According to this webpage: https://mininet-wifi.github.io/sixlowpan/ "6LoWPAN is supported by Mininet-WiFi thanks to the fakelb and mac802154_hwsim module. Both modules have been developed to support 6lowpan, but mac802154_hwsim (which is supported from Linux Kernel version 4.18) is gradually replacing fakelb." Since Centos 8 is on Kernel 4.18, maybe it's already native there. Doesn't help the chap with Centos 7 though. -- Can we uninstall 2020 and install it again? This one has a virus.
