void s2io_tasklet (unsigned long dev_addr);
This is the tasklet or the bottom half of the ISR. This is an extension of the ISR which is scheduled by the scheduler to be run when the load on the CPU is low. All low priority tasks of the ISR can be pushed into the tasklet. For now the tasklet is used only to replenish the Rx buffers in the Rx buffer descriptors.
void.
