Subject: [dpdk-stable] [PATCH v5 0/2] app/testpmd: fix invalid rxq and txq nubmer settings
Date: Fri, 12 Jan 2018 16:10:01 +0800	[thread overview]
Message-ID: <1515744603-60457-1-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1515646700-56892-1-git-send-email-wei.dai@intel.com>

If an invlaid number of RX or TX queues is configured from testpmd
command like "port config all rxq number" or "port config all txq number".
or from --rxq and --txq in the command to start testpmd. The global variable
nb_rxq or nb_txq is updated by the invalid input.
This can cause testpmd crash. For example, if the maximum number of
RX or TX queues is 4, testpmd will crash after running commands
"port config all rxq 5", "port config all txq 5" and "start" in sequence.

With these 2 patches, if an invalid input is detected, it is refused and
testpmd keeps last correct values of  nb_rxq and nb_txq.

Fixes: ce8d561418d4 ("app/testpmd: add port configuration settings")
