Preallocated skb's?

[Jeff Garzik <jgarzik@xxxxxxxxxxxxxxxx>]

Does anyone think that allocating skbs during system idle time would be
useful?

Net drivers (well, ethernet at least) often wind up allocating
maximum-sized skb's for use in Rx descriptors.  It seems to me that it
would be useful at interrupt time to have an skb already allocated,
falling back on current dev_alloc_skb behavior during times of system
load.
