Re: [lwip-users] Program hangs in ip_frag()

[pekez]

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!
