net: eth_write_hwaddr: Return error for invalid MACs

2012-09-27T17:21:36+00:00

If dev->enetaddr was supposed to be set with dev->write_hwaddr() but the MAC
address was not valid, return an error.

net: Improve the speed of netconsole

2012-09-24T18:55:43+00:00

Previously u-boot would initialize the network interface for every
network operation and then shut it down again.  This makes sense for
most operations where the network in not known to be needed soon after
the operation is complete.  In the case of netconsole, it will use the
network for every interaction with the shell or every printf.  This
means that the network is being reinitialized very often.  On many
devices, this intialization is very slow.

This patch checks for consecutive netconsole actions and leaves the
ethernet hardware initialized between them.  It will still behave the
same old way for all other network operations and any time another
network operation happens between netconsole operations.

api: net: fix length check in eth_receive()

2012-09-24T18:17:24+00:00

If the requested length is too small to hold the received packet,
eth_receive() will return -1 and will leave the packet in the receive
buffers. Instead of returning an error in this case, we return the first
portion of the received packet and remove it from the receive buffers.

This fixes FreeBSD's ubldr. Without this patch it will just stop receiving
packets if the NIC receives more than PKTBUFSRX too large packets.

net: Inline the new eth_setenv_enetaddr_by_index function

2012-07-11T18:15:32+00:00

This function is currently only used in one case.  Inline for now.

net: allow setting env enetaddr from net device setting

2012-07-11T18:15:32+00:00

If the net driver has setup a valid ethernet address and an ethernet
address is not set in the environment already, then set the environment
variables from the net driver setting.

This enables pxe booting on boards which don't set ethaddr env variable.

net: add helper to generate random mac address

2012-07-07T12:07:32+00:00

net: move bootfile init into eth_initialize

2012-05-15T22:32:33+00:00

All arches init this the same way, so move the logic into the core
net code to avoid duplicating it everywhere else.

net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back

2012-04-04T00:25:45+00:00

Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
fails, fall back to use dev->enetaddr, which could be filled up by
the ethernet device driver:

With the current code, introduced with below commit, eth_write_hwaddr()
will fail immediately if there is no ethaddr in the environment variables.

However, e.g. for an overo based product that uses the SMSC911x ethernet
chip (with the MAC address set via EEPROM connected to the SMSC911x chip),
the MAC address is still OK.

On mx28 boards that are depending on the OCOTP bits to set the MAC address
(like the Denx m28 board), the OCOTP bits should be used instead of
failing on the environment variables.

Actually, this was the original behavior, and was later changed by
commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.
