Date:	Fri, 13 Mar 2009 17:52:03 -0700
From:	Dhananjay Phadke <dhananjay@...xen.com>

Cc:	davem@...emloft.net
Subject: [patch next 3/6] netxen: sanitize variable names

o remove max_ prefix from ring sizes, since they don't really
  represent max possible sizes.
o cleanup naming of rx ring types (normal, jumbo, lro).
o simplify logic to choose rx ring size, gig ports get half
  rx ring of 10 gig ports.
