2011-07-27tg3: Break larger frags into 4k chunks for 5719Matt Carlson1-0/+1
The 5719 has bug where RDMAs larger than 4k can cause problems. This patch works around the problem by dividing larger DMA requests into something the hardware can handle.

2011-07-27tg3: Add partial fragment unmapping codeMatt Carlson1-0/+1
The following patches are going to break skb fragments into smaller sizes. This patch attempts to make the change easier to digest by only addressing the skb teardown portion. The patch modifies the driver to skip over any BDs that have a flag set that indicates the BD isn't the beginning of an skb fragment. Such BDs were a result of segmentation and do not need a pci_unmap_page() call.

2011-07-14tg3: Create critical section around GPIO togglingMatt Carlson1-0/+1
The code that performs the power source switching will need to consider the status of the other devices before making any switches. The status updates and power source switching will need to be an atomic operation, so a critical section will be needed. This patch establishes the critical section through a CPMU mutex.

2011-07-14tg3: Determine PCI function number in one placeMatt Carlson1-0/+1
tg3 devices will need to know exactly what function number they are so that they can communicate their status to the other functions. In a KVM environment, the function number of a device presented by the kernel might not be the true function number, so an alternative method to determine the function number is needed. This patch used to contain an implementation for the alternative method, but recently we discovered a hardware bug that renders it incorrect. While new method is not yet known, it is still useful to consolidate the code that determines the PCI function to one location and use the results throughout the code.

2011-06-27tg3: remove unnecessary read of PCI_CAP_ID_EXPJon Mason1-4/+1
The PCIE capability offset is saved during PCI bus walking. Use the value from pci_dev instead of checking in the driver and saving it off the the driver specific structure. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. v2 of the patch re-adds the PCI_EXPRESS flag and adds comments describing why it is necessary.

2011-04-21tg3: Adjust rx prod ring bd replenish thresholdsMatt Carlson1-2/+7
The oldest tg3 devices had large rx producer ring BD caches. Back then, it made sense to make the BD cache replenish threshold only a function of the number of rx buffers posted by the driver. Since then, the BD cache sizes have shrunk to 25% of their original size and, in some cases, the ring sizes have quadrupled in size. Under such conditions, static BD cache replenish thresholds no longer match the hardware constraints. This patch attempts to factor in the BD cache size into the bd cache replenish strategy, taking the existing hardware bugs into account.
