2018-02-04net: e1000: implement eth_write_hwaddrHannu Lounento
Implement programming MAC address to the hardware, i.e. external flash seen as EEPROM. MAC address is only written if it differs from what is already stored in flash or if reading the current MAC address fails.

Split the implementation of e1000_read_mac_addr into eeprom and register versions called by e1000_read_mac_addr. This allows for calling e1000_read_mac_addr when MAC address is needed with no constraints where it is read from, and for calling the register and, especially, the eeprom version directly in order to specify where to read the address from.

2012-12-15e1000e : Correct Rx Threshold granularityRuchika Gupta
In e1000e driver, Rx descriptor queue is used such that hardware can add only one descriptor at a time. So the WTHRESH granularity in RXDCTL should be set to single descriptor. This would ensure that every time controller fills a Rx descriptor, it is flushed to host memory. Earlier this granularity was in cache line units i.e 2 descriptors. This leads to controller always waiting for 2 descriptors before flushing them out. But since not more than one Rx BD is actually available , the accumulation condition never gets hit.

2011-10-28e1000: Allow direct access to the E1000 SPI EEPROM deviceKyle Moffett
As a part of the manufacturing process for some of our custom hardware, we are programming the EEPROMs attached to our Intel 82571EB controllers from software using U-Boot and Linux. This code provides several conditionally-compiled features to assist in our manufacturing process: CONFIG_CMD_E1000: This is a basic "e1000" command which allows querying the controller and (if other config options are set) performing EEPROM programming. In particular, with CONFIG_E1000_SPI this allows you to display a hex-dump of the EEPROM, copy to/from main memory, and verify/update the software checksum. CONFIG_E1000_SPI_GENERIC: Build a generic SPI driver providing the standard U-Boot SPI driver interface. This allows commands such as "sspi" to access the bus attached to the E1000 controller. Additionally, some E1000 chipsets can support user data in a reserved space in the E1000 EEPROM which could be used for U-Boot environment storage. CONFIG_E1000_SPI: The core SPI access code used by the above interfaces. For example, the following commands allow you to program the EEPROM from a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled): usb start fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin e1000 0 spi program $loadaddr 0 1024 e1000 0 spi checksum update Please keep in mind that the Intel-provided .eep files are organized as 16-bit words. When converting them to binary form for programming you must byteswap each 16-bit word so that it is in little-endian form. This means that when reading and writing words to the SPI EEPROM, the bit ordering for each word looks like this on the wire: Time >>> ------------------------------------------------------------------ ... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ... ------------------------------------------------------------------ (MSB is 15, LSB is 0).

2011-10-28e1000: Export core EEPROM access functions for SPI supportKyle Moffett
A followup patch will be adding a configurable feature to enable programming of E1000 EEPROMs from the command line or via the generic U-Boot SPI interface. In order for it to work it needs access to certain E1000-internal functions, so export those in the e1000.h header file.

2011-10-28e1000: Restructure and streamline PCI device probingKyle Moffett
By allocating the e1000 device structures much earlier, we can easily generate better error messages and siginficantly clean things up. The only user-visable change (aside from reworded error messages) is that a detected e1000 device which fails to initialize due to software or hardware error will still be allocated a device number. As one example, consider a system with 2 e1000 PCI devices where the first controller has a corrupted EEPROM. Using the old code the second controller would be "e1000#0", while with this change it would be "e1000#1". This change should hopefully make such EEPROM errors much more straightforward to handle correctly in boot scripts and the like. It is also necessary for a followup patch which allows SPI programming of an e1000 controller's EEPROM even if the checksum is invalid.
