MTU VintageNetQMI with SIM700G - is there any way for QMI or Kernel to automatically detect the MTU and adjust?

Hey folks! I am using vintage_net_qmi for LTE connectivity using the SIM700G, with local SIMs it works perfectly, but when using a SIM with roaming it doesn’t, and the problem is that when a SIM is roaming the MTU drops to 1400, so I have to manually set the MTU to the interface, is there any way for QMI or Kernel to automatically detect the MTU and adjust it?

I solved it by getting the network MTU using the WDS Get Current Settings request.

The solution is in the active branches.
