Hi.
Could somebody explain me this comment?:
/*
* Incoming packets are placed on per-cpu queues so
that
* no locking is needed.
*/
struct softnet_data
{
int throttle;
int cng_level;
int avg_blog;
struct sk_buff_head input_pkt_queue;
struct net_device *output_queue;
struct sk_buff *completion_queue;
} __attribute__((__aligned__(SMP_CACHE_BYTES)));
I didn't understand why packets are placed so and why
locking isn't needed?
