+The following parameters should be tunable but aren't, until we get sysctl
+or similar schemes. For now you'll have to dig around. Various CONFIG_xxx
+items that should be configurable using sysctl omitted.
+
+This is far from complete
+
+Item			Description

+AX25_DEF_BACKOFF	'E'xponential 'L'inear
+AX25_DEF_NETROM		Allow netrom 1=Y
+AX25_DF_TEXT		Allow PID=Text 1=Y
+AX25_DEF_WINDOW		Window for normal mode
+AX25_DEF_EWINDOW	Window for PE1CHL mode

+			cache align and faster forwarding (tunable)
+IPFRAG_HIGH_THRESH	Limit on fragments, we free fragments until we reach
+IPFRAG_LOW_THRESH	which provides some breathing space. (tunable)
+IP_FRAG_TIME		Time we hold a fragment for. (tunable)

+NetROM parameters are tunable via an ioctl passing a struct
+
+4000			Size a Unix domain socket malloc falls back to 
+			(tunable) should be 8K - a bit for 8K machines like
