With this, modules below ip can +be inserted, or removed, without having the ip stream be unplumbed, and re- +plumbed again. All states in ip for an interface will therefore now be +preserved. Users can install (or upgrade) modules like firewall, bandwidth +manager, cache manager, tunneling, etc., without shutting the machine down. + +To support this, ppp driver now uses /dev/udp instead of /dev/ip for +the ip stream. The interface stream (where ip module pushed on top of ppp) +is then I_PLINK'ed below the ip stream. /dev/udp is used because STREAMS will +not let a driver be PLINK'ed under itself, and /dev/ip is typically the driver +at the bottom of the tunneling interfaces stream. The mux ids of the ip +streams are then added using SIOCSxIFMUXID ioctl. + +Users will be able to see the modules on the insterface stream by, for example: + + pikapon% ifconfig ppp modlist + 0 ip + 1 ppp + +Or arbitrarily if bandiwth manager and firewall modules are installed: + + pikapon% ifconfig hme0 modlist + 0 arp + 1 ip + 2 ipqos + 3 firewall + 4 hme + +Snoop Support. +************** + +This version includes support for /usr/sbin/snoop.

Once done, the quickest way +to get IPv6 running is to add the following somewhere in the command line +option: + + +ipv6 ipv6cp-use-persistent + +The persistent id for the link-local address was added to conform to RFC 2472; +such that if there's an EUI-48 available, use that to make up the EUI-64. As of +now, the Solaris implementation extracts the EUI-48 id from the Ethernet's MAC +address (the ethernet interface needs to be up). Future works might support +other ways of obtaining a unique yet persistent id, such as EEPROM serial +numbers, etc. + +There need not be any up/down scripts for ipv6, e.g. /etc/ppp/ipv6-up or +/etc/ppp/ipv6-down, to trigger IPv6 neighbor discovery for auto configuration +and routing. The in.ndpd daemon will perform all of the necessary jobs in the +background. /etc/inet/ndpd.conf can be further customized to enable the machine +as an IPv6 router.

This +may be due to bugs in pppd itself, bugs in Solaris or the serial drivers. +The /dev/zsh driver seems more larger and can send/receive larger frames +than the /dev/se_hdlc driver. There is a confirmed bug with NRZ/NRZI mode +in the /dev/se_hdlc driver, and Solaris patch 104596-11 is needed to correct +it. (However this patch seems to introduce other serial problems.
