From a69553be4250a8a40d603d8f3123ec532d5fb390 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Wed, 14 Aug 2013 16:26:05 -0700 Subject: [PATCH] ofproto: Remove obsolete comment and assertion. At one time, the ofproto-dpif implementation of the 'rule_execute' member function required, indirectly, at least struct(ofp10_packet_in) bytes of headroom in the packet passed into it. (This allowed constructing an OFPT_PACKET_IN without allocating and copying a new ofpbuf.) This restriction has long been lifted, but rule_execute() had not yet caught up. This commit updates it.
