2011-08-11intel: Move the Intel wired LAN driversJeff Kirsher1-941/+0
Moves the Intel wired LAN drivers into drivers/net/ethernet/intel/ and the necessary Kconfig and Makefile changes. Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2011-08-04intel drivers: repair missing flush operationsJesse Brandeburg1-0/+1
after review of all intel drivers, found several instances where drivers had the incorrect pattern of: memory mapped write(); delay(); which should always be: memory mapped write(); write flush(); /* aka memory mapped read */ delay(); explanation: The reason for including the flush is that writes can be held (posted) in PCI/PCIe bridges, but the read always has to complete synchronously and therefore has to flush all pending writes to a device. If a write is held and followed by a delay, the delay means nothing because the write may not have reached hardware (maybe even not until the next read) Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2011-06-21ixgbe: add support for Dell CEMEmil Tantilov1-0/+1

2011-06-21ixgbe: consolidate packet buffer allocationJohn Fastabend1-0/+1
Consolidate packet buffer allocation currently being done in the DCB path and main path. This allows the feature set and packet buffer requirements to be done once. This is prep work to allow DCB to coexist with other features namely, flow director.

2011-05-04ixgbe: improve EEPROM read/write operationsEmil Tantilov1-6/+61
Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Evan Swanson <evan.swanson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2011-04-14ixgbe: DCB, misallocated packet buffer size with X540 deviceJohn Fastabend1-1/+2
The X540 device has a smaller packet buffer but the DCB configuration never took this into account. Under stress this can result in the DMA engine hanging and TX Unit hang occurring to reset the device. This patch reworks the packet buffer allocation routine used for DCB on 82599 and X540 devices to account for RX packet buffer sizes. This fixes the immediate hang. We should consolidate the various hardware specific routines for configuring features into a single routine. This will make it much harder to miss feature cases like this.

2011-04-14ixgbe: make device_caps() genericEmil Tantilov1-1/+1
x540 has the same device capability word in the EEPROM as 82599. This patch renames ixgbe_get_device_caps_82599 to ixgbe_get_device_caps_generic, moves it to ixgbe_common.h and sets up the function pointer for x540.

2011-04-14ixgbe: fix semaphores in eeprom routines for x540Emil Tantilov1-45/+109
HW can upload EEPROM content from flash while in a middle of checksum calculation. Take NVM ownership for the whole process of checksum update. Call ixgbe_read_eerd_generic() and ixgbe_write_eewr_generic() directly to avoid double take of semaphores which leads to long loading times.

2011-03-03ixgbe: add function pointer for semaphore functionDon Skidmore1-2/+4
The X540 devices grabs semaphores differently than 82599 and 82598 devices do. They do however also grab them in allot of the same functions. So I'm adding a new MAC operation function pointer to allow us to use the correct function based on our MAC type. I'm also changing all the semaphore calls to use this new function pointer.

2011-03-03ixgbe: cleanup X540 PHY reset function pointerDon Skidmore1-1/+1
The X540 PHY reset pointer isn't currently used which is a good thing as it wouldn't work as implemented. On top of that the X540 firmware is written with the assumption that is does not need to be reset for proper initialization so it's not needed. I'm just assigning the pointer at NULL as the current implementation is rather misleading.

2011-03-03ixgbe: Add ability to double reset on failure to clear master enableEmil Tantilov1-5/+15
Double resets are required for recovery from certain error conditions. Between resets, it is necessary to stall to allow time for any pending HW events to complete. We use 1usec since that is what is needed for ixgbe_disable_pcie_master(). The second reset then clears out any effects of those events.
