++ * New interrupt handler strategy:
++ *
++ * An old interrupt handler worked using the traditional method of
++ * replacing an skbuff with a new one when a packet arrives. 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.
