However ++ * the rx rings do not need to contain a static number of buffer ++ * descriptors, thus it makes sense to move the memory allocation out ++ * of the main interrupt handler and do it in a bottom half handler ++ * and only allocate new buffers when the number of buffers in the ++ * ring is below a certain threshold. In order to avoid starving the ++ * NIC under heavy load it is however necessary to force allocation ++ * when hitting a minimum threshold. The strategy for alloction is as ++ * follows: ++ * ++ * RX_LOW_BUF_THRES - allocate buffers in the bottom half ++ * RX_PANIC_LOW_THRES - we are very low on buffers, allocate ++ * the buffers in the interrupt handler ++ * RX_RING_THRES - maximum number of buffers in the rx ring ++ * ++ * One advantagous side effect of this allocation approach is that the ++ * entire rx processing can be done without holding any spin lock ++ * since the rx rings and registers are totally independent of the tx ++ * ring and its registers. This of course includes the kmalloc's of ++ * new skb's. Thus start_xmit can run in parallel with rx processing ++ * and the memory allocation on SMP systems. ++ * ++ * Note that running the skb reallocation in a bottom half opens up ++ * another can of races which needs to be handled properly. In ++ * particular it can happen that the interrupt handler tries to run ++ * the reallocation while the bottom half is either running on another ++ * CPU or was interrupted on the same CPU. To get around this the ++ * driver uses bitops to prevent the reallocation routines from being ++ * reentered. ++ * ++ * TX handling can also be done without holding any spin lock, wheee ++ * this is fun! since tx_csm is only written to by the interrupt ++ * handler. ++ */ ++ ++/* ++ * Threshold values for RX buffer allocation - the low water marks for ++ * when to start refilling the rings are set to 75% of the ring ++ * sizes. It seems to make sense to refill the rings entirely from the ++ * intrrupt handler once it gets below the panic threshold, that way ++ * we don't risk that the refilling is moved to another CPU when the ++ * one running the interrupt handler just got the slab code hot in its ++ * cache. ++ */ ++#define RX_RING_SIZE AR2313_DESCR_ENTRIES ++#define RX_PANIC_THRES (RX_RING_SIZE/4) ++#define RX_LOW_THRES ((3*RX_RING_SIZE)/4) ++#define CRC_LEN 4 ++#define RX_OFFSET 2 ++ ++#define AR2313_BUFSIZE (AR2313_MTU + ETH_HLEN + CRC_LEN + RX_OFFSET) ++ ++#ifdef MODULE ++MODULE_AUTHOR("Sameer Dekate<sdekate@arubanetworks.com>");
