DHCPV4 and CONFIG_NET_SOCKETS_SOCKOPT_TLS

Hi,

using zephyr-v2.1.0

I have build the mqtt_publisher sample application for the stm32f746g_disco and it works fine.

I have build the dhcpv4_client sample application for the stm32f746g_disco and it works fine.

When I want to combine both, mqtts and dhcpv4, the dhcpv4 is always timing out.

I have tried step by step.

Using dhcpv4_client sample:

add to prj.conf

# Enable Sockets support
CONFIG_NET_SOCKETS=y
CONFIG_NET_SOCKETS_SOCKOPT_TLS=y

Then the application is no longer compiling:

zephyr/subsys/net/lib/sockets/sockets_tls.c:1735:45: error: 'struct tls_context' has no member named 'ssl'

Does sock_opt_tls is depending on mbedtls? In the guiconfig there is no dependency mentioned between CONFIG_NET_SOCKETS_SOCKOPT_TLS and CONFIG_MBEDTLS.
The sockets_tls uses different mbedtls defines.

What is the correct solution for this problem?

kr,

Wim
