Depending on NETFILTER is not sufficient to ensure the presence of the
'mark' field in nf_conn, also needs to depend on NF_CONNTRACK_MARK.

My previous patch to this file changed the code to be bug-compatible
towards userspace. Unless userspace (which I wasn't able to find)
implements the dump reader by hand in a wrong way, this isn't needed.
If it uses libnl or similar code putting multiple messages into a
single SKB is far more efficient.
Change the code to do this. While at it, also clean it up and don't
use so many variables - just store the address in the callback args
directly.

The commit (3d125f9c91c5) cause i.MX6SX sdb enet cannot work. The cause is
the commit add mdio node with un-correct phy address.
The patch just correct i.MX6sx sdb board enet phy address.

This tc action allows you to retrieve the connection tracking mark
This action has been used heavily by openwrt for a few years now.
There are known limitations currently:
doesn't work for initial packets, since we only query the ct table.
Fine given use case is for returning packets
no implicit defrag.
frags should be rare so fix later..
won't work for more complex tasks, e.g. lookup of other extensions
since we have no means to store results
we still have a 2nd lookup later on via normal conntrack path.
This shouldn't break anything though since skb->nfct isn't altered.
V2:
remove unnecessary braces (Jiri)
change the action identifier to 14 (Jiri)
Fix some stylistic issues caught by checkpatch
V3:
Move module params to bottom (Cong)
Get rid of tcf_hashinfo_init and friends and conform to newer API (Cong)

DSA-enabled master network devices with a switch tagging protocol should
strip the protocol specific format before handing the frame over to
higher layer.
When adding such a DSA master network device as a bridge member, we go
through the following code path when receiving a frame:
__netif_receive_skb_core
-> first ptype check against ptype_all is not returning any
handler for this skb
-> check and invoke rx_handler:
-> deliver frame to the bridge layer: br_handle_frame
DSA registers a ptype handler with the fake ETH_XDSA ethertype, which is
called *after* the bridge-layer rx_handler has run. br_handle_frame()
tries to parse the frame it received from the DSA master network device,
and will not be able to match any of its conditions and jumps straight
at the end of the end of br_handle_frame() and returns
RX_HANDLER_CONSUMED there.
Since we returned RX_HANDLER_CONSUMED, __netif_receive_skb_core() stops
RX processing for this frame and returns NET_RX_SUCCESS, so we never get
a chance to call our switch tag packet processing logic and deliver
frames to the DSA slave network devices, and so we do not get any
functional bridge members at all.
Instead of cluttering the bridge receive path with DSA-specific checks,
and rely on assumptions about how __netif_receive_skb_core() is
processing frames, we simply deny adding the DSA master network device
(conduit interface) as a bridge member, leaving only the slave DSA
network devices to be bridge members, since those will work correctly in
all circumstances.

The logic to configure a network interface for kernel IP
auto-configuration is very simplistic, and does not handle the case
where a device is stacked onto another such as with DSA. This causes the
kernel not to open and configure the master network device in a DSA
switch tree, and therefore slave network devices using this master
network devices as conduit device cannot be open.
This restriction comes from a check in net/dsa/slave.c, which is
basically checking the master netdev flags for IFF_UP and returns
-ENETDOWN if it is not the case.
Automatically bringing-up DSA master network devices allows DSA slave
network devices to be used as valid interfaces for e.g: NFS root booting
by allowing kernel IP autoconfiguration to succeed on these interfaces.
On the reverse path, make sure we do not attempt to close a DSA-enabled
device as this would implicitely prevent the slave DSA network device
from operating.

mii_check_media() does not update the link (carrier) state or log link
changes when the link mode is forced. Drivers using the mii library
must do this themselves, but most of them do not.
Instead of changing them all, provide a sensible default behaviour
similar to mii_check_link() when the mode is forced.
via-rhine depends on it being a no-op in this case, so make its call
to mii_check_media() conditional.

We found a subtle issue with FCoE on T4 very late in the game
and decided not to productize FCoE on T4 and therefore there
are no customers that will be impacted by this change. Hence
T4 FCoE support is removed. FCoE supported only on T5 cards.
changes in v2:
- Make the commit message more clearer.

This patch enhances the NetCP gbe driver to support 10GbE subsystem
available in Keystone NetCP. The 3-port 10GbE switch sub-module contains
the following components:- 10GbE Switch, MDIO Module, 2 PCS-R Modules
(10GBase-R) and 2 SGMII modules (10/100/1000Base-T). The GBE driver
together with netcp core driver provides support for 10G Ethernet
on Keystone SoCs.
10GbE hardware spec is available at

This patch add support for 1G Ethernet driver based on Keystone
NetCP hardware. The gigabit Ethernet (GbE) switch subsystem is one of the main
components of the network coprocessor (NETCP) peripheral. The purpose of the
gigabit Ethernet switch subsystem in the NETCP is to provide an interface to
transfer data between the host device and another connected device in
compliance with the Ethernet protocol. GbE consists of 5 port Ethernet Switch
module, 4 Serial Gigabit Media Independent Interface (SGMII) modules, MDIO
module and SerDes.
Driver for 5 port GbE switch and SGMII module is added in this patch. These
hardware modules along with netcp core driver provides Network driver functions
for 1G Ethernet.
Detailed hardware spec is available at

The network coprocessor (NetCP) is a hardware accelerator available in
Keystone SoCs that processes Ethernet packets. NetCP consists of following
hardware components
1 Gigabit Ethernet (GbE) subsystem with a Ethernet switch sub-module to
send and receive packets.
2 Packet Accelerator (PA) module to perform packet classification
operations such as header matching, and packet modification operations
such as checksum generation.
3 Security Accelerator(SA) capable of performing IPSec operations on
ingress/egress packets.
4 An optional 10 Gigabit Ethernet Subsystem (XGbE) which includes a
3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
per Ethernet port.
5 Packet DMA and Queue Management Subsystem (QMSS) to enqueue and dequeue
packets and DMA the packets between memory and NetCP hardware components
described above.
NetCP core driver make use of the Keystone Navigator driver API to allocate
DMA channel for the Ethenet device and to handle packet queue/de-queue,
Please refer API's in include/linux/soc/ti/knav_dma.h and
drivers/soc/ti/knav_qmss.h for details.
NetCP driver consists of NetCP core driver and at a minimum Gigabit
Ethernet (GBE) module (1) driver to implement the Network device function.
Other modules (2,3) can be optionally added to achieve supported hardware
acceleration function. The initial version of the driver include NetCP
core driver and GBE driver modules.
Please refer Documentation/devicetree/bindings/net/keystone-netcp.txt
for design of the driver.
