net: phy: smsc: Re-enable EDPD mode for LAN87xx
This patch re-enables Energy Detect Power Down (EDPD) mode for the
LAN8710/LAN8720. EDPD mode was disabled in a previous commit,
(
b629820d18fa65cc598390e4b9712fd5f83ee693), because it was causing the
PHY to not be able to detect a link when cold started without a cable
connected.
The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of
each other in order to set the ENERGYON bit and exit EDPD mode. If a
link partner does send the pulses within this interval, the PHY will
remained powered down.
This workaround will manually toggle the PHY on/off upon calls to
read_status in order to generate link test pulses if the link is down.
If a link partner is present, it will respond to the pulses, which will
cause the ENERGYON bit to be set and will cause the EDPD mode to be
exited.

ioat: Do not enable DCA if tag map is invalid
I have encountered several systems that have an invalid tag map. This
invalid tag map results in only two tags being generated 0x1F which is
usually applied to the first core in a Hyper-threaded pair and 0x00 which
is applied to the second core in a Hyper-threaded pair. The net result of
all this is that DCA causes significant cache thrash because the 0x1F tag
will send traffic to the second socket, which the 0x00 tag will not DCA tag
the frame resulting in no benefit.
For now the best solution from the driver's perspective is to just disable
DCA if the tag map is invalid. The correct solution for this would be to
have the BIOS on affected systems updated so that the correct tags are
generated for a given APIC ID.

CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma,
cpsw, etc... These sub-modules are also used in some of Davinci family
of devices. Now based on requirement, use-case and available technology
nodes the integration of these sub-modules varies across devices.
So coming back to Linux net driver, currently separate and independent
platform devices & drivers for CPSW and MDIO is implemented. In case of
Davinci they both has separate control, from resources perspective,
like clock.
In case of AM33XX, the resources are shared and only one register
bit-field is provided to control module/clock enable/disable, makes it
difficult to handle common resource.
So the solution here implemented in this patch is,
Create parent<->child relationship between both the drivers, making
CPSW as a parent and MDIO as its child and enumerate all the child nodes
under CPSW module.
Both the drivers will function exactly the way it was operating before,
including runtime-pm functionality. No change is required in MDIO driver
(for that matter to any child driver).
As this is only supported during DT boot, the parent<->child relationship
is created and populated in DT execution flow. The only required change
is inside DTS file, making MDIO as a child to CPSW node.

old message used IFLA_PROTINFO and new one uses

The code adapts to old format requests, and therefore stays
compatible with user mode RSTP daemon. Since the type field

This patch allows clients to roam multiple times within the same

1) packets are always directed to the node that was originally

to the correct destination at any point in time;
2) the client flags handling mechanism has been properly modified
in order to allow multiple roamings withinin the same orig-int.
Therefore flags are now set properly even in this scenario.

tt_poss_change is a node-wide flag which tells whether the node is in a roaming
state (a client recently moved to/away from it) in order to let it apply special
re-routing rules. However this flag does not give a clear idea of the current
state because it is not possible to understand *which client* is actually
involved in the roaming. For this reason a better approach has been chosen:
instead of using a node-wide variable, the roaming state is now given by a
per-tt_entry ROAM flag which, in case of packet coming through the node, tells
the node whether the real destination is in roaming state or not.
With this flag change, batadv_check_unicast_ttvn() has also been rearranged in
order to better fit the new re-routing logic and to be much more readable.

napi_gro_receive shouldn't be called from netpoll context. Doing
so was causing kernel panics when jumbo frames larger than 2K were set.
Add a flag to check if the Rx ring processing is occurring from interrupt
context or from netpoll context and call netif_rx() if in the polling
context.

ixgbe: Do not use DCA to prefetch the entire packet into the cache
The way the code was previously written it was causing DCA to prefetch the
entire packet into the cache when it was enabled. That is excessive as we
only really need the headers.
We are now prefetching the headers via software so doing this from DCA would
be redundant anyway. So clear the bit that was causing us to prefetch the
packet data and instead only use DCA for the descriptor rings.
