dev_queue_xmit_nit() clones the skb for each tap, so the reference count on the original skb remains 1. Ben. -- Ben Hutchings, Staff Engineer, Solarflare Not speaking for my employer; that's the marketing department's job. They asked us to note that Solarflare product names are tradema...

May be stored at 4 degree C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degree C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. ...

alloc_skb or dev_alloc_skb 当协议栈需要TX Packet 时,会调用 alloc_skb 分配skb实体;而设备驱动程序在RX Packet时,会调用 dev_alloc_skb 来分配skb,当然这是一种低效的方式,因为需要将RX的数据 memcpy 到 skb 指向的 buffer 中。下面以 dev_alloc_skb 为例,说明该函数执行后的内存空间状态。dev...
