[dpdk-dev] [PATCH v3] i40evf: fix crash when setup tx queues on vf port

[Thomas Monjalon]

> This patch fixes the issue:
> Testpmd crashed with Segmentation fault when setup tx queues on vf
> Steps for reproduce:
>   - create one vf device from i40e driver
>   - bind vf device to igb_uio and start testpmd
> 
> With debugging tools, we saw the struct i40e_vf is cleared after
> memcpy(&dev->data->dev_conf, dev_conf, sizeof(dev->data->dev_conf)) in
> rte_eth_dev_configure, which should not happen, and the pointer to
> i40e_vf isn't in the range of i40e_adapter.
> 
> The root cause is the dev_private_size in i40e virtual function driver struct
> rte_i40evf_pmd was set incorrectly.

Applied, thanks

Does it mean that Tx with i40evf never worked before?
