+ * 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.
