-/*
- * 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.
