CentOS Linux release 7.8.2003 (Core) error: unknown field ‘ndo_change_mtu’ specified in initializer

[vincentmli]

I am running mTCP on CentOS 7.8.2003 release kernel 3.10.0-1127.el7.x86_64, installed kernel devel package that is required by building igb_uio

ls -l /lib/modules/3.10.0-1127.el7.x86_64/
total 3296
lrwxrwxrwx   1 root root     44 Aug  4 20:05 build -> /usr/src/kernels/3.10.0-1127.18.2.el7.x86_64

got errors when building dpdk_iface.o
