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().

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

net: Refactor to protect access to the NetState variable

2012-05-23T22:46:21+00:00

Changes to NetState now go through an accessor function called
net_set_state()

net: Refactor to use NetSendPacket instead of eth_send directly

2012-05-23T22:46:20+00:00

Use this entry-point consistently across the net/ code
Use a static inline function to preserve code size
