Log:
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.
