f739fcd831 SPDX: Convert a few files that were missed before
As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

Fixes: 83d290c56f ("SPDX: Convert all of our single license tags to Linux Kernel style")

049a95a775 net: cosmetic: Change IPaddr_t to struct in_addr
This patch is simply clean-up to make the IPv4 type that is used match
what Linux uses. It also attempts to move all variables that are IP
addresses use good naming instead of CamelCase. No functional change.

2ea9103924 SPDX License cleanup for LiMon imported files
A number of network related files were imported from the LiMon
project; these contain a somewhat unclear license statement:

	Copyright 1994 - 2000 Neil Russell.
	(See License)

I analyzed the source code of LiMon v1.4.2 which was used for this
import.  It does not contain any "License" file, but the top level
directory contains a file "COPYING", which turns out to be GPL v2
of June 1991.  So it is legitimate to conclude that the LiMon derived
files are also to be released under GPLv2.  Mark them as such.

4ef8d53caa net: Allow filtering on debug traces in the net subsystem
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

e94070c443 net: Don't copy every packet that waits for an ARP
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.
