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.
