jumbo frames with DM8148

Hello,

I am trying to configure dm8148 board to use jumbo frames, but I can't get ping working.

My configuration is:

1. DM8148 custom board

2. ethernet configuration:

3. in windows pc: I've changed adapter setting to 4K

4. in target: ifconfig eth0 mtu 1700

5. ping from windows: >ping 10.0.0.2 -f -l 1600

• Does DM8148 support jumbo frames ?
• Does the phy transiever need to support jumbo frames too (I didn;t see it mentioned in the datasheet) ?
  
  
  Thank you for any suggestion.
