* | | can: sja1000: stop misusing member base_addr of struct net_deviceWolfgang Grandegger2009-06-015-98/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warning messages coming from rtl8150 driver can flood the console and make a DTV/set-top-box unable to decode video/audio frames. 'Pegasus' driver handles this situation similarly, preventing this from happening there. It happens with a low cost BCM MIPS embedded platform, whenever timeout errors were coming from usbnet device, making platform unusable for viewer watching.

* | | net: convert unicast addr listJiri Pirko2009-05-2910-48/+53

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.

| * | | wimax/i2400m: usb: fix device reset on autosuspend while not yet idleInaky Perez-Gonzalez2009-05-281-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Modifications are added to allow a different return value for modules that just haven't been plugged in yet. Other functions were updated to allow correct logging.

The RNBC (Receive No Buffers Count) register for the 82576, indicate that frames were received when there were no available buffers in host memory to store those frames (receive descriptor head and tail pointers were equal). The packet is still received by the NIC if there is space in the FIFO on the NIC. As the RNBC value is not a packet drop, the driver stores this value in net_stats.rx_fifo_errors to indicate that there were no system buffers available for the incoming packet. Actual dropped packets are counted in the MPC value. Saving the stats in dev->net_stats makes it visible via /proc/net/dev as "fifo", and thus viewable to ifconfig as "overruns" and 'netstat -i' as "RX-OVR". The Receive No Buffers Count (RNBC) can already be queried by ethtool -S as "rx_no_buffer_count".

* | | | igb: Implement reading of reg RQDPC (Receive Queue Drop Packet Count)Jesper Dangaard Brouer2009-05-263-10/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the previous patches from Jesper Dangaard Brouer <hawk@comx.dk> Implement reading the per queue drop stats register RQDPC (Receive Queue Drop Packet Count). It counts the number of packets dropped by a queue due to lack of descriptors available. Notice RQDPC (Receive Queue Drop Packet Count) stats only gets incremented, if the DROP_EN bit it set (in the SRRCTL register for that queue). If DROP_EN bit is NOT set, then the some what equivalent count is stored in RNBC (not per queue basis). The RQDPC register is only 12 bit, thus the precision might suffer due to overrun in-netween the watchdog polling interval.
