Re: [PATCH v2] net: ena: Do not waste napi skb cache

Hello:

This patch was applied to netdev/net-next.git (master)
by Jakub Kicinski [off-list ref]:

By profiling, discovered that ena device driver allocates skb by
build_skb() and frees by napi_skb_cache_put(). Because the driver
does not use napi skb cache in allocation path, napi skb cache is
periodically filled and flushed. This is waste of napi skb cache.

As ena_alloc_skb() is called only in napi, Use napi_build_skb()
and napi_alloc_skb() when allocating skb.
