Hi,
I wanted to know what is the significance of skb->mac.raw ?
Heres a code fragment from net/core/dev.c that i am trying to understand:
942 /*
943 * Bump the pointer to the next structure.
944 *
945 * On entry to the protocol layer. skb->data and
946 * skb->nh.raw point to the MAC and encapsulated data
947 */
948
949 /* XXX until we figure out every place to modify.. */
950 skb->h.raw = skb->nh.raw = skb->data;
951
952 if (skb->mac.raw < skb->head || skb->mac.raw > skb->data) {
953 printk(KERN_CRIT "%s: wrong mac.raw ptr, proto=%04x\n", skb->dev->name, skb->protocol);
954 kfree_skb(skb);
955 continue;
956 }
The kernel is 2.2.18.
Regards,
Amit
