From 9daec60824d085db8c2f841fd389c725df1f8b0b Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Thu, 30 Nov 2017 21:26:51 +0000 Subject: Cleanup XFA packet code Remove GetPacketByID, move GetPacketByName to the xfa_utils file. Cleanup CreateNode to accept the XFA_XDPPACKET instead of the packet info.
