194 II. Board-specific settings
200 The Starfire hardware uses multiple fixed-size descriptor queues/rings. The
207 utilize the hardware two-level priority queue. When modifying the
208 RX/TX_RING_SIZE pay close attention to page sizes and the ring-empty warning
218 minimum-length padding. It does not use the completion queue
219 consumer index, but instead checks for non-zero status entries.
224 queue consumer index, but instead checks for non-zero status entries.
237 skbuff at an offset of "+2", thus 16-byte aligning the IP header.
241 The driver runs as two independent, single-threaded flows of control. One
242 is the send-packet routine, which enforces single-threaded use by the
243 dev->tbusy flag. The other thread is the interrupt handler, which is single

266 - StopOnPerr is broken, don't enable
267 - Hardware ethernet padding exposes random data, perform software padding
268 instead (unverified -- works correctly for all the hardware I have)
296 Unlike software-only systems, device drivers interact with complex hardware.
