Subject: RE: can we reuse an skb

I am also thinking about this...

i.e.pcnet32.c
seems the skb will be claimed to be unuseful(mark some bits) in the device driver, than it will be recycled in the softirq handler,

that means unable to reuse it, unless modidy the driver.

Hi,

For an ethernet driver, we need to allocate some pool of SKBs for receiving packets. Is there any way we can reuse the same SKBs without the need to re-allocate in atomic every time one has been used up for netif_rx(). 

Any pointers will be helpful.
