H A Dskbuff.rst15 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
27 dataref and headerless skbs

H A Dnetdev-features.rst129 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 Dxdp-rx-metadata.rst79 ``skbs``. However, TC-BPF programs can access the XDP metadata area using
83 can override some of the metadata used for building ``skbs``.
H A Dsegmentation-offloads.rst60 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.
181 will check for GSO_BY_FRAGS and WARN if asked to manipulate these skbs.
