From e16967941bceae40449cf56f822420a7088bd08a Mon Sep 17 00:00:00 2001 From: Nikos Nikoleris Date: Mon, 5 Dec 2016 16:48:21 -0500 Subject: [PATCH] mem: Make packet debug printing more uniform Previously DPRINTFs printing information about a packet would use ad hoc formats. This patch changes all DPRINTFs to use the print function defined by the packet class, making the packet printing format more uniform and easier to change.
