* igb: add link check functionAlexander Duyck2009-02-07
| | | | | | | | | | Add a link check function to contain all activities related to verifying that the link is present. The current approach is a bit cludgy and needs to be cleaned up.

* igb: remove check for needing an io portAlexander Duyck2009-02-07
| | | | | | | | | | | | | Since igb supports only pci-e nics and there is no plan to support any legacy pci parts in the driver there isn't really much need for checking to see if an io port is needed. In the unlikely event that we do begin supporting legacy pci parts then we can see about adding this code back to the driver.

* igb: move initialization of number of queues into set_interrupt_capabilityAlexander Duyck2009-02-07
| | | | | | | | | | | | This patch moves the initialization of the number of queues into set_interrupt_capability. This allows the number of queues to increase in the unlikely event that the system initially fails to allocate enough msi-x interrupts, does a suspend/resume, and then can allocate enough interrupts on resume.

* ixgbe: Fix a set_num_queues() bug that can result in num_(r|t)x_queues = 0Peter P Waskiewicz Jr2009-02-07
| | | | | | | | | | | | Now that our set_num_queues() routines for each feature are re-entrant, and can be called at any point, they shouldn't zero out the feature's indices or mask bits. Subsequent calls into those routines for those features can result in zero Rx and Tx queues being assigned, causing a panic later in driver reinitialization.

* tun: Limit amount of queued packets per deviceHerbert Xu2009-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike a normal socket path, the tuntap device send path does not have any accounting. This means that the user-space sender may be able to pin down arbitrary amounts of kernel memory by continuing to send data to an end-point that is congested. Even when this isn't an issue because of limited queueing at most end points, this can also be a problem because its only response to congestion is packet loss. That is, when those local queues at the end-point fills up, the tuntap device will start wasting system time because it will continue to send data there which simply gets dropped straight away. Of course one could argue that everybody should do congestion control end-to-end, unfortunately there are people in this world still hooked on UDP, and they don't appear to be going away anywhere fast. In fact, we've always helped them by performing accounting in our UDP code, the sole purpose of which is to provide congestion feedback other than through packet loss. This patch attempts to apply the same bandaid to the tuntap device. It creates a pseudo-socket object which is used to account our packets just as a normal socket does for UDP. Of course things are a little complex because we're actually reinjecting traffic back into the stack rather than out of the stack. The stack complexities however should have been resolved by preceding patches. So this one can simply start using skb_set_owner_w. For now the accounting is essentially disabled by default for backwards compatibility. In particular, we set the cap to INT_MAX. This is so that existing applications don't get confused by the sudden arrival EAGAIN errors. In future we may wish (or be forced to) do this by default.

The control transaction consists of one or more "out" sg entries and one or more "in" sg entries. The first out entry contains a header defining the class and command. Additional out entries may provide data for the command. The last in entry provides a status response back from the command. Virtqueues typically run asynchronous, running a callback function when there's data in the channel. We can't readily make use of this in the command paths where we need to use this. Instead, we kick the virtqueue and spin. The kick causes an I/O write, triggering an immediate trap into the hypervisor.
