Hi Wei,

There is a build error applied your patches to the latest DPDK version.
/root/dpdk/app/test-pmd/testpmd.c: In function 'check_nb_rxq':
/root/dpdk/app/test-pmd/testpmd.c:579:3: error: 'pid' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   printf("Fail: input rxq (%u) can't be greater "
   ^
/root/dpdk/app/test-pmd/testpmd.c: In function 'check_nb_txq':
/root/dpdk/app/test-pmd/testpmd.c:625:3: error: 'pid' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   printf("Fail: input txq (%u) can't be greater "
   ^
My gcc verison is gcc version 5.3.1 20151207 (Red Hat 5.3.1-2) (GCC)

Could you help to check it?

Thanks.
Yuan.

Subject: [PATCH v4 0/2] app/testpmd: fix invalid rxq and txq nubmer settings

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")

v3: follow the guide from Konstantin to use functions to check
    input rxq and txq instead of usage of new added global variables.

v2: fix a bug in v1
