Board Compatibility\n-\n-This device driver is designed for the Intel i82557 \"Speedo3\" chip, Intel's\n-single-chip fast Ethernet controller for PCI, as used on the Intel\n-EtherExpress Pro 100 adapter.\n-\n-II. Board-specific settings\n-\n-PCI bus devices are configured by the system at boot time, so no jumpers\n-need to be set on the board. The system BIOS should be set to assign the\n-PCI INTA signal to an otherwise unused system IRQ line. While it's\n-possible to share PCI interrupt lines, it negatively impacts performance and\n-only recent kernels support it.\n-\n-III. Driver operation\n-\n-IIIA. General\n-The Speedo3 is very similar to other Intel network chips, that is to say\n-\"apparently designed on a different planet\". This chips retains the complex\n-Rx and Tx descriptors and multiple buffers pointers as previous chips, but\n-also has simplified Tx and Rx buffer modes. This driver uses the \"flexible\"\n-Tx mode, but in a simplified lower-overhead manner: it associates only a\n-single buffer descriptor with each frame descriptor.\n-\n-Despite the extra space overhead in each receive skbuff, the driver must use\n-the simplified Rx buffer mode to assure that only a single data buffer is\n-associated with each RxFD. The driver implements this by reserving space\n-for the Rx descriptor at the head of each Rx skbuff.\n-\n-The Speedo-3 has receive and command unit base addresses that are added to\n-almost all descriptor pointers. The driver sets these to zero, so that all\n-pointer fields are absolute addresses.\n-\n-The System Control Block (SCB) of some previous Intel chips exists on the\n-chip in both PCI I/O and memory space. This driver uses the I/O space\n-registers, but might switch to memory mapped mode to better support non-x86\n-processors.\n-\n-IIIB. Transmit structure\n-\n-The driver must use the complex Tx command+descriptor mode in order to\n-have a indirect pointer to the skbuff data section. Each Tx command block\n-(TxCB) is associated with two immediately appended Tx Buffer Descriptor\n-(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the\n-speedo_private data structure for each adapter instance.\n-\n-The newer i82558 explicitly supports this structure, and can read the two\n-TxBDs in the same PCI burst as the TxCB.\n-\n-This ring structure is used for all normal transmit packets, but the\n-transmit packet descriptors aren't long enough for most non-Tx commands such\n-as CmdConfigure. This is complicated by the possibility that the chip has\n-already loaded the link address in the previous descriptor. So for these\n-commands we convert the next free descriptor on the ring to a NoOp, and point\n-that descriptor's link to the complex command.\n-\n-An additional complexity of these non-transmit commands are that they may be\n-added asynchronous to the normal transmit queue, so we disable interrupts\n-whenever the Tx descriptor ring is manipulated.\n-\n-A notable aspect of these special configure commands is that they do\n-work with the normal Tx ring entry scavenge method. The Tx ring scavenge\n-is done at interrupt time using the 'dirty_tx' index, and checking for the\n-command-complete bit. While the setup frames may have the NoOp command on the\n-Tx ring marked as complete, but not have completed the setup command, this\n-is not a problem. The tx_ring entry can be still safely reused, as the\n-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.\n-\n-Commands may have bits set e.g. CmdSuspend in the command word to either\n-suspend or stop the transmit/command unit. This driver always flags the last\n-command with CmdSuspend, erases the CmdSuspend in the previous command, and\n-then issues a CU_RESUME.\n-Note: Watch out for the potential race condition here: imagine\n-\terasing the previous suspend\n-\t\tthe chip processes the previous command\n-\t\tthe chip processes the final command, and suspends\n-\tdoing the CU_RESUME\n-\t\tthe chip processes the next-yet-valid post-final-command.\n-So blindly sending a CU_RESUME is only safe if we do it immediately after\n-after erasing the previous CmdSuspend, without the possibility of an\n-intervening delay. Thus the resume command is always within the\n-interrupts-disabled region. This is a timing dependence, but handling this\n-condition in a timing-independent way would considerably complicate the code.\n-\n-Note: In previous generation Intel chips, restarting the command unit was a\n-notoriously slow process. This is presumably no longer true.\n-\n-IIIC. Receive structure\n-\n-Because of the bus-master support on the Speedo3 this driver uses the new\n-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.\n-This scheme allocates full-sized skbuffs as receive buffers. The value\n-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to\n-trade-off the memory wasted by passing the full-sized skbuff to the queue\n-layer for all frames vs. the copying cost of copying a frame to a\n-correctly-sized skbuff.\n-\n-For small frames the copying cost is negligible (esp. considering that we\n-are pre-loading the cache with immediately useful header information), so we\n-allocate a new, minimally-sized skbuff. For large frames the copying cost\n-is non-trivial, and the larger copy might flush the cache of useful data, so\n-we pass up the skbuff the packet was received into.\n-\n-IV. Notes\n-\n-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement\n-that stated that I could disclose the information. But I still resent\n-having to sign an Intel NDA when I'm helping Intel sell their own product!\n-\n-*/\n-\n-static int speedo_found1(struct pci_dev *pdev, void __iomem *ioaddr, int fnd_cnt, int acpi_idle_state);\n-\n-/* Offsets to the various registers.\n- All accesses need not be longword aligned. */\n-enum speedo_offsets {\n-\tSCBStatus = 0, SCBCmd = 2,\t/* Rx/Command Unit command and status. */\n-\tSCBIntmask = 3,\n-\tSCBPointer = 4,\t\t\t\t/* General purpose pointer. */\n-\tSCBPort = 8,\t\t\t\t/* Misc. commands and operands. */\n-\tSCBflash = 12, SCBeeprom = 14, /* EEPROM and flash memory control. */\n-\tSCBCtrlMDI = 16,\t\t\t/* MDI interface control. */\n-\tSCBEarlyRx = 20,\t\t\t/* Early receive byte count. */\n-};\n-/* Commands that can be put in a command list entry. */\n-enum commands {\n-\tCmdNOp = 0, CmdIASetup = 0x10000, CmdConfigure = 0x20000,\n-\tCmdMulticastList = 0x30000, CmdTx = 0x40000, CmdTDR = 0x50000,\n-\tCmdDump = 0x60000, CmdDiagnose = 0x70000,\n-\tCmdSuspend = 0x40000000,\t/* Suspend after completion. */\n-\tCmdIntr = 0x20000000,\t\t/* Interrupt after completion. */\n-\tCmdTxFlex = 0x00080000,\t\t/* Use \"Flexible mode\" for CmdTx command. */\n-};\n-/* Clear CmdSuspend (1<<30) avoiding interference with the card access to the\n- status bits.
