[dpdk-dev] [PATCH] app/testpmd: add cmdline option to set Rx mq mode

[dpdk-dev] [PATCH] app/testpmd: add cmdline option to set Rx mq mode

[Xiaoyu Min]

One new cmdline option `--rx-mq-mode` is added in order to have the
possibility to check whether PMD handle the mq mode correctly or not.

The reason is some NICs need to do different settings based on different
RX mq mode, i.e RSS or not.

With this support in testpmd, the above scenario can be tested easily.

[dpdk-dev] [PATCH v2] app/testpmd: add cmdline option to set Rx mq mode

[Xiaoyu Min]

One new cmdline option `--rx-mq-mode` is added in order to have the
possibility to check whether PMD handle the mq mode correctly or not.

The reason is some NICs need to do different settings based on different
RX mq mode, i.e RSS or not.

With this support in testpmd, the above scenario can be tested easily.

Do you think does it worth to say the bitmask is for modes that can be enabled,
to remove need to look the code, not sure.

This is not the "RX mq mode value", the above help string seems more accurate,

The variable name gives as much context as the comment, may it be dropped?

It is good to expand the 'mq' at least in the documentation, and I guess it is
"multi queue".

So you mean something like:
+	printf("  --rx-mq-mode=0xX: hexadecimal bitmask of RX mq mode can be enabled\n");

Yes, we need this cast otherwise the coverity will complain about enum type

Here all variables looks an enum, 'mq_mode' type is enum, 'rx_mq_mode' is enum
and 'ETH_MQ_RX_RSS' is enum item. With which type it is mixed with?

I didn't run coverity for it, if it is giving warning OK to keep them, but can
you please double check with coverity scan?

As you asked, I double checked with coverity by removing the enum cast. The coverity
has the below warning [1] but this time the warning is supressed by filter(I guess
it's newly added). It seems coverity doesn't allow the bitwise operators(?)
Anyhow I prefer to keep the cast this time since it's already there.

[dpdk-dev] [PATCH v3] app/testpmd: add cmdline option to set Rx mq mode

[Xiaoyu Min]

One new cmdline option `--rx-mq-mode` is added in order to have the
possibility to check whether PMD handle the mq mode correctly or not.

The reason is some NICs need to do different settings based on different
RX mq mode, i.e RSS or not.

With this support in testpmd, the above scenario can be tested easily.
