Maximum size for sk_buff?

[RogersWilliamJ@xxxxxxx]

I am writing a network device driver and would like to pre-allocate receiving 
sk_buff's to save time.  In order to do this, I would like to allocate 
maximum sized sk_buff's.

Does sk_buff have a maximum size?  If so, what is it and is there a reference?

Thank you.
