The network stack uses two separate caches per CPU to handle fragment

allocation. The netdev_alloc_cache is used by callers making use of the

__netdev_alloc_frag and __netdev_alloc_skb calls. The napi_alloc_cache is

netdev_alloc_frag and __netdev_alloc_skb calls. The napi_alloc_cache is

used by callers of the __napi_alloc_frag and __napi_alloc_skb calls. The

main difference between these two calls is the context in which they may be

called. The "netdev" prefixed functions are usable in any context as these
