2010-04-26tg3: Fix INTx fallback when MSI failsAndre Detsch1-0/+1
tg3: Fix INTx fallback when MSI fails MSI setup changes the value of irq_vec in struct tg3 *tp. This attribute must be taken into account and restored before we try to do a new request_irq for INTx fallback. In powerpc, the original code was leading to an EINVAL return within request_irq, because the driver was trying to use the disabled MSI virtual irq number instead of tp->pdev->irq.

2010-04-13tg3: Re-inline VLAN tags when appropriateMatt Carlson1-11/+33
The tg3 driver is written so that VLAN tagged packets can be accepted, even if CONFIG_VLAN_8021Q or CONFIG_VLAN_8021Q_MODULE is not defined. (Think raw interfaces.) If the device has ASF support enabled, the firmware requires the driver to enable VLAN tag stripping. If VLAN tagging is not explicitly supported by the kernel and ASF is enabled, the driver will have to reinject the VLAN tag back into the packet stream.

2010-04-13tg3: Optimize rx double copy testMatt Carlson1-7/+25
On a PCIX bus, the 5701 has a bug which requires the driver to double copy all rx packets. The rx code uses the rx_offset device member as a flag to determine if this workaround should take effect. The following patch will modify the rx_offset member such that this test will become less clear. The patch starts by integrating the workaround check into the packet length check. It rounds out the implementation by relaxing the workaround restrictions if the platform has efficient unaligned accesses.
