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.

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.

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

net: bootp: Ignore packets whose yiaddr is 0

2016-01-28T18:22:23+00:00

When doing `dhcp`, there is a bad dhcp server in my network
which always reply dhcp request with yiaddr 0, which cause
uboot can not successfully get ipaddr from the good dhcp server.
But the Linux PC can get the ip address even if there is a bad
dhcp server. This patch is to fix that even if there is a bad
dhcp server, uboot can still get ipaddr and tftp work ok.

The way is to ignore the packets from the bad dhcp server by filtering
out the yiaddr whose value is 0.
