-+ * 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.
