	Thank you very much!  I'll be visiting IETF so I love to use this
	driver!
	To use IPv6 on top of this card, I think:
	- the following patch (for using mbuf cluster), and
	- some code to handle SIO[CD]ADDMULTI (multicast is mandatory on IPv6)
	are necessary .  I don't have the card myself at this moment
	so I couldn't test it.  I'll be able to hack and test it during IETF.
