Re: [lwip-users] Pbuf alloc size

[Kjel Snorre Jahrus]

Hey there,

My problem is not the actual 14 extra bytes that I am allocating but the fact that for each received package I am allocating mtu(1500) bytes, instead of the size of the received frame which might be 60 bytes for example.

Best regards,

Kjel Snorre

14 is the size of the ethernet header.  The MTU should include the ethernet header though.
