187024144c phy: marvell: remove conflicting initializer
One line was apparently pasted incorrectly during a new feature patch:

drivers/net/phy/marvell.c:2090:15: error: initialized field overwritten [-Werror=override-init]
   .features = PHY_GBIT_FEATURES,

I'm removing the extraneous line here to avoid the W=1 warning and restore
the previous flags value, and I'm slightly reordering the lines for consistency
to make it less likely to happen again in the future. The ordering in the
array is still not the same as in the structure definition, instead I picked
the order that is most common in this file and that seems to make more sense
here.

e1636836e0 net: dummy: Introduce dummy virtual functions
The idea for this was born when testing VF support in iproute2 which was
impeded by hardware requirements. In fact, not every VF-capable hardware
driver implements all netdev ops, so testing the interface is still hard
to do even with a well-sorted hardware shelf.

To overcome this and allow for testing the user-kernel interface, this
patch allows to turn dummy into a PF with a configurable amount of VFs.

Since my patch series 'bus-agnostic-num-vf' has been accepted,
implementing the required interfaces is pretty straightforward: Iff
'num_vfs' module parameter was given a value >0, a dummy bus type is
being registered which implements the 'num_vf()' callback. Additionally,
a dummy parent device common to all dummy devices is registered which
sits on the above dummy bus.

Joint work with Sabrina Dubroca.

98d0f7b9ac mlxsw: spectrum: Add packet sample offloading support
Using the MPSC register, add the functions that configure port-based
packet sampling in hardware and the necessary datatypes in the
mlxsw_sp_port struct. In addition, add the necessary trap for sampled
packets and integrate with matchall offloading to allow offloading of the
sample tc action.

The current offload support is for the tc command:

tc filter add dev <DEV> parent ffff: \
	  matchall skip_sw \
	  action sample rate <RATE> group <GROUP> [trunc <SIZE>]

Where only ingress qdiscs are supported, and only a combination of
matchall classifier and sample action will lead to activating hardware
packet sampling.

b765234e72 net: stmmac: dwmac-meson8b: make the RGMII TX delay configurable
Prior to this patch we were using a hardcoded RGMII TX clock delay of
2ns (= 1/4 cycle of the 125MHz RGMII TX clock). This value works for
many boards, but unfortunately not for all (due to the way the actual
circuit is designed, sometimes because the TX delay is enabled in the
PHY, etc.). Making the TX delay on the MAC side configurable allows us
to support all possible hardware combinations.

This allows fixing a compatibility issue on some boards, where the
RTL8211F PHY is configured to generate the TX delay. We can now turn
off the TX delay in the MAC, because otherwise we would be applying the
delay twice (which results in non-working TX traffic).

41c1093f2e net: qcom/emac: rename emac_phy to emac_sgmii and move it
The EMAC has an internal PHY that is often called the "SGMII".  This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion.  In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.

Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only.  It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).

To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

44a4524c54 net: systemport: Add support for SYSTEMPORT Lite
Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware
is largely based on the full-blown SYSTEMPORT and differs in the following:

- no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at
  same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since
  we are always interfaced to an Ethernet switch which is fully Ethernet compliant
  shortcuts could be made

- 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt
  controller bank

- slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*)

- 256 RX descriptors (512 words) and 256 TX descriptors (not visible)

As a consequence of these two things, update the code paths accordingly to
differentiate the full-blown from the light version.

so no reason to disable them also. Removed lines have proved it.

So, no need in redundant check and interrupt disable.

aafc93a3b6 net: ethernet: ti: cpsw: remove dual check from common res usage function
Common res usage is possible only in case an interface is
running. In case of not dual emac here can be only one interface,
so while ndo_open and switch mode, only one interface can be opened,
thus if open is called no any interface is running ... and no common
res are used. So remove check on dual emac, it will simplify
code/understanding and will match the name it's called.

322dc6e067 macvlan: use netdev_is_rx_handler_busy instead of checking specific type
netdev_is_rx_handler_busy() check is a superset of netif_is_ipvlan_port()

c3262d9dec ipvlan: use netdev_is_rx_handler_busy instead of checking specific type
IPvlan checks if the master device is already used by checking a
specific device (here it's macvlan device). This is technically not
sufficient and it should just ensure the rx_handler is busy or not.
This would be a super check that includes macvlan and any other that
has already registered rx-handler.

0a327889f6 cxgb4: hide unused warnings
The two new variables are only used inside of an #ifdef and cause
harmless warnings when that is disabled:

drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c: In function 'init_one':
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:9: error: unused variable 'port_vec' [-Werror=unused-variable]
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:6: error: unused variable 'v' [-Werror=unused-variable]

This adds another #ifdef around the declarations.

dceeab0e52 mlx4: support __GFP_MEMALLOC for rx
Commit 04aeb56a17 ("net/mlx4_en: allocate non 0-order pages for RX
ring with __GFP_NOMEMALLOC") added code that appears to be not needed at
that time, since mlx4 never used __GFP_MEMALLOC allocations anyway.

As using memory reserves is a must in some situations (swap over NFS or
iSCSI), this patch adds this flag.

Note that this driver does not reuse pages (yet) so we do not have to
add anything else.

8a43c052c7 Revert "net: qcom/emac: configure the external phy to allow pause frames"
This reverts commit 3e88449344.

With commit 529ed12752 ("net: phy: phy drivers should not set
SUPPORTED_[Asym_]Pause"), phylib now handles automatically enabling
pause frame support in the PHY, and the MAC driver should follow suit.

Since the EMAC driver driver does this,  we no longer need to force
pause frames support.
