The MDIO bus drivers for the UCC and gianfar ethernet controllers are
essentially the same. There's no reason to duplicate that much code.Signed-off-by: Andy Fleming

VLAN filtering allows the hypervisor to drop packets from VLANs
that we're not a part of, further reducing the number of extraneous
packets recieved. This makes use of the VLAN virtqueue command class.
The CTRL_VLAN feature bit tells us whether the backend supports VLAN
filtering.Signed-off-by: Alex Williamson

Make use of the MAC control virtqueue class to support a MAC
filter table. The filter table is managed by the hypervisor.
We consider the table to be available if the CTRL_RX feature
bit is set. We leave it to the hypervisor to manage the table
and enable promiscuous or all-multi mode as necessary depending
on the resources available to it.Signed-off-by: Alex Williamson

Make use of the RX_MODE control virtqueue class to enable the
set_rx_mode netdev interface. This allows us to selectively
enable/disable promiscuous and allmulti mode so we don't see
packets we don't want. For now, we automatically enable these
as needed if additional unicast or multicast addresses are
requested.Signed-off-by: Alex Williamson

This will be used for RX mode, MAC filter table, VLAN filtering, etc...
The control transaction consists of one or more "out" sg entries and
one or more "in" sg entries. The first out entry contains a header
defining the class and command. Additional out entries may provide
data for the command. The last in entry provides a status response
back from the command.Virtqueues typically run asynchronous, running a callback function
when there's data in the channel. We can't readily make use of this
in the command paths where we need to use this. Instead, we kick
the virtqueue and spin. The kick causes an I/O write, triggering an
immediate trap into the hypervisor.Signed-off-by: Alex Williamson

S2IO driver is printing dev->name before the name being allocated, which
display eth%d instead of eth0, eth1, etc. Example:eth%d: Enabling MSIX failed
eth%d: MSI-X requested but failed to enableThis patch just change eth%d to s2io.

On non-x86 platforms it is possible to run out of DMA mapping resources.

This workaround is not needed. It was inherited from sk98lin driver but only
applies to an early development version of the chip that is not supported
by sky2. The workaround required an unnecessary pci read which hurts performanceSigned-off-by: Stephen Hemminger

Our current MSI-X allocation mechanism does not support new hardware
at all. It also isn't getting the actual number of supported MSI-X vectors
from the device.This patch allows the number of MSI-X vectors to be specific to a device,
plus it gets the number of MSI-X vectors available from PCIe configuration

In most cases (e.g. PCI drivers) MDIO and MAC controllers are
represented by the same device. But for SOC ethernets we have
separate devices. So, in SOC case, checking whether MDIO
controller may wakeup is not only makes little sense, but also
prevents us from doing per-netdevice wakeup management.This patch reworks suspend/resume code so that now it checks
for net device's wakeup flags, not MDIO controller's ones.Each netdevice should manage its wakeup flags, and phylib will
decide whether suspend an attached PHY or not.Signed-off-by: Anton Vorontsov

Some platforms (for example pcm037) do not have an EEPROM fitted,
instead storing their mac address somewhere else. The bootloader
fetches this and configures the ethernet adapter before the kernel is
started.This patch allows a platform to indicate to the driver via the
SMSC911X_SAVE_MAC_ADDRESS flag that the mac address has already been
configured via such a mechanism, and should be saved before resetting
the chip.Signed-off-by: Steve Glendinning
