* Nice Update of PPPD support which eliminates the requiremetn that drivers be in the termios TASK_DRIVEN mode. Mike did significant testing and reports that it seems to be more stable and handle larger packets better. This patch replaces the termios tasks with more general pppd network driver tasks. The functions pppinput() and pppstart() get called from the interrupt service routine. * Makefile.am, configure.ac, net/Makefile.am, net/bpf.h, net/ethernet.h, net/if.c, net/if.h, net/if_arp.h, net/if_dl.h, net/if_ethersubr.c, net/if_llc.h, net/if_loop.c, net/if_ppp.h, net/if_pppvar.h, net/if_types.h, net/netisr.h, net/ppp-comp.h, net/ppp_defs.h, net/pppcompress.h, net/radix.c, net/radix.h, net/raw_cb.c, net/raw_cb.h, net/raw_usrreq.c, net/route.c, net/route.h, net/rtsock.c, pppd/Makefile.am, pppd/README, pppd/STATUS, pppd/auth.c, pppd/cbcp.c, pppd/ccp.c, pppd/ccp.h, pppd/chap.c, pppd/chap.h, pppd/chap_ms.c, pppd/chap_ms.h, pppd/chat.c, pppd/demand.c, pppd/fsm.c, pppd/fsm.h, pppd/ipcp.c, pppd/ipcp.h, pppd/ipxcp.c, pppd/ipxcp.h, pppd/lcp.c, pppd/lcp.h, pppd/magic.c, pppd/magic.h, pppd/options.c, pppd/patchlevel.h, pppd/pathnames.h, pppd/pppd.8, pppd/pppd.h, pppd/rtemsmain.c, pppd/rtemspppd.c, pppd/rtemspppd.h, pppd/sys-rtems.c, pppd/upap.c, pppd/upap.h, pppd/utils.c, pppd/example/README, pppd/example/netconfig.h, wrapup/Makefile.am: Modified. * net/bsd-comp.c, net/if_ppp.c, net/ppp-deflate.c, net/ppp.h, net/ppp_tty.c, net/pppcompress.c, net/zlib.c, net/zlib.h: New file. * modem/, modem/.cvsignore, modem/Makefile.am, modem/ppp.c, modem/ppp.h, modem/ppp_tty.c, modem/pppcompress.c: Subdirectory removed.
