ac1d313806 net: eth: Check return value in various places
eth_get_dev() can return NULL which means device_probe() fails for
that ethernet device. Add return value check in various places or
U-Boot will crash due to NULL pointer access.

With this commit, 'dm_test_eth_act' test case passes.

6d9764c2a8 dm: test: Add a new test case against dm eth codes for NULL pointer access
U-Boot crashes when doing a 'ping' with the following test scenario:

  - All ethernet devices are not probed
  - "ethaddr" for all ethernet devices are not set
  - "ethact" is set to a valid ethernet device name

Add a new test case 'dm_test_eth_act' to hit such scenario.

a16edabe7f net: eth: Clear MAC address in eth_pre_remove()
platdata->enetaddr was assigned to a value in dev_probe() last time.
If we don't clear it, for dev_probe() at the second time, dm eth
will end up treating it as a MAC address from ROM no matter where it
came from originally (maybe env, ROM, or even random). Fix this by
clearing platdata->enetaddr when removing an Ethernet device.

4f485150cf net: phy: micrel: disable NAND-tree for KSZ8051
NAND-tree is used to check wiring between MAC and PHY using NAND gates
on the PHY side, hence the name.

NAND-tree initial status is latched at reset by probing the IRQ pin.
However some devices are sharing the PHY IRQ pin with other peripherals
such as Atmel SAMA5D[34]x-EK boards when using the optional TM7000
display module, therefore they are switching the PHY in NAND-tree test
mode depending on the current IRQ line status at reset.

This patch ensure PHY is not in NAND-tree test mode only for the Micrel
KSZ8051 PHY used by Atmel. There are other Micrel PHY affected but I
doubt they are used on such weird hardware design.

f3ba55235d net: rtl8169: Build warning fixes for 64-bit
Casting from dev->priv to pci_dev_t changes the value's size on a 64-bit
system. This causes the compiler to complain about casting a pointer to an
integer of a different (smaller) size. To avoid this, cast to an integer
of matching size first, then perform an int->int cast to perform the size
change. This signals explicitly that we do want to change the size, and
avoids the compiler warning. This is legitimate since we know the pointer
actually stores a small integer, not a pointer value.

4a4ced0b6f smsc95xx: Use zero length packets when RX fifo is empty
Using NAKs on empty RX fifo for bulk in transfers is the right choice
for a interrupt driven model, but U-Boot uses polling and expects an
immediate answer if there is no incoming packet. Using ZLP Bulk In Response
(BIR) mode avoids unexpected timeouts in the host controller driver.

As ZLP mode is reset default, there is no need to set it.

7ff7166c55 arm: ls102xa: Set fdt_high and initrd_high to the value of 0xffffffff
As 3G/1G user/kernel memory split is used on LS1021A, the Linux kernel
fails to access the device tree blob on boot. The reason is that u-boot
relocates the device tree blob into high memory when booting the kernel
and the kernel is unable to access the blob.

To avoid this issue, fdt_high is set to the value of 0xffffffff. The
device tree blob will not get relocated and is still in low memory to
make it accessible to the kernel.

For the same reason, initrd_high is set to the value of 0xffffffff too.

7aba0f2c2c net/eth: fix a bug in on_ethaddr()
The loop should check all ethenet devices, not only the first device,
to set each specified ethaddr, or it'll cause failure when we use other
devices.

0d2837cc8f smsc95xx: Fetch whole burst with 1 URB, avoid framing errors
smsc95xx_recv() does not reassemble bursts spread over multiple URBs.
If there is a lot of broadcast traffic, the fifo will fill up to the
burst cap limit. Lowering the burst cap to the URB size ensures no packet
spans multiple urbs.
Caveat, lower limit for working burst cap is 5/33 HS/FS packets.
