tg3 commit e7126997 entitled
"tg3: Preserve PCIe MPS setting for new devs" attempted to ensure the
PCIe link negotiated Maximum Payload Size (MPS) setting was 128 bytes
for all devices that didn't support higher speeds.  The 5784 device was
mistakenly added to this list when it shouldn't have.  This patch
removes the 5784 ASIC rev devices from that list.

The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

This attribute must be taken into account and restored before

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.

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.
