Hi All, Is it possible to map a address like skb->data in to struct page. My requirement is to convert multiple skb to a single master skb, having all the data of other skb. i.e, i want add skb->data of multiple skb to a single skb as the fragments. So instead of making a memcpy every time, i just call skb_add_rx_frag my requirement is some thing like this *.* *.* *struct page *page = virt_to_page(skb->data);* * * *skb_add_rx_frag(master_skb, skb_shinfo(master_skb)->nr_frags, page, off, skb->len)* *.* *.* And can some one please tell what is the use of the functions like * virt_to_page* and *kmap_atomic_to_page*, i tried calling virt_to_page(skb->data), but when i print the data in the page address ( page_address(page) ) and the data in pointed by skb->data, i came to know its mapping to a wrong page. so can some one please explain me what is correct way to do this. Thanks in advance.
