RA6M2 FreeRTOS+TCP large UDP messages.

FSP: 4.3


Module: FreeRTOS+TCP


IDE: VS Code

I have set up UDP comms and this works on its own. I can send and receive messages that are smaller than ~1.5kB. However, larger messages do not trigger FreeRTOS_recvfrom, or the lower layers as far as I've been able to dig. I've tried upping the size of g_ether0_ether_buffer0-7 and increasing ether_buffer_size to match but that doesn't seem to help. I also tried increasing ipconfigUDP_MAX_RX_PACKETS incase the packet was being split somewhere, this doesn't help either. Please help in increasing the max receivable message size.
