Hello lkml, jeff and donald,
I have been testing the D-Link DFE-580TX Quad channel server card (4
port nic), on kernel 2.4.18 with little success.
Attached are the appropriate results of dmesg, ifconfig, lspci and
modules.conf; aswell as the results of the pci-testing tool found on
scyld.com, however the card does not support mii testing, claiming to
have no MII transceiver.
Specifically, the sundance module can be modprobe'd, and the interfaces
of the 4port nic (eth2->eth5) can be brought up with ifconfig, and to
all intents and purposes *should* be working, however the results of
`tail dmesg` and `tail messages` show a transmit timeout on all the
nic's interfaces and testing the interfaces with ping returns host
unreachable (only on this card, the onboard nic and single port pci card
both work properly).
I would appreciate being informed if there is a fix in a later
version,or if any more debugging information is required I would be
happy to oblige.
Matthew Hall

Yes and no, This version didn't work (once I back-ported it to compile on 2.4.18, which I suppose I may have not been designed to do), but I had already got v1.02 to compile and work properly with no problems (on a previous post). On a similar note, but not related to the original, has anyone used this driver on 20 ports? I'll be looking into using the driver with 4/5 of the dfe-580's and was wondering about scalability...?

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.
