DP83822IF: Jumbo packet support

g.f.

Part Number: DP83822IF

Hi,

I have a question about DP83822IF.

Is DP83822IF supporting Jumbo packet in MII mode?
If yes, what is supported maximum jumbo packet size in MII mode?
And are there any configuration of DP83822IF need to be done to use the feature?

best regards,
g.f.

Hi,

DP83822 does not support jumbo frame. You may want to use DP83848.

Hi Geet,

Thank you for the reply.
Do you mean that DP83822 doesn't support jumbo frame only in MII mode?
In DP83822 datasheet page.32 "Table.4 Recommended RMII Packet Sizes", it seems that DP83822 supporting 16800bytes(+/-50ppm).

I have one more question.
Does DP83848 support jumbo frame in MII mode?

Hi,

It is tested for RMII only on DP83822. We expect to work by design but not validated.

For DP83848, please refer to below thread
