Note: in the ping.c fix, commit a36b12f95a29647a06b5459198684fc142482020
"net: Move PING out of net.c" mistakenly carried the ifdef CMD_PING
clause from when it was necessary to avoid warnings when it was embedded
in net.c.

net: Filter incoming netconsole packets by IP

2012-09-24T18:55:44+00:00

Check the incoming packets' source IP address... if ncip isn't set to a
broadcast address, only listen to the client at ncip.

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.

ethernet address.

net: Allow filtering on debug traces in the net subsystem

2012-05-23T22:53:08+00:00

Add several levels of DEBUG prints so that you can limit the noise to
the severety of your problem.

DEBUG_LL_STATE = Link local state machine changes
DEBUG_DEV_PKT = Packets or info directed to the device
DEBUG_NET_PKT = Packets on info on the network at large
DEBUG_INT_STATE = Internal network state changes

net: Don't copy every packet that waits for an ARP

2012-05-23T22:53:07+00:00

Use the NetArpTxPacket for the ARP packet, not to hold what used to
be in NetTxPacket.
This saves a copy and makes the code easier to understand.

net: Fix net buffer initialization

2012-05-23T22:53:06+00:00

A new non-static function net_init() will initialize buffers and
read from the environment.  Only update from the env on each entry
to NetLoop().

net: Add net_update_ether() to handle ARP and Ping replies

2012-05-23T22:53:04+00:00

When the network is VLAN or SNAP, net_update_ether() will preserve
the original Ethernet packet header and simply replace the src and
dest MACs and the protocol

net: Refactor to separate the UDP handler from the ARP handler

2012-05-23T22:52:53+00:00

Call a built-in dummy if none is registered... don't require
protocols to register a handler (eliminating dummies)
NetConsole now uses the ARP handler when waiting on arp
(instead of needing a #define hack in arp.c)
Clear handlers at the end of net loop
