[dpdk-dev] [Bug 814] Intel PMD both i40 and iavf send OP_DISABLE_VLAN_STRIPPING and it not mandatory

[spyroot]

The second issue is in CONFIG_RSS_LUT.

That *VIRTCHNL_OP_CONFIG_RSS_LUT*
<http://code.dpdk.org/dpdk/v20.05/ident/VIRTCHNL_OP_CONFIG_RSS_LUT>; is
optional so if it returns ret it must be handled correctly.


int

*iavf_configure_rss_lut*
<http://code.dpdk.org/dpdk/v20.05/ident/iavf_configure_rss_lut>(struct
*iavf_adapter* <http://code.dpdk.org/dpdk/v20.05/ident/iavf_adapter>
*adapter)

{

        struct *iavf_info*
<http://code.dpdk.org/dpdk/v20.05/ident/iavf_info> *vf =
*IAVF_DEV_PRIVATE_TO_VF*
<http://code.dpdk.org/dpdk/v20.05/ident/IAVF_DEV_PRIVATE_TO_VF>(adapter);

        struct *virtchnl_rss_lut*
<http://code.dpdk.org/dpdk/v20.05/ident/virtchnl_rss_lut> *rss_lut;

        struct *iavf_cmd_info*
<http://code.dpdk.org/dpdk/v20.05/ident/iavf_cmd_info> args;

        int len, err = 0;



        len = sizeof(*rss_lut) + vf->vf_res->rss_lut_size - 1;

        rss_lut = *rte_zmalloc*
<http://code.dpdk.org/dpdk/v20.05/ident/rte_zmalloc>("rss_lut", len,
0);

        if (!rss_lut)

                return -ENOMEM;



        rss_lut->vsi_id = vf->vsi_res->vsi_id;

        rss_lut->lut_entries = vf->vf_res->rss_lut_size;

        *rte_memcpy*
<http://code.dpdk.org/dpdk/v20.05/ident/rte_memcpy>(rss_lut->lut,
vf->rss_lut, vf->vf_res->rss_lut_size);



        args.ops = *VIRTCHNL_OP_CONFIG_RSS_LUT*
<http://code.dpdk.org/dpdk/v20.05/ident/VIRTCHNL_OP_CONFIG_RSS_LUT>;

        args.in_args = (*u8*
<http://code.dpdk.org/dpdk/v20.05/ident/u8> *)rss_lut;

        args.in_args_size = len;

        args.out_buffer = vf->aq_resp;

        args.out_size = *IAVF_AQ_BUF_SZ*
<http://code.dpdk.org/dpdk/v20.05/ident/IAVF_AQ_BUF_SZ>;



        err = *iavf_execute_vf_cmd*
<http://code.dpdk.org/dpdk/v20.05/ident/iavf_execute_vf_cmd>(adapter,
&args);

        if (err)

                *PMD_DRV_LOG*
<http://code.dpdk.org/dpdk/v20.05/ident/PMD_DRV_LOG>(ERR,

                           "Failed to execute command of OP_CONFIG_RSS_LUT");



        *rte_free* <http://code.dpdk.org/dpdk/v20.05/ident/rte_free>(rss_lut);

        return err;
