The device match tables for both the xgene_enet driver and its phy driver
have forward declarations that declare an array without a length, leading
to a clang warning when they are not followed by an actual defitinition:
drivers/net/ethernet/apm/xgene/../../../phy/mdio-xgene.h:135:34: warning: tentative array definition assumed to have one element
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning: tentative array definition assumed to have one element
The declarations for the mdio driver are even in a header file, so they
cause duplicate definitions of the tables for each file that includes
them.
This removes all four forward declarations and moves the actual
definitions up a little, so they are in front of their first user. For
the OF match tables, this means having to remove the #ifdef around them,
and passing the actual structure into of_match_device(). This has no
effect on the generated object code though, as the of_match_device
function has an empty stub that does not evaluate its argument, and
the symbol gets dropped either way.

Recent commit 3439352916 ("be2net: fix MAC addr setting on privileged
BE3 VFs") allows privileged BE3 VFs to set its MAC address during
initialization. Although the initial MAC for such VFs is already
programmed by parent PF the subsequent setting performed by VF is OK,
but in certain cases (after fresh boot) this command in VF can fail.
The MAC should be initialized only when:
1) no MAC is programmed (always except BE3 VFs during first init)
2) programmed MAC is different from requested (e.g. MAC is set when
interface is down). In this case the initial MAC programmed by PF
needs to be deleted.
The adapter->dev_mac contains MAC address currently programmed in HW so
it should be zeroed when the MAC is deleted from HW and should not be
filled when MAC is set when interface is down in be_mac_addr_set() as
no programming is performed in this case.
Example of failure without the fix (immediately after fresh boot):
# ip link set eth0 up <- eth0 is BE3 PF
be2net 0000:01:00.0 eth0: Link is Up
# echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create 1 VF
...
be2net 0000:01:04.0: Emulex OneConnect(be3): VF port 0
# ip link set eth8 up <- eth8 is created privileged VF

So far were were allocating struct bgmac in 3 places: platform code,
bcma code and shared bgmac_enet_probe function. The reason for this was
bgmac_enet_probe:
1) Requiring early-filled struct bgmac
2) Calling alloc_etherdev on its own in order to use netdev_priv later
This solution got few drawbacks:
1) Was duplicating allocating code
2) Required copying early-filled struct
3) Resulted in platform/bcma code having access only to unused struct
Solve this situation by simply extracting some probe code into the new
bgmac_alloc function.

Some Hypervisors detach VFs from VMs by instantly causing an FLR event
to be generated for a VF.
In the mlx4 case, this will cause that VF's comm channel to be disabled
before the VM has an opportunity to invoke the VF device's "shutdown"
method.
The result is that the VF driver on the VM will experience a command
timeout during the shutdown process when the Hypervisor does not deliver
a command-completion event to the VM.
To avoid FW command timeouts on the VM when the driver's shutdown method
is invoked, we detect the absence of the VF's comm channel at the very
start of the shutdown process. If the comm-channel has already been
disabled, we cause all FW commands during the device shutdown process to
immediately return success (and thus avoid all command timeouts).

In spite of switching to paged allocation of Rx buffers, the driver still
called dma_unmap_single() in the Rx queues tear-down path.
The DMA region unmapping code in free_skb_rx_queue() basically predates
the introduction of paged allocation to the driver. While being refactored,
it apparently hasn't reflected the change in the DMA API usage by its
counterpart gfar_new_page().
As a result, setting an interface to the DOWN state now yields the following:

Even though the issue was discovered in 4.9 kernel, the code in question
is identical in the current net and net-next trees.

The SGMII (internal PHY) can report decode errors via an interrupt. It
can also report autonegotiation status changes, but we don't need to track
those. The SGMII can recover automatically from most decode errors, so
we only reset the interface if we get multiple consecutive errors.
It's possible for bogus decode errors to be reported while the link is
being brought up. The interrupt is registered when the interface is
opened, and it's enabled after the link is up.

The EMAC driver does not support wake-on-lan, but there is still
code left-over that partially enables it. Remove that code and a few
macros that support it.
