bootp: Prevent u-boot from using others responses.

2016-03-27T13:12:21+00:00

In rare circumstances two dhcp clients may generate the same
bootp ID. If this happens it is vital that the client also checks
the hw address in the received response to prevent IP address conflicts.

net: bootp: Add environment variable for timeout period

2016-02-26T19:37:38+00:00

There is currently one config option (CONFIG_NET_RETRY_COUNT) that
is available to tune the retries of the network stack.
Unfortunately, it is global to all protocols, and the value is
interpreted differently in all of them.

Add a new environment variable that directly sets the retry period for
BOOTP timeouts. If this new value is not set, the period is still derived
from the default number of retries, or from CONFIG_NET_RETRY_COUNT if
defined. When both the new variable is set and CONFIG_NET_RETRY_COUNT
is defined, the variable has precedence.

net: Add bootfile in DHCP Request

2016-01-28T23:19:43+00:00

Add the bootfile name in the DHCP Request packet, in addition
to it already being sent in the DHCP Discover.

This is needed by some DHCP servers so that the bootfile name is
properly returned by the server to the client in the DHCP Ack, as
expected by U-Boot.

net: Rename eth.c to eth_lecacy.c

2016-01-28T18:32:48+00:00

Rename this file to make it clear it is for the old networking drivers
and not for use with driver model.

net: Move driver-model code into its own file

2016-01-28T18:32:47+00:00

Every other uclass is in its own file. Create a new eth-uclass.c file and
move the driver-model code into it, so that networking is consistent.

Only half of the init is actually common. Move that part into a new common

will be added in future patches.

net: Don't call board/cpu_eth_init() with driver model

2016-01-28T18:32:45+00:00

We should avoid weak functions with driver model. Existing boards that use
driver model don't need them, so let's kill them off.
