Alexander Duyck fd11a83dd3 net: Pull out core bits of __netdev_alloc_skb and add __napi_alloc_skb ... This change pulls the core functionality out of __netdev_alloc_skb and places them in a new function named __alloc_rx_skb. The reason for doing this is to make these bits accessible to a new function __napi_alloc_skb. In addition __alloc_rx_skb now has a new flags value that is used to determine which page frag pool to allocate from. If the SKB_ALLOC_NAPI flag is set then the NAPI pool is used. The advantage of this is that we do not have to use local_irq_save/restore when accessing the NAPI pool from NAPI context. In my test setup I saw at least 11ns of savings using the napi_alloc_skb function versus the netdev_alloc_skb function, most of this being due to the fact that we didn't have to call local_irq_save/restore. The main use case for napi_alloc_skb would be for things such as copybreak or page fragment based receive paths where an skb is allocated after the data has been received instead of before.
