Re: [lwip-users] Size of ARP Response too much 1534 bytes, packet contains lots of 0xA5 values

FIXED, 

It was an issue with my code, in interface controller, I have to set the len and tot_len of pbuf buffer to the length I have read from driver. Thanks

Ishmeet,

As you stated, your ARP request is 64 bytes, which is OK. I guess it has been padded by your ethernet HW. But 2 things :

  - ARP reponse comes from the other end of the link, that is, it may not be padded (possibly).

  - ARP reponse is supposed to be 28 bytes : http://fr.wikipedia.org/wiki/Address_Resolution_Protocol

So if your reponse is 1534 bytes, i agree with Krzysztof, maybe you've got an issue with your stack...

ARP Response too much 1534 bytes(over than MTU 1500byte??) Does the IP reassembly and IP fragment turn on? Maybe you can capture the packets by wireshark.
