From d1cc5b22d78b6226d2469a4044e415f618ab894a Mon Sep 17 00:00:00 2001 From: andre Date: Thu, 2 Nov 2006 17:37:22 +0000 Subject: Rename m_getm() to m_getm2() and rewrite it to allocate up to page sized mbuf clusters. Add a flags parameter to accept M_PKTHDR and M_EOR mbuf chain flags. Provide compatibility macro for m_getm() calling m_getm2() with M_PKTHDR set. Rewrite m_uiotombuf() to use m_getm2() for mbuf allocation and do the uiomove() in a tight loop over the mbuf chain. Add a flags parameter to accept mbuf flags to be passed to m_getm2(). Adjust all callers for the extra parameter.
