What exactly do you mean by an 8188 chip? There are RTL8188EE, RTL8188CE, and
RTL8188EU chips? You likely mean the last one, as the first two PCI chips have
mac80211 drivers.

If you want to use nl80211/cfg80211 commands with driver r8188eu, you will need
to add the necessary code for that driver to support that API. Modifying the
supplicant is probably not the way to go.

On my x86_64 system, the standard supplicant works with NetworkManager and r8188eu.
