Reduce the size of ed a little by removing some CIS based entries (others
likely can be removed too):
o The D-Link DFE-670TXD doesn't need its own entry based on strings.
o The Xircom CompactCard appears to be a TDK design, so list it there by ID
and remove the strings.
Increase the size of ed a little:
o Add support for the Addtron AE-660CT and Addtron AE-660. This is a very
generic NE-2000 clone (so generic that its CIS tags say NE-2000 generic
card!).
take the lock from interrupt context, which causes an implicit
lock order reversal. We've been using the lock carefully enough
that making it a spin lock should not be harmful.
first interface is detached from parent and then bpfdetach() is called.
If the interface was the last carp(4) interface attached to parent, then
the mutex on parent is destroyed. When bpfdetach() calls if_setflags()
we panic on destroyed mutex.
To prevent the above scenario, clear pointer to parent, when we detach
ourselves from parent.
UMA boot pages.
Disable recursion on the general UMA lock now that startup_alloc() no
longer uses it.
Eliminate the variable uma_boot_free. It serves no purpose.
Note: This change eliminates a lock-order reversal between a system
map mutex and the UMA lock. See

times consequently, without checking whether callout has been serviced
or not. (ng_pptpgre and ng_ppp were catched in this behavior).
- In ng_callout() save old item before calling callout_reset(). If the
latter has returned 1, then free this item.
- In ng_uncallout() clear c->c_arg.
Problem reported by: Alexandre Kardanev
First, mutexed callouts are incompatible with netgraph nodes, because
netgraph(4) can guarantee that the function will be called with mutex
held.
Second, nodes should not send data to their neighbor holding their
mutex. A node does not know what stack can it enter sending data in
some direction. May be executing will encounter a place to sleep.
New locking:
- ng_pptpgre_recv() and ng_pptpgre_xmit() must be entered with mutex held.
- ng_pptpgre_recv() and ng_pptpgre_xmit() unlock mutex before
sending data and then return unlocked.
- callout routines acquire mutex themselves.
struct bufs that are persistently held by ext2fs. Ignore any buffers
with this flag in the code in boot() that counts "busy" and dirty
buffers and attempts to sync the dirty buffers, which is done before
attempting to unmount all the file systems during shutdown.
This fixes the problem caused by any ext2fs file systems that are
mounted at system shutdown time, which caused boot() to give up on
a non-zero number of buffers and skip the call to vfs_unmountall().
This left all the mounted file systems in a dirty state and caused
them to all require cleanup by fsck on reboot.
Move the two separate copies of the "busy" buffer test in boot()
to a separate function.
Nuke the useless spl() stuff in the ext2fs ULCK_BUF() macro.
Bring the PRINT_BUF_FLAGS definition in sys/buf.h up to date with
this and previous flag changes.

as yet unknown, those cards report their MAC address a byte at a time.
However, other AX88x90 cards report the MAC address a word at a time.
Add a heuristic which looks at the high order bytes of the first 6
words. If they are all '0', assume the card is behaving like the
Linksys EC2T card. Since the default prefix for these cards appears
to be 00:e0:98, this appears to be a safe heuristic. While some cards
have been observed with different prefixes, they all work with this
heuristic.
I'm unsure if this is a bug in the EC2T card, or if it is a bug in the
initialization of the card. No other OS has this heuristic (although
w/o it, the MAC address that is used works).
listed in different orders. Since it is easy to identify the Modem
resources vs the Ethernet resources by looking at the size, use that
rather than hard coded rids. For such parts, go ahead and guess which
rid we should use based on the size. This guess appears reliable for
the two example cards that I have with different CIS info.

does not clear m_nextpkt for us. The mbufs are sent into netgraph and
then, if they contain a TCP packet delivered locally, they will enter
socket code again. They can pass the first assert in sbappendstream()
because m_nextpkt may be set not in the first mbuf, but deeper in the
chain. So the problem will trigger much later, when local program
reads the data from socket, and an mbuf with m_nextpkt becomes a
first one.
This bug was demasked by revision 1.54, when I made upcall queueable.
Before revision 1.54 there was a very small probability to have 2
mbufs in GRE socket buffer, because ng_ksocket_incoming2() dequeued
the first one immediately.
- in ng_ksocket_incoming2() clear m_nextpkt on all mbufs
read from socket.
- restore rev. 1.54 change in ng_ksocket_incoming().
