txq_flags == 0", and PMD fails.
You need to pass at least "txq_flags = ETH_TXQ_FLAGS_NOXSUMSCTP" to be able to
use vmxnet3.

Thanks a lot
Let me check in vpp's DPDK plugin what value is passed.
Thanks,
