Thanks for all the comments, please check my v7 which follow your suggestion.

My almost classic comment for testpmd:
Do we need a new high level command "queue setup" for this. Can't we extend
existing port/queue setting commands for the sake of the usability. Each feature
is trying to add its new command in its new syntax what suits to author.

And why both (ring_size) and (offloads) set in same command, as far as I can see
you can't ignore them, so to set ring_size I should know offloads for queue too,
they don't look too related why setting together in same command.

Isn't there any other command to set ring_size? I would be surprised if there is
no. And there are a few new command for setting/getting offloads. Can't we
re-use them?


[dpdk-dev] [PATCH v6 2/3] app/testpmd: add command for queue setup

2018-04-07 Thread Qi Zhang
Add new command to setup queue:
queue setup (rx|tx) (port_id) (queue_idx) (ring_size) (offloads)

rte_eth_[rx|tx]_queue_setup will be called corresponsively

Signed-off-by: Qi Zhang 
Acked-by: Konstantin Ananyev 
---
v6:
- fix error message for rx_free_thresh check.

v5:
- fix command description.

v4:
- fix missing offload in command line.

v3:
- add offload parameter to queue setup command.
- couple code refactory.
