Just to keep the issue open, drivers/net/ipg.c currently in 2.6.24-rc6
still leaks skbuffs like a sieve.  Run it for a few hours with network
traffic and the machine swaps like crazy while the oom killer goes nuts.

 	---help---
 	  This driver supports IP1000 gigabit Ethernet cards.
+	  It works, but suffers from a memory leak.  Signifcant
+	  use will consume unswappable kernel memory until the
+	  machine runs out of memory and crashes.  Thus, this
+	  driver cannot be considered usable at the the present time.
 
 	  To compile this driver as a module, choose M here: the module
 	  will be called ipg.  This is recommended.

Or should it be demoted to BROKEN?  It compiles, and sends and receives
packets, which is better than a lot of BROKEN drivers.
