The DSA sandbox driver is used for unit testing the DSA class code.
It implements a simple 2 port switch plus 1 CPU port, and uses a
very simple tag to identify the ports.
The DSA sandbox device is connected via CPU port to a regular Ethernet
sandbox device, called 'dsa-test-eth, managed by the existing eth
sandbox driver. The 'dsa-test-eth' is not intended for testing the
eth class code however, but it is used to emulate traffic through the
'lan0' and 'lan1' front pannel switch ports. To achieve this the dsa
sandbox driver registers a tx handler for the 'dsa-test-eth' device.
The switch ports, labeled as 'lan0' and 'lan1', are also registered
as eth devices by the dsa class code this time. So pinging through
these switch ports is as easy as:
=> setenv ethact lan0
=> ping 1.2.3.5
Unit tests for the dsa class code were also added. The 'dsa_probe'
test exercises most API functions from dsa.h. The 'dsa' unit test
simply exercises ARP/ICMP traffic through the two switch ports,
including tag injection and extraction, with the help of the dsa
sandbox driver.
I took care to minimize the impact on the existing eth unit tests,
though some adjustments needed to be made with the addition of
extra eth interfaces used by the dsa unit tests. The additional eth
interfaces also require MAC addresses, these have been added to the
sandbox default environment.

On systems that use CONFIG_OF_LIVE, the "ofnode" type is defined
as const struct device_node *np, while on the flat DT systems it
is defined as a long of_offset into gd->fdt_blob.
It is desirable that the fixed PHY driver uses the higher-level
ofnode abstraction instead of parsing gd->fdt_blob directly,
because that enables it to work on live OF systems.
The fixed PHY driver has used a nasty hack since its introduction in
commit db40c1aa1c ("drivers/net/phy: add fixed-phy /
fixed-link support"),
which is to pass the long gd->fdt_blob offset inside int phydev->addr
(a value that normally holds the MDIO bus address at which the PHY
responds). Even ignoring the fact that the types were already
mismatched leading to a potential truncation (flat OF offset was
supposed to be a long and not an int), we really cannot extend this
hack any longer, because there's no way an int will hold the other
representation of ofnode, the struct device_node *np.
So we unfortunately need to do the right thing, which is to use the
framework introduced by Grygorii Strashko in
commit eef0b8a930 ("net: phy: add ofnode node to struct phy_device").
This will populate phydev->node for the fixed PHY.
Note that phydev->node will not be valid in the probe function, since
that is called synchronously from phy_device_create and we really have
no way of passing the ofnode directly through the phy_device_create API.
So we do what other drivers do too: we move the OF parsing logic from
the .probe to the .config method of the PHY driver. The new function
will be called at phy_config() time.
I do believe I've converted all the possible call paths for creating
a PHY with PHY_FIXED_ID, so there is really no reason to maintain
compatibility with the old logic of retrieving a flat OF tree offset
from phydev->addr. We just pass 0 to phydev->addr now.

The phy-handle is specified as a path rather than a label because it is
possible to use the #include multiple times (meaning that more than one

duplicate labels with the same name.

bar

=> setenv foo 'echo bar ; exit 0' ; run foo ; echo $?
bar
0
=> setenv foo 'echo bar ; exit -2' ; run foo ; echo $?

That is, no matter what the 'exit' command argument is, the return
value is always 0 and so it is not possible to use script return
value in subsequent tests.
Fix this and simplify the exit command such that if exit is called with
no argument, the command returns 0, just like 'true' in cmd/test.c. In
case the command is called with any argument that is positive integer,
the argument is set as return value.

Fortunately, the guys at OpenBSD came up with strl(cat|cpy), which always
