Support of 802.1x (WPA2-Enterprise using EAP or PEAP) #254

Hello, currently, esp-link only offers connections to "Open" (unsecured) or Password-protected (PSK) WLANs. To use it in more secure environments like enterprise Wifi's, it would need have 802.1x support also.

WPA2-Enterprise support is there since SDK 1.5 (see this releasenote), so it should be possible.

I can't use this in my environment. I have some ESP8266 modules on the lan using EAP-PEAP with MSCHAPv2, so it is indeed possible and should be a minor change to add support.

I have had a go at hacking this into the EAP 2.1 branch, the issue is there is too much memory overhead by esp-link. EAP requires 26KiB of RAM, not including the space that would be required if one were to provide the root CA for certificate verification.

I'm afraid that as you describe EAP is not realistic unless the memory usage is somehow drastically slimmed down.
