2010-02-10sky2: receive checksum refactoringstephen hemminger1-31/+28
Break the largish case for handling receive checksum into a separate function, and if there is a problem use dev_XXX routines to show which hardware is the problem. Turn one corner case into a BUG(). This only happens if the driver is expecting one behavior but the chip does the old behavior; only ever saw this when bringing up a new chip type and driver was buggy.

Change the resume path to use pci write config for a couple of reasons: 1. pci_write_config_dword() allows for more error checking of PCI health after resume. 2. better to toggle this register on all chip types, since that is what vendor driver does.

The fec driver was enabling receive buffer descriptor without allocating the buffers. Make sure the buffer descriptors are initialized to not start receiving packets. Open also calls fec_restart after the rx buffers are allocated. With the code in fec_restart, it zeroes out the buffer descriptors that have just been setup.

2010-02-04igb: make certain to reassign legacy interrupt vectors after resetAlexander Duyck1-15/+5
This change corrects an issue that will cause false hangs when using either 82575 or 82580 in legacy interrupt mode. The issue is caused when there is a slow traffic flow and an "ethtool -r" is executed while using legacy or MSI interrupts. MSI-X is not affected by this issue due to the fact that we were already reconfiguring the vectors after reset. If possible it would be best to push this for net-2.6 since it is resolving a bug but if that is not possible then net-next-2.6 will be fine.

2010-02-03can: mcp251x: Move to threaded interrupts instead of workqueues.Christian Pellegrin1-218/+203
This patch addresses concerns about efficiency of handling incoming packets. Handling of interrupts is done in a threaded interrupt handler which has a smaller latency than workqueues. This change needed a rework of the locking scheme that was much simplified. Some other (more or less longstanding) bugs are fixed: utilization of just half of the RX buffers, useless wait for interrupt on open, more reliable reset sequence. The MERR interrupt is not used anymore: it overloads the CPU in error-passive state without any additional information. One shot mode is disabled because it's not clear if it can be handled efficiently on this CAN controller.

2010-02-03net: macvtap driverArnd Bergmann3-0/+594
In order to use macvlan with qemu and other tools that require a tap file descriptor, the macvtap driver adds a small backend with a character device with the same interface as the tun driver, with a minimum set of features. Macvtap interfaces are created in the same way as macvlan interfaces using ip link, but the netif is just used as a handle for configuration and accounting, while the data goes through the chardev. Each macvtap interface has its own character device, simplifying permission management significantly over the generic tun/tap driver.

2010-02-03macvlan: allow multiple driver backendsArnd Bergmann1-64/+49

2010-02-03net: maintain namespace isolation between vlan and real deviceArnd Bergmann1-1/+1
In the vlan and macvlan drivers, the start_xmit function forwards data to the dev_queue_xmit function for another device, which may potentially belong to a different namespace.

2010-02-03ixgbe: Allocate driver resources per NUMA nodeJesse Brandeburg2-3/+36
The default policy for the current driver is to do all its memory allocation on whatever processor is running insmod/modprobe. This is less than optimal. This driver's default mode of operation will be to use each node for each subsequent transmit/receive queue. The most efficient allocation will be to then have the interrupts bound in such a way as to match up the interrupt of the queue to the cpu where its memory was allocated.

2010-02-03ixgbe: only process one ixgbe_watchdog_task at a time.John Fastabend2-13/+17
Processing multiple ixgbe_watchdog_task calls may cause the link_up variable and IXGBE_FLAG_NEED_LINK_UPDATE flag to be set incorrectly. In the worse case this is causing the netif_carrier_off to be called inappropriately which results in an interface that can't be brought up. Although schedule_work() will only schedule the task if it is not already on the work queue the WORK_STRUCT_PENDING bits are cleared just before calling the work function. This allows WORK_STRUCT_PENDING to be cleared, the work function to start and meanwhile schedule another task. This patch adds a mutex to the watchdog task. This bug is actualized by changing DCB settings or doing extended cable pull or reset tests.
