The first addresses a problem that could occur if the driver is not able to DMA map a fragment of the SKB. This would be a highly unusual event but it would leave the hardware descriptors in an invalid state which should be prevented. The second is a hazard that could occur if the driver is able to reclaim the first control block of a fragmented SKB before all of its fragments have completed processing by the hardware. In this case the SKB could be freed leading to reuse of memory that is still in use by hardware. ==================== Signed-off-by: David S. Miller --- 533da29b584de5ae0e9dafafbe52809f59cb5300
