[BUG] lMulticastRequest has incomplete type

[QuentinCaldeira-eaton]

Reproduction steps

For a personal application, I try to develop an STM32 application on Zephyr OS. I've made some modification to the Zephyr platform, as discussed here #33471 (comment).
My issue is : when I use west tools to build my app, I've some issues with UDP :

../../../../connectedhomeip/src/inet/UDPEndPointImplSockets.cpp: In member function 'virtual CHIP_ERROR chip::Inet::UDPEndPointImplSockets::IPv4JoinLeaveMulticastGroupImpl(chip::Inet::InterfaceId, const chip::Inet::IPAddress&, bool)':
../../../../connectedhomeip/src/inet/UDPEndPointImplSockets.cpp:788:20: error: aggregate 'chip::Inet::UDPEndPointImplSockets::IPv4JoinLeaveMulticastGroupImpl(chip::Inet::InterfaceId, const chip::Inet::IPAddress&, bool)::ip_mreq lMulticastRequest' has incomplete type and cannot be defined
  788 |     struct ip_mreq lMulticastRequest;
      |                    ^~~~~~~~~~~~~~~~~

I can't resolve this error and I don't understand why this appears. Did I miss something ?

I think it's because Zephyr socket.h doesn't implement struct ip_mreq but ip_mreqn
