Hi,
As far as I understand (maybe not) DHCP is not related to netif. DHCP is a
protocol you choose to use or not to use.
You need to control it from your own software. Meaning you decide if you want
to assign a static IP or get one via DHCP
Maybe I did not understand your question ?
BR,
Noam.

Subject: [lwip-users] Detect DHCP enabled for netif
Hello,
can I detect that the DHCP was enabled for a particular netif interface without
checking netif internals? I would like to know it only from netif, not from
some global flag or state variable associated with netif.
In case the system cannot change way of getting ip (static/dynamic) during
runtime, I could test the netif.dhcp for NULL but it means I have to know the
netif internals.
I could not find any function e.g.
dhcp_enabled_on_this_interface(netif) ... There is u8_t
dhcp_supplied_address(struct netif *netif) but the reason why the IP was not
supplied is missing.
I am using the latest master version from git.
Best
Martin
