Currently netcp_module_probe() doesn't check the return value of
of_parse_phandle() that points to the interface data for the
module and then pass the node ptr to the module which is incorrect.

in the rx free descriptor queue, inside the netcp_rxpool_refill() function

The netcp interface is not fully initialized before attach the module
to the interface. For example, the tx pipe/rx pipe is initialized
in ethss module as part of attach(). So until this is complete, the
interface can't be registered. So move registration of interface to
net device outside the current loop that attaches the modules to the
interface.

netcp_core is the first driver that will get initialized and the modules
(ethss, pa etc) will then get initialized. So the code at the end of

On K2HK, sgmii module registers of slave 0 and 1 are mem
mapped to one contiguous block, while those of slave 2
and 3 are mapped to another contiguous block. However,
on K2E and K2L, sgmii module registers of all slaves are
mem mapped to one contiguous block. SGMII APIs expect
slave 0 sgmii base when API is invoked for slave 0 and 1,
and slave 2 sgmii base when invoked for other slaves.
Before this patch, slave 0 sgmii base is always passed to
sgmii API for K2E regardless which slave is the API invoked
for. This patch fixes the problem.

Commit 54d792f257 ("net: dsa: Centralise global and port setup
code into mv88e6xxx.") merged in the 4.2 merge window broke the link
speed forcing for the CPU port of Marvell DSA switches. The original
code was:
/* MAC Forcing register: don't force link, speed, duplex
* or flow control state to any particular values on physical
* ports, but force the CPU port and all DSA ports to 1000 Mb/s
* full duplex.
*/
if (dsa_is_cpu_port(ds, p) || ds->dsa_port_mask & (1 << p))
REG_WRITE(addr, 0x01, 0x003e);
else
REG_WRITE(addr, 0x01, 0x0003);
but the new code does a read-modify-write:
reg = _mv88e6xxx_reg_read(ds, REG_PORT(port), PORT_PCS_CTRL);
if (dsa_is_cpu_port(ds, port) ||
ds->dsa_port_mask & (1 << port)) {
reg |= PORT_PCS_CTRL_FORCE_LINK |
PORT_PCS_CTRL_LINK_UP |
PORT_PCS_CTRL_DUPLEX_FULL |
PORT_PCS_CTRL_FORCE_DUPLEX;
if (mv88e6xxx_6065_family(ds))
reg |= PORT_PCS_CTRL_100;
else
reg |= PORT_PCS_CTRL_1000;
The link speed in the PCS control register is a two bit field. Forcing
the link speed in this way doesn't ensure that the bit field is set to
the correct value - on the hardware I have here, the speed bitfield
remains set to 0x03, resulting in the speed not being forced to gigabit.
We must clear both bits before forcing the link speed.

There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
vendor driver supports the CH9100 and CH9200 devices, but the majority of
the code is of the if (ch9100) {} else {} form, with the most significant
difference being that CH9200 provides a real MII interface but CH9100 fakes
one with a bunch of global variables and magic commands. I don't have a
CH9100, so it's probably better if someone who does provides an independent
driver for it. In any case, this is a lightly cleaned up version of the
vendor driver with all the CH9100 code dropped.

commit c48f350ff5 "bnx2x: Add MFW dump support" added the
bnx2x_update_mfw_dump() function that reads the current time and stores
it in a 32-bit field that gets passed into a buffer in a fixed format.
This is potentially broken when the epoch overflows in 2038, and
otherwise overflows in 2106. As we're trying to avoid uses of
struct timeval for this reason, I noticed the addition of this
function, and tried to rewrite it in a way that is more explicit
about the overflow and that will keep working once we deprecate
struct timeval.
I assume that it is not possible to change the ABI any more, otherwise
we should try to use a 64-bit field for the seconds right away.

There exist one issue by below case that case system hang:
ifconfig eth0 down
ifconfig eth0 hw ether 00:10:19:19:81:19
After eth0 down, all fec clocks are gated off. In the .fec_set_mac_address()
function, it will set new MAC address to registers, which causes system hang.
So it needs to add netif status check to avoid registers access when clocks are
gated off. Until eth0 up the new MAC address are wrote into related registers.
