Summary iavf : max_rtx_queues not true when network adaptor not suppo= rt large vf

Target Milestone --- 

our app code use dev_info->max_=
tx_queues to check the max queue.
we get dev_info->max_rx_queues=3D265(IAVF_MAX_NUM_QUEUES_LV), but when w=
e try to
requet 30 tx queue, we got  iavf_dev_configure(): large VF is not supported.
by check code we find that :
max queue number of  nomal vf  is 16 (IAVF_MAX_NUM_QUEUES_DFLT).

may be the code need to change like this :
drivers/net/iavf/iavf_ethdev.c:=20=20=20=20=20=20=20=20=20
static int
iavf_dev_info_get(struct rte_eth_dev *dev, struct rte_eth_dev_info *dev_inf=
o)
{
        struct iavf_adapter *adapter =3D
                IAVF_DEV_PRIVATE_TO_ADAPTER(dev->data->dev_private);
        struct iavf_info *vf =3D &adapter->vf;

        if (adapter->closed)
                return -EIO;

        dev_info->max_rx_queues =3D IAVF_MAX_NUM_QUEUES_LV;
        dev_info->max_tx_queues =3D IAVF_MAX_NUM_QUEUES_LV;
+       if (vf->vf_res->vf_cap_flags & VIRTCHNL_VF_LARGE_NUM_QPAI=
RS){
+               dev_info->max_rx_queues =3D IAVF_MAX_NUM_QUEUES_DFLT;
+               dev_info->max_tx_queues =3D IAVF_MAX_NUM_QUEUES_DFLT;=20=
=20=20=20=20
+       }
