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: Remove static allocation for MAC address in PingSend()

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

Don't force ARP clients to return the MAC address if they don't care
(such as ping)

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 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

2012-05-23T22:46:19+00:00

Save the length when it is computed instead of forgetting it and
subtracting pointers to figure it out again.

net: Refactor IP, UPD, and ICMP header writing functions

2012-05-23T22:46:18+00:00

ICMP (ping) was reimplementing IP header code... it now shares code.
