/* * This driver currently supports Tigon I and Tigon II based cards * including the Alteon AceNIC, the 3Com 3C985[B] and NetGear * GA620. The driver should also work on the SGI, DEC and Farallon * versions of the card, however I have not been able to test that * myself. * * This card is really neat, it supports receive hardware checksumming * and jumbo frames (up to 9000 bytes) and does a lot of work in the * firmware. Also the programming interface is quite neat, except for * the parts dealing with the i2c eeprom on the card ;-) * * Using jumbo frames: * * To enable jumbo frames, simply specify an mtu between 1500 and 9000 * bytes to ifconfig. Jumbo frames can be enabled or disabled at any time * by running `ifconfig eth<X> mtu <MTU>' with <X> being the Ethernet * interface number and <MTU> being the MTU value. * * Module parameters: * * When compiled as a loadable module, the driver allows for a number * of module parameters to be specified. The driver supports the * following module parameters: * * trace=<val> - Firmware trace level. This requires special traced * firmware to replace the firmware supplied with * the driver - for debugging purposes only. * * link=<val> - Link state. Normally you want to use the default link * parameters set by the driver. This can be used to * override these in case your switch doesn't negotiate * the link properly. Valid values are: * 0x0001 - Force half duplex link. * 0x0002 - Do not negotiate line speed with the other end. * 0x0010 - 10Mbit/sec link. * 0x0020 - 100Mbit/sec link. * 0x0040 - 1000Mbit/sec link. * 0x0100 - Do not negotiate flow control. * 0x0200 - Enable RX flow control Y * 0x0400 - Enable TX flow control Y (Tigon II NICs only). * Default value is 0x0270, ie. enable link+flow * control negotiation. Negotiating the highest * possible link speed with RX flow control enabled. * * When disabling link speed negotiation, only one link * speed is allowed to be specified! * * tx_coal_tick=<val> - number of coalescing clock ticks (us) allowed * to wait for more packets to arive before * interrupting the host, from the time the first * packet arrives. * * rx_coal_tick=<val> - number of coalescing clock ticks (us) allowed * to wait for more packets to arive in the transmit ring, * before interrupting the host, after transmitting the * first packet in the ring. * * max_tx_desc=<val> - maximum number of transmit descriptors * (packets) transmitted before interrupting the host. * * max_rx_desc=<val> - maximum number of receive descriptors * (packets) received before interrupting the host. * * tx_ratio=<val> - 7 bit value (0 - 63) specifying the split in 64th * increments of the NIC's on board memory to be used for * transmit and receive buffers. For the 1MB NIC app. 800KB * is available, on the 1/2MB NIC app. 300KB is available. * 68KB will always be available as a minimum for both * directions. The default value is a 50/50 split. * dis_pci_mem_inval=<val> - disable PCI memory write and invalidate * operations, default (1) is to always disable this as * that is what Alteon does on NT. I have not been able * to measure any real performance differences with * this on my systems. Set <val>=0 if you want to * enable these operations. * * If you use more than one NIC, specify the parameters for the * individual NICs with a comma, ie. trace=0,0x00001fff,0 you want to * run tracing on NIC #2 but not on NIC #1 and #3. * * TODO: * * - Proper multicast support. * - NIC dump support. * - More tuning parameters. * * The mini ring is not used under Linux and I am not sure it makes sense * to actually use it. * * New interrupt handler strategy: * * The 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 * RX_MINI_THRES - maximum number of buffers in the mini ring * RX_JUMBO_THRES - maximum number of buffers in the jumbo 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_ret_csm is only written to by the interrupt * handler. The case to be aware of is when shutting down the device * and cleaning up where it is necessary to make sure that * start_xmit() is not running while this is happening. Well DaveM * informs me that this case is already protected against ... bye bye * Mr. Spin Lock, it was nice to know you. * * TX interrupts are now partly disabled so the NIC will only generate * TX interrupts for the number of coal ticks, not for the number of * TX packets in the queue. This should reduce the number of TX only, * ie. when no RX processing is done, interrupts seen.
*/
/* * 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.
