tg3: Break larger frags into 4k chunks for 5719

2011-07-28T05:39:32+00:00

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.

tg3: Add partial fragment unmapping code

2011-07-28T05:39:31+00:00

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.

tg3: Reintroduce tg3_tx_ring_info

2011-07-28T05:39:31+00:00

The following patches will require the use of an additional flag in the
ring_info structure.  The use of this flag is tx path specific, so this
patch defines a specialized ring_info structure.

tg3: Fix link flap at 100Mbps with EEE enabled

2011-07-21T19:36:15+00:00

This patch increases the scope of the EEE interoperability workaround
to include more asic revisions.  The workarond value is tuned to
workaround a link flap issue at 100Mbps.

tg3: Add function status reporting

2011-07-14T15:41:59+00:00

This patch adds code to update the status of the function to a common
location to the critical section added in the previous patch.

tg3: Create critical section around GPIO toggling

2011-07-14T15:41:59+00:00

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.

tg3: Determine PCI function number in one place

2011-07-14T15:41:59+00:00

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.

tg3: remove unnecessary read of PCI_CAP_ID_EXP

2011-06-28T04:38:45+00:00

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.

tg3: Migrate phy preprocessor defs to system defs

This patch changes to code to use some of the preprocessor
