sys/net if_tap.c if_tun.c ppp_tty.c
sys/netgraph ng_device.c
sys/sys mbuf.h
Log:
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.
