| H A D | skbuff.rst | 15 Shared skbs and skb clones
19 to keep a struct sk_buff alive. skbs with a ``sk_buff.users != 1`` are referred
20 to as shared skbs (see skb_shared()).
22 skb_clone() allows for fast duplication of skbs. None of the data buffers
24 &skb_shared_info.refcount indicates the number of skbs pointing at the same

| H A D | netdev-features.rst | 129 ndo_start_xmit can handle skbs with frags in high memory.
133 Those features say that ndo_start_xmit can handle fragmented skbs:
134 NETIF_F_SG --- paged skbs (skb_shinfo()->frags), NETIF_F_FRAGLIST ---
135 chained skbs (skb->next/prev list).

| H A D | segmentation-offloads.rst | 60 UFO is deprecated: modern kernels will no longer generate UFO skbs, but can
165 padded and stored as chained skbs, and skb_segment() splits based on those.
