The Industry standard for jumbo frame MTU is 9216 bytes. When using DSA sub-system, an extra 4 byte tag is added to each frame. To allow users to set the standard 9216-byte MTU via ifconfig,increase AIROHA_MAX_MTU to 9220 bytes (9216+4).
What does the hardware actually support? Is 9220 the real limit? 10K? 16K? Andrew
