Is mtcp over DPDK compatible with Linux Kernel 5.9? I got some errors at dpdk-iface.h #310

I am using DPDK latest stable version 19.11.5, and while I run last step (62) of ./setup_mtcp_dpdk_env.sh which is about Are you using Intel NIC? y I got the following error:

make -C /lib/modules/5.9.0-050900rc6-generic/build/ M=/home/kleir/Desktop/Lib_userkernel_code/mtcp/dpdk-iface-kmod modules

As, it can be seen from my error, I am using Kernel version 5.9. I guess the problem is that maybe dpdk_iface is not patched for latest Linux Kernel, but I may be wrong. Can you provide me any workaround about such problem?

See #305 and #306. In short, mTCP is shit.
