Work around some nasty bugs on the [beta] Itanium2's E1000 UNDI driver.

Bug#1: The GetStatus() function returns radically different pointers that
do not match any packets we transmitted.  I think it might be pointing to
a copy of the packet or something.  Since we do not transmit more than
one packet at a time, just wait for "anything".

Bug#2: The Receive() function takes a pointer and a length.  However, it
either ignores the length or otherwise does bad things and writes outside
of ptr[0] through ptr[len-1].  This is bad and causes massive stack
corruption for us since we are receiving packets into small buffers on
the stack.  Instead, Receive() into a large enough buffer and bcopy the
data to the requested area.
