-  Title:       INTERRUPT LEVEL PROCESSING IN ETHERNET DRIVERS
-  Description: Too many Ethernet drivers do interrupt-level processing with
-               the network stack.  The network stack supports either interrupt
-               level processing or normal task level processing (depending on
-               CONFIG_NET_NOINTS).  This is really a very bad use of CPU
-               resources;  All of the network stack processing should be
-               modified to use a work queue (and, all use of CONFIG_NET_NOINTS=n
-               should be eliminated).  This applies to many Ethernet drivers:

+  Title:       IPv6 REQUIRES ADDRESS FILTER SUPPORT
+  Description: IPv6 requires that the Ethernet driver support NuttX address
+               filter interfaces.  Several Ethernet drivers do support there,
+               however.  Others support the address filtering interfaces but
+               have never been verifed:
+
+               C5471, LM3X, ez80, DM0x90 NIC, PIC: Do not support address
+                 filteringing.
+               Kinetis, LPC17xx, LPC43xx:  Untested address filter support
+
+  Status:      Open
+  Priority:    Pretty high if you want a to use IPv6 on these platforms.
