Added ka9q tcpip stack and network driver for the gen68360. This effort

was done based on the 3.6.0 release and had to be autoconf'ed locally.
It is turned on is the bsp enables it and it is not explicitly disabled
via the configure option --disable-tcpip.   As many warnings as possible
were removed locally after the code was merged.  Only the gen68360
and mvme136 bsps were compiled this way.

The ka9q port and network driver were submitted by Eric Norum
(eric@skatter.USask.Ca).

The network demo programs are not included in the tree at this point.

+# This board support package works with several different versions of

+# phase by setting the Makefile LDFLAGS definition appropriately.
+#
+# Decisions to be made a link-edit time include:
+#	- The version of hardware on which the application is to run.
+#	  This is selected by defining the MC68360HardwareType variable.
+#	  Supported values are:
+#			MC68360HardwareTypeMotorolaGeneric (default)
+#			MC68360HardwareTypeAtlasHSB
+#	  To select the Atlas Computer Equipment HSB,

+#
+#	- The amount of dynamic RAM in the system.  This value applies
+#	  only to hardware versions which support different sizes of RAM.
+#	  The default value is 4 Mbytes.  To specify 16 Mbytes of memory,
+#		--defsym RamSize=0x1000000
+#
+#	- The size of the memory allocator heap.  The default value is
+#	  64 kbytes.  If the KA9Q network package is used the heap
+#	  should be at least 256 kbytes.  If your network is large, or
+#	  busy, the heap should be even larger.
