[OpenWrt-Devel] [PATCH] hostapd: enable PMKSA and OK caching for WPA3-Personal

[David Bauer]

This enables PMKSA and opportunistic key caching by default for
WPA2/WPA3-Personal, WPA3-Personal and OWE auth types.
Otherwise, Apple devices won't connect to the WPA3 network.

This should not degrade security, as there's no external authentication
provider.

Tested with OCEDO Koala and iPhone 7 (iOS 13.1).
