Subject: [PATCH] app/testpmd: fix Tx/Rx descriptor query error log

From: Hongbo Zheng <redacted>

Currently in testpmd, if we input "show port 0 rxq 0 desc 9999 status"
and if rte_eth_rx_descriptor_status return a negative value, testpmd will print
returns
"Invalid queueid = 0", seems user input an invalid queueid, while the actual
Users input/ user inputs
situation may be that 9999 is out of bounds, current information is misleading to
users.

This patch modify the Tx/Rx descriptor query error information in testpmd by
modifies
add offset information, now if we fail to query Tx/Rx descriptor, testpmd will
adding
print "Invalid queueid = 0, offset = 9999", then we can check our input.
The commit log has grammar mistakes. And I think you can simply explain what the patch does like:
This patch adds more err info for Tx/Rx descriptor query command.

And the print should be "Invalid input: queue id = 0, desc id = 9999" because you still don't tell users if it's queue id err or desc id err.
