Board Compatibility + +This driver is designed for the Sundance Technologies "Alta" ST201 chip. + +II. Board-specific settings + +III. Driver operation + +IIIa. Ring buffers + +This driver uses two statically allocated fixed-size descriptor lists +formed into rings by a branch from the final descriptor to the beginning of +the list. The ring sizes are set at compile time by RX/TX_RING_SIZE. +Some chips explicitly use only 2^N sized rings, while others use a +'next descriptor' pointer that the driver forms into rings. + +IIIb/c. Transmit/Receive Structure + +This driver uses a zero-copy receive and transmit scheme. +The driver allocates full frame size skbuffs for the Rx ring buffers at +open() time and passes the skb->data field to the chip as receive data +buffers. When an incoming frame is less than RX_COPYBREAK bytes long, +a fresh skbuff is allocated and the frame is copied to the new skbuff. +When the incoming frame is larger, the skbuff is passed directly up the +protocol stack. Buffers consumed this way are replaced by newly allocated +skbuffs in a later phase of receives. + +The RX_COPYBREAK value is chosen to trade-off the memory wasted by +using a full-sized skbuff for small frames vs. the copying costs of larger +frames. New boards are typically used in generously configured machines +and the underfilled buffers have negligible impact compared to the benefit of +a single allocation size, so the default value of zero results in never +copying packets. When copying is done, the cost is usually mitigated by using +a combined copy/checksum routine. Copying also preloads the cache, which is +most useful with small frames. + +A subtle aspect of the operation is that the IP header at offset 14 in an +ethernet frame isn't longword aligned for further processing. +Unaligned buffers are permitted by the Sundance hardware, so +frames are received into the skbuff at an offset of "+2", 16-byte aligning +the IP header. + +IIId. Synchronization + +The driver runs as two independent, single-threaded flows of control. One +is the send-packet routine, which enforces single-threaded use by the +dev->tbusy flag. The other thread is the interrupt handler, which is single +threaded by the hardware and interrupt handling software. + +The send packet thread has partial control over the Tx ring and 'dev->tbusy' +flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next +queue slot is empty, it clears the tbusy flag when finished otherwise it sets +the 'lp->tx_full' flag. + +The interrupt handler has exclusive control over the Rx ring and records stats +from the Tx ring. After reaping the stats, it marks the Tx queue entry as +empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it +clears both the tx_full and tbusy flags. + +IV. Notes + +IVb.
