net: rtl8169: Fix return value for rtl_send_common

2016-07-06T15:45:11+00:00

Return value of rtl_send_common propogates unmodified all the way
up to eth_send and further to API consumer if CONFIG_API is enabled.
Previously rtl_send_common returned number of bytes sent on success
which was erroneouly detected as error condition by API consumers
that checked for operation success by comparing return value with 0.

Switch rtl_send_common to use common convention: return 0 on success
and negative value for failure.

net: designware: Make driver independent from DM_GPIO again

2016-07-06T15:45:00+00:00

Commit 90b7fc924adf "net: designware: support phy reset device-tree
bindings" made DW GMAC driver dependent on DM_GPIO by unconditional
usage of purely DM_GPIO stuff like:
 * dm_gpio_XXX()
 * gpio_request_by_name()

But since that driver as of today might be easily used without
DM_GPIO (that's the case for Synopsys AXS10x boards) we're
shielding all DM_GPIO things by ifdefs.

net: phy: marvell: Do not reset 88e1310 after autoneg

2016-06-21T22:01:52+00:00

Commit a058052c "net: phy: do not read configuration register on reset",
changes the behaviour of the phy_reset function such that the state of
the BMCR register is not preserved during reset.

Change the config function for the m88e1310 so that it does not do a
reset after configuring auto-negotiation.

net: phy: micrel: add support for KSZ886x switches in MIIM mode

2016-06-21T22:01:52+00:00

This patch adds a phy driver for the Micrel KSZ886x switches.

Similarly to the KSZ8895, SoC MAC is directly connected to the switch
MAC on the switch CPU port, so the link to the switch is always up.

KSZ886x switches can be used in the following configuration modes:
- Unmanaged mode with config stored in external EEPROM
- Managed mode over SPI
- Managed mode over I2C
- Managed mode over mdio/mdc (aka MIIM or SMI)

This patch supports only unmanaged and MIIM modes.

Based on Micrel KSZ886x driver from Linux kernel and
Micrel KSZ8895 driver from U-Boot.

Verified with the KSZ8863MLL.

net: rtl8169: fix switching between adapters

2016-06-21T22:01:51+00:00

The rtl8169 driver uses a global variable to store the register address
of the adapter being operated upon. This is updated to point at the
correct adapter when sending or receiving a packet, or shutting down the
adapter, but not when initializing the adapter. Consequently, switching
between different adapters within the same U-Boot runtime does not work
correctly since the driver programs the wrong registers during
rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start().

Note that since rtl8169_eth_stop() does set the global variable, the
second consecutive attempt to use the "new" adapter did work even before
this patch, because each time network usage is shut down, the network
core calls stop, which sets the variable so that the next start does
actually initialize the hardware, and the adapter works.

Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so
if using only a single device, or if picking the "right" device (based on
probe order) when multiple devices are present, ioaddr will already be set
correctly from the get-go, so the issue does not occur.

Add driver-model support to this driver. The old code remains for now so
that we can convert boards one at a time.

net: macb: Flush correct cache portion when sending

2016-06-12T21:49:38+00:00

The end address of the cache flush must be cache-line-aligned since
otherwise (at least on ARM926-EJS) the request is ignored. When the cache
is enabled this means that packets are not sent.

Adjust this driver to avoid using struct netdev in functions that driver
model will call. Also refactor the receive function to be compatible with
driver model.
