> Testpmd tries to calculate mbuf size based on "max Rx packet size" and
> "max MTU segment number".
> When driver set a "nb_mtu_seg_max" to zero, it causes division by zero
> segmentation fault in testpmd.
> If the PMD set "nb_mtu_seg_max" to zero, testpmd shouldn't try to
> calculate the mbuf size.
> Fixes: 33f9630fc23d ("app/testpmd: create mbuf based on max supported segments")
