[dpdk-dev] [PATCH v2] app/testpmd: fix to add offloads confguration for queue

[Wei Zhao <wei.zhao1@intel.com>]

When adding offloads from commandline, not only port
related configuration bits should be set, but also queue
related offloads configuration bits, or it will cause error.
For example, test in this process for ixgbe:
(1)./x86_64-native-linuxapp-gcc/app/testpmd -c 0x6 -n 4
-- -i --portmask=0x1 --port-topology=loop --disable-crc-strip
(2)port stop all
(3)port config all crc-strip on
(4)port start all
we will see "Fail to configure port 0 rx queues" of warning info.

Fixes: 0074d02fca21 ("app/testpmd: convert to new Rx offloads API")
