net: fix netconsole filtering

2012-10-03T23:01:22+00:00

Adjustment of Michael Walle's fix patch

Commit 8a0eccb1056b313b45ab62e3aac400f339aa71b4 breaks netconsole. src_ip
must not be converted to host byte order, because nc_ip is already stored
in network byte order (see string_to_ip(), called by getenv_IPaddr()).

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.

net: bugfix: NetSetTimeout assumes CONFIG_SYS_HZ=1000

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

NetSetTimeout sets incorrect value to timeDelta when CONFIG_SYS_HZ != 1000.

net: Make sure the ethaddr is updated in net_init()

2012-07-24T19:09:40+00:00

NetConsole may call NetSendUDPPacket before NetLoop is called.  This
will cause the source MAC address (NetOurEther) to be wrong.  Instead
of only changing it in NetLoop, move it to NetLoopInit so that it is
also updated when net_init() is called (especially by nc_start()).

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().
