disable udp checksum for zynq lwip

hi all,

 

I'm using zynq with raw LwIP stack.

Now I must receive many UDP packets, in which some packets are composed with wrong udp checksum field. Since I can't change the sender's behavior, I will try to disable the checksum validation in receiver.

 

I noticed that the checksum offloading is carried out in GEM and can't be disabled, but in the BSP settings dialog, as in the following picture,

temac.pngwhy there are tcp related offloading options? And no udp related offloading options?

Is it possible to receive those wrong UDP packets? how?

 

best regards
