[dpdk-dev] [PATCH] app/testpmd: fix tx vlan and qinq insert enable

[dpdk-dev] [PATCH] app/testpmd: fix tx vlan and qinq insert enable

[Nithin Kumar Dabilpuram]

Tx VLAN & QinQ insert enable need not depend on
Rx VLAN offload ETH_VLAN_EXTEND_OFFLOAD. Also enable
DEV_TX_OFFLOAD_VLAN_INSERT for tx_qinq_set() as it takes
both vlan id's.

Technically two different but related fix, should it be two separate patches,
what do you think?

Here I think intention is if QINQ is enabled 'tx_vlan_id' & 'tx_vlan_id_outer'
should be set by tx_qinq_set() not 'tx_vlan_set', and check is for that.

What do you think keeping same logic?
But of course check should be if 'ports[port_id].dev_conf.txmode.offloads' has
'DEV_TX_OFFLOAD_QINQ_INSERT' instead of above check.

Wrong headline lowercase:

The commit line does not seem correct as it is actually fixing the tx_qinq_set() function.

Since tx_vlan_set() and tx_qinq_set() are they themselves are resetting/setting those flags in 'ports[port_id].dev_conf.txmode.offloads', 
do you think having such a check before clearing and setting flags be consistent ?
Current behavior is to override last setting with new setting. All the settings could be completely disabled by cmdline "tx vlan reset"

When QINQ offload is enabled:
  'vlan_id' & 'vlan_id_outer' should be set together via 'tx_qinq_set()'
  This is "tx_vlan set <port_id> <vlan_id> <outer_vlan_id>" command

When VLAN offload is enabled:
  'vlan_id' should be set via 'tx_vlan_set()'
  This is "tx_vlan set <port_id> <vlan_id>" command

basically, the check above is to prevent to setting only 'vlan_id' once both
"<vlan_id> <outer_vlan_id>" set.

I don't know the main reason of the intention of current implementation, I
assume it is to help user to prevent make mistake.

This patch is to prevent 'ETH_VLAN_EXTEND_OFFLOAD' dependency, I believe it
makes sense.

But my concern this patch is also changing above intention silently, and if we
should keep the intention?

If you think that QINQ protection is also should removed, that is OK, only
please make it separate patch with describing the impact.

Yes, it makes sense to remove the 'ETH_VLAN_EXTEND_OFFLOAD' dependency for VLAN/QINQ insertion.
It's the 92ebda07ee58 ("app/testpmd: add qinq stripping and insertion") that introduced this logic,
6a34f91690d0 ("app/testpmd: fix error message when setting Tx VLAN") fixed the port id check issue.

I think the original intention is to avoid mixing up VLAN insertion and QINQ insertion, since both are changing the vlan_id.
If user set QINQ first and then changes to just VLAN insertion, but he/she gets no warning about QINQ config still exists.
From this point of view, VLAN insertion and QINQ insertion should be mutual exclusive.

And like Ferruh said, this check should be like: if (ports[port_id].dev_conf.txmode.offloads & DEV_TX_OFFLOAD_QINQ_INSERT)

Yes, it makes sense to remove the 'ETH_VLAN_EXTEND_OFFLOAD' dependency for VLAN/QINQ insertion.
It's the 92ebda07ee58 ("app/testpmd: add qinq stripping and insertion") that introduced this logic,
6a34f91690d0 ("app/testpmd: fix error message when setting Tx VLAN") fixed the port id check issue.

I think the original intention is to avoid mixing up VLAN insertion and QINQ insertion, since both are changing the vlan_id.
If user set QINQ first and then changes to just VLAN insertion, but he/she gets no warning about QINQ config still exists.
From this point of view, VLAN insertion and QINQ insertion should be mutual exclusive.

And like Ferruh said, this check should be like: if (ports[port_id].dev_conf.txmode.offloads & DEV_TX_OFFLOAD_QINQ_INSERT)

Xiao

[dpdk-dev] [PATCH v4 2/2] app/testpmd: fix Tx QinQ set

[Nithin Dabilpuram]

From: Nithin Dabilpuram <ndabilpuram@marvell.com>

Enable DEV_TX_OFFLOAD_VLAN_INSERT also along with
DEV_TX_OFFLOAD_VLAN_QINQ in tx_qinq_set() as it takes
both vlan id's as arguments.

Hi Ferruh,

Yes, our mail server had some issue and was inserting CRLF chars. So I sent
