From: Hongbo Zheng zhenghongbo3@huawei.com
In testpmd, when we input "show config rxtx", we can see like this:
1: testpmd> show config rxtx 2: io packet forwarding packets/burst=32 3: nb forwarding cores=1 - nb forwarding ports=1 4: port 0: RX queue number: 1 Tx queue number: 1 5: Rx offloads=0x0 Tx offloads=0x10000 6: RX queue: 0 7: RX desc=1024 - RX free threshold=32 8: RX threshold registers: pthresh=0 hthresh=0 wthresh=0 9: RX Offloads=0x0 10: TX queue: 0 11: TX desc=1024 - TX free threshold=928 12: TX threshold registers: pthresh=0 hthresh=0 wthresh=0 13: TX offloads=0x10000 - TX RS bit threshold=32
We can see RX/Rx/TX/Tx is mixed used. Also in other places in testpmd, RX/Rx/TX/Tx is mixed used.
This patch fix the mixed use of RX/Rx/TX/Tx in testpmd by change to unified use Rx/Tx.
The commit log is too redundant. The following is enough to explain what this
patch does:
RX/TX and Rx/Tx are mixed used in testpmd print and comments. This patch
unifies them as Rx/Tx.
Except this, the patch looks good to me.
But one big concern, this patch will break all of the CI tests because the DTS
scripts check if the results are the same as expected and this patch change a lot of the print.
So I think the DTS maintainer needs to be aware of this.
I think test dpdk-testpmd output is a part of API. Of course, it is not an API, but such cosmetic changes in output will be much more painful
than API changes.
Output parsers will simply stop to work. I think such changes should go through the deprecation process.
Of course, it would be useful to change comments and may be even error log messages right now, but not commands output.
+Lijuan DTS maintainer
It has big impact with CI system, most of test cases depended on the testpmd
output, if changed, our CI system will be broken, Is it really worth it ?
I think it's necessary to keep the style consistent and to constrain everyone to do so in the future.However, if the DTS changes greatly, I think it is possible to require the new print to be consistent and the historical part to remain unchanged.Because the uniform change is also Xiaoyun's suggestion, we think the opinion is reasonable, but we are not sure how much it will affect DTS.
I think we should drop this patch. But we'll keep consistent for future print when reviewing. What do you think?
+1 to have consistency on the new code, and as the old code changed by time. Instead of big syntax cleanup.
As well as output parsing problem, this also can cause trouble on backporting patches for stable trees because of conflicts it will create.
And please separate this patch with the other twos. Don't mix them in one
patchset. It's not for the same purpose.
