messages are forwarded as netgraph control messages to the node
that is connected to the manage hook. If that hook is not connected,
the event is lost. Flow control events are converted to netgraph
flow control messages and send along the hook that is connected to
the flow controlled VC. ACR change events are converted to control
messages and sent along the hook for the given VC.
in the case where the bridge node was closed down but a timeout
still applied to it, the final reference to the node was freeing the private
data structure using the wrong malloc type.

drain routines are done by swi_net, which allows for better queue control
at some future point. Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

queue items that can be allocated by netgraph and the number of free queue
items that are cached on a private list.
Netgraph places an upper limit on the number of queue items it may allocate.
When there is a large number of netgraph messages travelling through the
system (100k/sec and more) there is a high probability, that messages get
queued at the nodes and netgraph runs out of queue items. In this case the data
flow through netgraph gets blocked. The tuneable for the number of free
items lets one trade memory for performance.
The tunables are also available as read-only sysctls.

- Make transmission of packets work again. This stopped working because
ether_ifattach() was forcing ifp->if_output to be ether_output() and
clobbering our attempt to override this vector with a pointer to
ng_fec_output(). Move the overriding of ifp->if_output to after
ether_ifattach().
- Abandon the use of the netgraph ng_ether_input_p hook for snagging
incoming frames, and instead override the ifp->if_input vector for
interfaces that have been aggregated into our bundle. (I would have
loved to have written things this way in the first place, but I
didn't want to have to be the one to implement the if_input hook
and change all the drivers.) This avoids collisions with the ng_ether
module, which uses the same hook. Each aggregated device now calls
ng_fec_input() directly, which then fakes up the rcvif pointer
before invoking ifp->if_input itself.
This module should actually work now.
changed since this code was written:
- The ng_ether_input_p hook only accepts two arguments now: the pointer
to the ether header structure is gone.
- It's no longer necessary to cons up a fake ether header before passing
incoming packets to BPF_MTAP().
ng_fec_input() has been modified to account for these two changes.
Running tcpdump on fec0 should work now.

turns runs its tasks free of Giant too. It is intended that as drivers
become locked down, they will move out of the old, Giant-bound taskqueue
and into this new one. The old taskqueue has been renamed to
taskqueue_swi_giant, and the new one keeps the name taskqueue_swi.
we have the rc4 code already in the kernel (via wlan stuff or awi).
Add a dependency on the rc4 module so if it doesn't exist then load it.

Change struct xfile xf_data to xun_data (ABI is still compatible).
If we need to add a #define for f_data and xf_data we can, but I don't
think it will be necessary. There are no operational changes in this

o Fix a bpf_compat issue where malloc() was defined to just call
bpf_alloc() and pass the 'canwait' flag(s) along. It's been changed
to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
flag (and only one of those two).
