ldpaa_eth.c: Fix warning when PHYLIB is not enabled

2018-10-12T11:41:24+00:00

We need to #ifdef some variables to avoid warning about them being
unused.

driver: net: fsl-mc: Add support of multiple phys for dpmac

2018-10-10T17:45:28+00:00

Till now we have had cases where we had one phy device per dpmac.
Now, with the upcoming products (LX2160AQDS), we have cases, where there
are sometimes two phy devices for one dpmac. One phy for TX lanes and
one phy for RX lanes. to handle such cases, add the support for multiple
phys in ethernet driver. The ethernet link is up if all the phy devices
connected to one dpmac report link up. also the link capabilities are
limited by the weakest phy device.

i.e. say if there are two phys for one dpmac. one operates at 10G without
autoneg and other operate at 1G with autoneg. Then the ethernet interface
will operate at 1G without autoneg.

driver: net: fsl-mc: initialize dpmac irrespective of phy

2018-10-10T17:45:23+00:00

The dpmac initalization should not depend on phy.
As the phy is not necessary to be present for dpmac to function.
Therefore, remove dpmac initialization dependency from phy.

driver: net: fsl-mc: Modify the dpmac link detection method

2018-10-10T17:45:01+00:00

when there is no phy present for a dpmac, a dummy phy device is created.
when we move to multiple phy method, we need to create as many dummy phy
devices.

Change this method so that we don't need to create dummy phy devices.
We always report linkup if no phy is present.

driver: net: fsl-mc: fix error handing in init_phy

2018-10-10T17:43:18+00:00

if an error occurs during init_phy, we should free the phydev structure
which has been allocated by phy_connect.

driver: net: fsl-mc: remove unused strcture elements

2018-10-10T17:36:34+00:00

The phydev structure is present in both ldpaa_eth_priv and
wriop_dpmac_info. the phydev in wriop_dpmac_info is not being used

As the phydev is created based on phy_addr and bus members of
wriop_dpmac_info, it is appropriate to keep phydev in wriop_dpmac_info.

Also phy_regs is not being used, therefore remove it

test: eth: Add a test for the target being pinged

2018-10-10T17:29:00+00:00

The target will respond to pings while doing other network handling.
Make sure that the response happens and is correct.

This currently corrupts the ongoing operation of the device if it
happens to be awaiting an ARP reply of its own to whatever serverip it
is attempting to communicate with. In the test, add an expectation that
the user operation (ping, in this case) will fail. A later patch will
address this problem.

net: sandbox: Add a priv ptr for tests to use

2018-10-10T17:28:59+00:00

Tests need to be able to pass their "unit test state" to the handlers
where asserts are evaluated. Add a function that allows the tests to set
this private data on the sandbox eth device.
