As the driver breaks large skb fragments into smaller submissions to the hardware, there is a new danger that BDs might get exhausted before all fragments have been mapped.

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.

Commit f2096f94, entitled "tg3: Add 5720 H2BMC support", needed to add code to preserve some bits set by firmware.

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.

Currently pci_set_power_state() does not return useful return codes for transitions to the D0 power state. If a device refuses to go into D0, the PCI layer issues a warning but returns success. Entering into D0 is a requirement for correct operation of tg3 devices though. If the PCI layer should be changed to return an error code for this type of failure, the tg3 driver would be interested in catching it and reacting to it. This patch makes the necessary modifications. Signed-off-by: NMatt Carlson <mcarlson@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
