Hi Mohammed, the crash is happening in DPDK when trying to get link status.
> Also tested with v19.08.2 and v18.10
I suppose it means the trace below uses master?
Also, could you try again building DPDK in debug mode (note: you'll need to
remove any vpp-ext-deps package 1st)?
~# make rebuild DPDK_DEBUG=y
