1) netif->mtu = XEMACPS_MTU - XEMACPS_HDR_SIZE;#define XEMACPS_MTU 1500U /* max MTU size of Ethernet frame */
#define XEMACPS_HDR_SIZE 14U /* size of Ethernet header */ 2) how can I check exact length of pbufs? 3) Yep, IP_FRAG_USES_STATIC_BUF and LWIP_NETIF_TX_SINGLE_PBUF are both 0. Thanks! On 6.3.2017 10:51, Simon Goldschmidt wrote:

Could you give us more info: - what is netif->mtu set to - exact length of pbufs in a chaing > 1480 - setting of IP_FRAG_USES_STATIC_BUF and LWIP_NETIF_TX_SINGLE_PBUF (I assume both are 0 - default) That way I could try to have a quick look.
