While reviewing this I noticed that the gro cells code goes through all of the trouble of allocating full per-cpu objects to manage the packet queuing and processing, but then it uses a full spinlock for protection. It ought to be sufficient to just block out BH processing or, at worst, local cpu interrupts, to protect the individual per-cpu cells. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
