Reorder code to not depend on an ISO-C illegal forward extern declaration.
----------------------------
Reason: do not move large functions location without serious reason. The same
could be done by forward function declaration. Please do not enlarge diff
without a reason any more.

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.
Reason: bad previous commit. Would be restored by next commit.
flag on IP packets. Currently this option is only repected on udp
and raw ip sockets. On tcp sockets the DF flag is controlled by the
path MTU discovery option.
Sending a packet larger than the MTU size of the egress interface
returns an EMSGSIZE error.

- Remove sis_unit and use device_printf() and if_printf() instead.
- Use callout_init_mtx() for the callout.
- Remove spls.
- Fix locking for ifmedia to happen in the ifmedia handlers rather than in
sis_ioctl().
- Log an error message if we fail to allocate any resources. Perform
cleanup if we fail to allocate any resources so that we don't leave
a mutex hanging around.

number of cards have been discovered to be matching on the strings of
the cis rather than manufacturer/product id for cards we already had a
prod id for. This is a result of getting the list from the NetBSD
driver which also includes the OID for the cards where such a
distinction mattered (since it was tested against the MAC address we
got from the card). Since we do not try to match OIDs, we do not need
the extra entries and they just waste space.
I'm guessing that some of the dlink entires (DE-660, DE-660+) and many
of the corega cards may fall into this boat and can safely be removed.
the per-cpu data for all CPUs. This is easier to ask users to do than
"figure out how many CPUs you have, now run show pcpu, then run it
once for each CPU you have".

the vast majority of cases, these functions are called without mutexes
held, meaning that in all but two cases, there will be no ordering
issues with doing this, and it will eliminate the need for changes in
the caller. In two cases, mutexes are held, so Giant must be acquired
before those mutexes such that uprintf() and tprintf() recurse Giant
rather than generating a lock order reversal.

that socket during open, not the write socket receive buffer. This
might explain clearing of the sb_state SB_LOCK flag seen occasionally
in soreceive() on fifos.

driver-induced errors, instead be better about propagating error status
upwards. Add more error definitions, courtesy of the linux driver. Fix
a command leak in the ioctl handler. Re-arrange some of the command handlers
to localize error handling.
