Hi, check that you have set up all the skb fields (skb->nh.raw ?) before sending your packet, arp_send is a good example, something similar to : + /* + * Allocate a buffer + */ + + skb = alloc_skb(sizeof(struct adapt_pkt)+(dev->hard_header_len), GFP_ATO MIC); + if (skb == NULL) + return; + + + skb_reserve(skb, (dev->hard_header_len)); + skb->nh.raw = skb->data; + apkt = (struct adapt_pkt *) skb_put(skb,sizeof(struct adapt_pkt)); + skb->dev = dev; + skb->protocol = __constant_htons (ETH_P_ADAPT); + src_hw = dev->dev_addr; + dest_hw = dev_addr; + ptype = ETH_P_ADAPT; + if (dev->hard_header && dev->hard_header(skb,dev,ptype,dest_hw,src_hw,sk b->len) < 0) + goto out; On Tue, Jul 08, 2003 at 08:01:17PM +0800, blue wrote: > Hi, all: > I wrote a Linux Networking module, and tried send my own sk_buff out.
