The maximum size of jumbo frame is 10kByte.
Does all DP83867 device support jumbo frame up to 13.5kByte? It seems the thread below mentions it, but I am not sure.
All versions of DP83867 can support 10kByte jumbo frames.
The maximum frame size supported is directly proportional to clock frequency offset between the two link partners.
If you can minimize the offset of clocks to +/-50ppm, then DP83867 can support 10kByte by default.
If the clock offset is +/-100ppm, then we need to program a few registers to get 10kByte jumbo frame transmission working.
