fa6a7ef6e4 Process events from the ATM drivers. Carrier change and PVC change
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.

95f04def4b fix a cut-n-paste error.
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

1cafed3941 Update netisr handling; Each SWI now registers its queue, and all queue
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.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

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.

5dfe609dd1 Add two loader tuneables that allow one to change the maximum number of
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.

7dd982591b Some more updates for the new world order:
- 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.

0aef141cd0 Attempt to make the ng_fec module play nice with BPF again. Things have
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.

7874f606d5 Introduce a new taskqueue that runs completely free of Giant, and in
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.

cd72f2180b Change struct file f_data to un_data, a union of the correct struct
pointer types, and remove a huge number of casts from code using 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
commit.

the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}.
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).

Has been seen to work on several cards and communicating with

We are still talking with 3com to try get them to allow us to include
the firmware for their pccard in the driver but the driver is here..
In the mean time
it can be downloaded from the 3com website and loaded using the utility
bt3cfw(8) (supplied) (instructions in the man page)
