2009-06-02forcedeth: add phy_power_down parameter, leave phy powered up by default (v2)Ed Swierk
Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

This patch adds a generic driver for SJA1000 chips on the OpenFirmware platform bus found on embedded PowerPC systems.

2009-06-01can: sja1000: stop misusing member base_addr of struct net_deviceWolfgang Grandegger
As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device".

2009-05-29net: convert unicast addr listJiri Pirko
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.

Writes to the DMA descriptors may sit in the internal Blackfin data buffers and not actually be available when the DMA engine goes to fetch them. This does not typically happen, but when dealing with short/fast packets such as UDP and polling KGDB, this occurs much more frequently. Same goes for heavy loads as seen by netperf tests or large scp transfers. So force the buffers to drain with SSYNC otherwise we get random malformed packets.

Commit 5e68b772e6efd189d6aca76f6872fb75d51ace60 cxgb3: map entire Rx page, feed map+offset to Rx ring. introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR() and related macros as no-ops. Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

2009-05-28wimax/i2400m: usb: fix device reset on autosuspend while not yet idleInaky Perez-Gonzalez
When the i2400m is connected to a network, the host interface (USB) cannot be suspended. For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is requested (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

Functions i2400m_report_tlv*() are only called from i2400m_report_hook(), called in a workqueue by i2400m_report_hook_work(). The scheduler checks for device readiness before scheduling. Added an extra check for readiness in i2400m_report_hook_work(), which makes all the checks down the line redundant. Obviously the device state could change in the middle, but error handling would take care of that. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>

By running 'echo 1 > /sys/kernel/debug/wimax:wmxX/i2400m/trace_msg_from_user', the driver will echo to user space all the commands being sent to the device from user space, along with the responses. However, this only helps with the commands being sent from user space; with this patch, the trace hook is moved to i2400m_msg_to_dev(), which is the single access point for running commands to the device (both by user space and the kernel driver). This allows better debugging by having a complete stream of commands/acks and reports. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
2009-05-28wimax/i2400m: trace commands sent from user space on the "echo" pipeInaky Perez-Gonzalez
When commands are sent from user space, trace both the command sent and the answer received over the "echo" pipe instead of over the "trace" pipe when command tracing is enabled. As well, when the device sends a reports/indications, send it over the "echo" pipe. The "trace" pipe is used by the device to send firmware traces; gets confusing. Another named pipe makes it easier to split debug information. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
2009-05-28wimax/i2400m: generate fake source MAC address with random_ether_addr()Inaky Perez-Gonzalez
The WiMAX i2400m driver needs to generate a fake source MAC address to fake an ethernet header (for destination, the card's MAC is used). This is the source of the packet, which is the basestation it came from. The basestation's mac address is not usable for this, as it uses its own namespace and it is not always available. Currently the fake source MAC address was being set to all zeros, which was causing trouble with bridging. Use random_ether_addr() to generate a proper one that creates no trouble.
