However, it only applies if host networking is NOT used. This change applies the same for containers where host networking is employed.

The full CA chain is necessary for validating the incoming server certificate when it is signed by an intermediate CA and the intermediate CA cert is not included in the EAP-TLS ServerHello. In this scenario, wpa_supplicant needs to have both the intermediate CA and the root CA in its `ca_file`. Similarly, the full client certificate chain is needed when the ISP expects/requires that the client (wpa_supplicant) sends the client cert + the intermediate CA (or even + the root CA) as part of the EAP-TLS ClientHello.
