Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org, Changli Gao <xiaosuo@...il.com> Subject: [PATCH] net: use skb_get_rxhash() Although it is rare the line contains skb->rxhash is executed: * The forwarded skbs should have the the rx queue recoreded. * The local generated skbs should have non zero sk_hash in most of cases. when it is executed, a non zero rxhash will be better.
