Hello!

I have next situation: my toy DPDK app runs OK with  (lspci) :

01:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit 
SFI/SFP+ Network Connection (rev 01)
01:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit 
SFI/SFP+ Network Connection (rev 01)

02:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit 
SFI/SFP+ Network Connection (rev 01)
02:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit 
SFI/SFP+ Network Connection (rev 01)

I added 710:
04:00.0 Ethernet controller: Intel Corporation Ethernet Controller X710 
for 10GbE SFP+ (rev 02)
04:00.1 Ethernet controller: Intel Corporation Ethernet Controller X710 
for 10GbE SFP+ (rev 02)

So, now getting error:

Is there what I'm need to check ?


Thanks in advance!

The message says it all:
you're requesting Tx offloads not supported by the HW.
0x10000 == RTE_BIT(16) == RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE,
which is supported by i40e but not ixgbe PMD.
Can it be that you use rte_eth_dev_info.tx_offload_capa from i40e port
to fill txmode.offloads for ixgbe port by mistake?
