[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1. Use the following command to build DPDK: 
CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=static
x86_64-native-linuxapp-gcc/ 
ninja -C x86_64-native-linuxapp-gcc/ 

2. Execute the following command in the dpdk directory.   

MALLOC_PERTURB_=219 DPDK_TEST=link_bonding_autotest
/root/dpdk/x86_64-native-linuxapp-gcc/app/test/dpdk-test -c 0xff

MALLOC_PERTURB_=219 DPDK_TEST=link_bonding_rssconf_autotest
/root/dpdk/x86_64-native-linuxapp-gcc/app/test/dpdk-test -c 0xff

MALLOC_PERTURB_=219 DPDK_TEST=link_bonding_mode4_autotest
/root/dpdk/x86_64-native-linuxapp-gcc/app/test/dpdk-test -c 0xff

Show the output from the previous commands.

   net/bonding: fix descriptor limit reporting



   Commit 5be3b40fea60 ("net/bonding: fix values of descriptor limits")
    breaks reporting of "nb_min" and "nb_align" values obtained from
    back-end devices' descriptor limits. This means that work done
    by eth_bond_slave_inherit_desc_lim_first() as well as
    eth_bond_slave_inherit_desc_lim_next() gets dismissed.



   Revert the offending commit and use proper workaround
    for the test case mentioned in the said commit.



   Meanwhile, the test case itself might be poorly constructed.
    It tries to run a bond with no back-end devices attached,
    but, according to [1] ("Requirements / Limitations"),
    at least one back-end device must be attached.
