Hi,
I'm looking at definition of xdp_md:
struct xdp_md {
__u32 data;
__u32 data_end;
};
I'm curious why are we using __u32? Isn't data and data_end an 8-byte
pointer to the packet's buffer? For example in xdp2_kern.c
int xdp_prog1(struct xdp_md *ctx)
{
void *data_end = (void *)(long)ctx->data_end;
void *data = (void *)(long)ctx->data;
struct ethhdr *eth = data;
Am I missing something? Thank you!
Regards,
William
