on the local network support them.
This adds a new socket option, SO_JUMBO, and a new route flag,
RTF_JUMBO. If _both_ the socket option is set and the route for the host
has RTF_JUMBO set, ip_output will fragment the packet to the largest
possible size for the link, ignoring the card's MTU.
The semantics of this feature will be evolving rapidly; talk to us
if you intend to use it.

carpdev case; block outgoing packets in carp_output() instead.
- unbreak the "bow out on 'ifconfig down'" behaviour, allows instant
failover on graceful halt/reboot to work again.

1. set rcv_laststart/rcv_lastend after checking the tcp window
2. pass rcv_laststart and rcv_lastend on the stack (shrink tcp state)

It's neither supported nor needed, since we have carpdev now.

ensures that only one carp host will reply to a given arp request.

while t_rtt was 1-based), update callers
2. define and use TCP_RTT_BASE_SHIFT instead of the hardcoded 2.
3. add missing shifts when t_srtt/t_rttvar are used.
4. update the comments: t_srtt uses 5 bits of fraction (not 3)
and t_rttvar uses 4 bits
5. remove obsolete/unused macros TCP_RTT_SCALE and TCP_RTTVAR_SCALE
6. make sure rttmin is not > TCPTV_REXMTMAX

Advertisements run through the carp interface first.
So we just take the address from ifp0.
While we're there,
also remove carp_macmatch6, which isn't used anymore.

not addressed to the machine. If the destination is not a local address do a
route lookup for the original source address and use the returned interface
address. This solves problems seen on interfaces with multiple networks
defined. OK henning@ markus@

- Keep track of allhost multicast address record we joined into
each in_ifaddr and delete it when an address is purged.
- Don't simply try to delete a multicast address record listed in the
ia_multiaddrs. It results a dangling pointer. Let whoever holds a
reference to it to delete it.

- Ignore ts_ecr if it is 0, or the resulting rtt is out of range.
(use tp->t_rtttime instead)
- Initialise tcp_now to 1, to avoid the 500ms window where a valid ts_ecr
of 0 could be ignored.
- Convert out-of-range rtt values to valid ones in tcp_xmit_timer().
