net: add a define for the number of packets received as batch

2020-10-19T20:59:53+00:00

With a define for the magic number of packets received as batch
we can make sure that the EFI network stack caches the same amount
of packets.

net: Expose some errors generated in net_init

2020-10-10T20:50:12+00:00

net_init does not always succeed, and there is no existing mechanism to
discover errors. This patch allows callers of net_init (such as net_init)
to handle errors. The root issue is that eth_get_dev can fail, but
net_init_loop doesn't expose that. The ideal way to fix eth_get_dev would
be to return an error with ERR_PTR, but there are a lot of callers, and all
of them just check if it's NULL. Another approach would be to change the
signature to something like

int eth_get_dev(struct udevice **pdev)

but that would require rewriting all of the many callers.

net: use log_err() for 'No ethernet found' message

2020-09-30T20:48:18+00:00

Write the 'No ethernet found' message via the log drivers. This allows
suppressing it during output via the syslog driver.

This fixes the problem reported in:

net: dm: Remove warning about EEPROM provided MAC address

2020-07-07T22:23:48+00:00

Similar to patch 821fec0ceb3e ("net: remove scary warning about EEPROM
provided MAC address") this removes the somewhat awkward "warning" on
boards using DM_ETH:
In many parts of the computing world having a unique MAC address
sitting in some on-NIC storage is considered the normal case.

If there is a properly provided MAC address (either from ROM or from DT),
remove the warning to not scare the user unnecessarily.

net: Add eth phy generic driver for shared MDIO

2020-05-10T11:24:48+00:00

For dual ethernet controllers, the HW design may connect ETH phys to
one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.

To resolve this problem, introduce an eth phy generic driver and uclass.

After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.

When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.

net: eth-uclass: ignore unavailable devices

2019-12-09T15:47:42+00:00

device_probe() may fail in which case the seq_id will be -1. Don't
display these devices during startup. While this is only a cosmetic
change, the return value of eth_initialize() will also change to the
actual number of available devices. The return value is only used in
spl_net to decide whether there are any devices to boot from. So
returning only available devices is also more correct in that case.
