We created a Network driver for our Fibre Channel NIC in Windows 10, using NDIS 6.20.
We were able to set MTU size to 32768 bytes. The setting was confirmed by using command "netsh interface ipv4 show interfaces". However, NDIS provided our driver with 1500 byte frames only, even we sent 32768 byte data in the socket application. Please help explaining the behavior. What can we do to allow NDIS to provide our driver with more than 1500 byte frames. If there is any limitation in NDIS, what is the maximum MTU size can we use?
Additional notes: If we set MTU size to 1500 or 1000 bytes, NDIS provided our driver with 1500 or 1000 byte frames as expected.
