These drivers work bad with changing the MAC address.
See [1], [2], [3] for reports about failures with "wl" driver.
[3] also blacklists driver "8188eu". While we already blacklist "r8188eu",
it seems that some installations use the alternative name "8188eu" [4].
"wpasupplicant" package on Ubuntu 18.04 (bionic) provides the file
"/usr/lib/NetworkManager/conf.d/no-mac-addr-change.conf", which
blacklists the same drivers. See also bug [3] which added the file.
