'RELENG_7_0_0_RELEASE'.

This commit was manufactured to restore the state of the 7.0-RELEASE image.

Don't call bus_deactivate_resource() explicitly before calling

bus_release_resource().  This is needed for pc98 by upcoming nexus related
change.

o break newbus api: add a new argument of type driver_filter_t to

  bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

Make cm(4) driver MPSAFE.

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we

2005-09-19T03:10:21+00:00

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.

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and

2005-08-09T10:20:02+00:00

IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

Stop embedding struct ifnet at the top of driver softcs. Instead the

2005-06-10T16:49:24+00:00

struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

Replace the if_name and if_unit members of struct ifnet with new members

2003-10-31T18:32:15+00:00

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.
