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()).Signed-off-by: Joe Hershberger

NFS_TIMEOUT is constant value defined in net/nfs.c. But sometimes it needs to adjust.
This patch enables to override NFS_TIMEOUT by defining CONFIG_NFS_TIMEOUT in a board specific config file.Signed-off-by: Tetsuyuki Kobayashi

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.

The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.Signed-off-by: Jayachandran Chandrasekharan Nair

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 changesSigned-off-by: Joe Hershberger

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.Signed-off-by: Joe Hershberger
