Re: [PATCH net 1/1] net: stmmac: disable Split Header (SPH) for Intel platforms

Hi,

Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation of Split Header (SPH) feature is not supported for Ipv4 fragmented packet. This SPH limitation will cause ping failure when the packets size exceed the MTU size. For example, the issue happens once the basic ping packet size is larger than the configured MTU size and the data is lost inside the fragmented packet, replaced by zeros/corrupted values, and leads to ping fail.

So, disable the Split Header for Intel platforms.

Does this issue only apply on Intel platforms?

Thanks, Kurt
