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: fix typo in arp clean up

2012-07-10T15:14:56+00:00

The clean up patch missed an &, so we end up passing an int rather than
a pointer to the sprintf function.

arp.c: In function 'ArpReceive':
arp.c:197: warning: format '%p' expects type 'void *', but argument 3 has type 'int'

net: make net_rand.h inclusion depend on BOOTP_RANDOM_DELAY

2012-07-08T20:39:42+00:00

commit "net: use common rand()/srand() functions" introduced the following
build warning on the current u-boot-arm tree:

$ ./MAKEALL MPC8313ERDB_66
Configuring for MPC8313ERDB_66 - Board: MPC8313ERDB, Options: SYS_66MHZ

In file included from bootp.c:15:0:
net_rand.h: In function 'srand_mac':
net_rand.h:40:2: warning: implicit declaration of function 'srand' [-Wimplicit-function-declaration]

adding this dependency fixes it.

net: use common rand()/srand() functions

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

Replace rand() with the functions from lib/. The link-local network code
stores its own seed, derived from the MAC address. Thus making it
independent from calls to srand() in other modules.

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: Work-around for brain-damaged Cisco equipment with arp-proxy

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

Cisco's arp-proxy feature fails to ignore the link-local address range
This means that a link-local device on a network with this Cisco
equipment will reply to ARP requests for our device (in addition to
our reply).
If we happen to reply first, the requester's ARP table will be
populated with our MAC address, and one packet will be sent to us...
shortly following this, the requester will get an ARP reply from the
Cisco equipment telling the requester to send packets their way
instead of to our device from now on.
This work-around detects this link-local condition and will delay
replying to the ARP request for 5ms so that the first packet is sent
to the Cisco equipment and all following packets are sent to our
device.
