[U-Boot-Users] PingSend

[richard at uclinux.net]

Strange...

Changing from:

int PingSend(void)
{
    static uchar mac[6];
    volatile IP_t *ip;
    volatile ushort *s;
    uchar *pkt;


to:

int PingSend(void)
{
    static uchar mac[6];
    IP_t *ip;
    ushort *s;
    uchar *pkt;


Solved the ping problem (o;
