  "message": "[TCP]: Simplify SKB data portion allocation with NETIF_F_SG.\n\nThe ideal and most optimal layout for an SKB when doing\nscatter-gather is to put all the headers at skb-\u003edata, and\nall the user data in the page array.\n\nThis makes SKB splitting and combining extremely simple,\nespecially before a packet goes onto the wire the first\ntime.\n\nSo, when sk_stream_alloc_pskb() is given a zero size, make\nsure there is no skb_tailroom().  This is achieved by applying\nSKB_DATA_ALIGN() to the header length used here.\n\nNext, make select_size() in TCP output segmentation use a\nlength of zero when NETIF_F_SG is true on the outgoing\ninterface.\n\nSigned-off-by: David S. Miller \u003cdavem@davemloft.net\u003e\n",
