hostapd: Activate Simultaneous Authentication of Equals (SAE)
This build the full openssl and wolfssl versions with SAE support which is the main part of WPA3 PSK. This needs elliptic curve cryptography which is only provided by these two external cryptographic libraries and not by the internal implementation. The WPA3_Specification_v1.0.pdf file says that in SAE only mode Protected Management Frames (PMF) is required, in mixed mode with WPA2-PSK PMF should be required for clients using SAE, and optional for clients using WPA2-PSK. The defaults are set now accordingly. This increases the ipkg size by 8.515 Bytes. Old: 394.026 Bytes New: 402.541 Bytes Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
