From 567ac2b268739a751df819d1aa68404f430151cb Mon Sep 17 00:00:00 2001 From: des Date: Tue, 8 Apr 2003 14:25:47 +0000 Subject: Introduce an M_ASSERTPKTHDR() macro which performs the very common task of asserting that an mbuf has a packet header. Use it instead of hand- rolled versions wherever applicable.
