Test Setup
Steps to reproduce
List the steps to reproduce the issue.
1.build dpdk
# CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=static
x86_64-native-bsdapp-gcc
# ninja -C x86_64-native-bsdapp-gcc
2.lanch app
# x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71
-n 4 -a 0000:af:00.0 -a 0000:af:00.1 --file-prefix=dpdk_875252_20211027094057 –
-i
3.execute dpdk command
# port stop all
# create bonded device 1 1
# add bonding slave 0 2
# create bonded device 1 1
# add bonding slave 1 3
# create bonded device 1 1
# add bonding slave 2 4
# add bonding slave 3 4
# set portlist 0,1,2,3,4
# port start 4
Show the output from the previous commands:
# testpmd>port start 4
Configuring Port 4 (socket 1)
Device with port_id=2 already stopped
Port 2 must be configured before MTU set
slave_configure(1741) - rte_eth_dev_set_mtu: port 2, err (-22)
bond_ethdev_start(1994) - bonded port (4) failed to reconfigure slave device
(2)
Fail to start port 4: Operation not permitted
Please stop the ports first
Done

ethdev: forbid MTU set before device configure
rte_eth_dev_configure() always sets MTU to either dev_conf.rxmode.mtu
or RTE_ETHER_MTU if application doesn't provide the value.
So, there is no point to allow rte_eth_dev_set_mtu() before since
set value will be overwritten on configure anyway.
