respectivly. This will allow one to have a kernel with both devices
present and use it for multiple boards with different types of RTC
sitting on a bus.
Discussed with: imp
after the corresponding interface has been destroyed:
(1) Add an ifnet refcount, ifp->if_refcount. Initialize it to 1 in
if_alloc(), and modify if_free_type() to decrement and check the
refcount.
(2) Add new if_ref() and if_rele() interfaces to allow kernel code
walking global interface lists to release IFNET_[RW]LOCK() yet
keep the ifnet stable. Currently, if_rele() is a no-op wrapper
around if_free(), but this may change in the future.
(3) Add new ifnet field, if_alloctype, which caches the type passed
to if_alloc(), but unlike if_type, won't be changed by drivers.
This allows asynchronous free's of the interface after the
driver has released it to still use the right type. Use that
instead of the type passed to if_free_type(), but assert that
they are the same (might have to rethink this if that doesn't
work out).
(4) Add a new ifnet_byindex_ref(), which looks up an interface by
index and returns a reference rather than a pointer to it.
(5) Fix if_alloc() to fully initialize the if_addr_mtx before hooking
up the ifnet to global lists.
(6) Modify sysctls in if_mib.c to use ifnet_byindex_ref() and release
the ifnet when done.
When this change is MFC'd, it will need to replace if_ispare fields
rather than adding new fields in order to avoid breaking the binary
interface. Once this change is MFC'd, if_free_type() should be
removed, as its 'type' argument is now optional.
This refcount is not appropriate for counting mbuf pkthdr references,
and also not for counting entry into the device driver via ifnet
function pointers. An rmlock may be appropriate for the latter.
Rather, this is about ensuring data structure stability when reaching
an ifnet via global ifnet lists and tables followed by copy in or out
of userspace.

The main problem is that sbappendrecord_locked() relies on sbcompress()
to set sb_mbtail. This will not happen if sbappendrecord_locked() is
called with mbuf chain made of exactly one mbuf (i.e. m0->m_next == NULL).
In this case sbcompress() will be called with m == NULL and will do
nothing. I'm not entirely sure if m == NULL is a valid argument for
sbcompress(), and, it rather pointless to call it like that, but keep
calling it so it can do SBLASTMBUFCHK().
The problem is triggered by the SOCKBUF_DEBUG kernel option that
enables SBLASTRECORDCHK() and SBLASTMBUFCHK() checks.

Include opt_ddb.h for that. Now you can actually boot with
-d and set breakpoints using function names.
o Make sure to include opt_msgbuf.h.
o Carve out the first 1MB of physical memory. The MPC85xx has
DMA problems with addresses below 1MB. Ideally busdma knows
how to avoid allocating below 1MB for MPC85xx, but that
requires a bit more work. For now, ignore the 1MB of DRAM.
Match the bracketing in netstat.
Since the cleanup of MROUTING, ports have broken because they
expect to include <netinet/ip_mroute.h> without including
<sys/queue.h>. Fix breakage at source.
The real fix, of course, is to fix the MROUTING APIs by blowing them
away and replacing them with something else...
number of queued packets in watchdog timeout handler. If there are
no queued packets just print a informational message and return
without resetting controller. Also fix to invoke correct Tx
completion handler as 3C905B needs different handler.
Previously it used to clear the flag only when the transmit queue
is empty which may slow down Tx performance.
While I'm here check whether driver is running and whether we can
queue more packets in if_start handler. This fixes occasional
watchdog timeouts.
