c269c9fb36 Use a consistent style and one much closer to the rest of /usr/src 2001-01-06 14:00:42 +00:00

ea11d3cf1c Use .include <bsd.kmod.mk> to get to ../../*/conf/kmod.mk instead of
encoding the relative path.

1b38e19179 Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk.  This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

17f54b4408 Add ${DEBUG_FLAGS} to CFLAGS in bsd.kmod.mk, not in scattered module
makefiles.  Bad examples in fxp/Makefile keep getting copied to new
makefiles.

cf16a7efdb Attempt to fix a problem with receiving packets on USB ethernet interfaces.
Packets are received inside USB bulk transfer callbacks, which run at
splusb() (actually splbio()). The packet input queues are meant to be
manipulated at splimp(). However the locking apparently breaks down under
certain circumstances and the input queues can get trampled.

There's a similar problem with if_ppp, which is driven by hardware/tty
interrupts from the serial driver, but which must also manipulate the
packet input queues at splimp(). The fix there is to use a netisr, and
that's the fix I used here. (I can hear you groaning back there. Hush up.)

The usb_ethersubr module maintains a single queue of its own. When a
packet is received in the USB callback routine, it's placed on this
queue with usb_ether_input(). This routine also schedules a soft net
interrupt with schednetisr(). The ISR routine then runs later, at
splnet, outside of the USB callback/interrupt context, and passes the
packet to ether_input(), hopefully in a safe manner.

The reason this is implemented as a separate module is that there are
a limited number of NETISRs that we can use, and snarfing one up for
each driver that needs it is wasteful (there will be three once I get
the CATC driver done). It also reduces code duplication to a certain
small extent. Unfortunately, it also needs to be linked in with the
usb.ko module in order for the USB ethernet drivers to share it.

Also removed some uneeded includes from if_aue.c and if_kue.c

d7156780d3 Removed special rules for building and cleaning device interface files
and empty options files.  The rules are now generated automatically in
bsd.kmod.mk.  Cleaned up related things ($S and ${CLEANFILES}).

56e56ad17a Make this compile (remove vnode_if.c from SRCS) and clean properly
(add opt_bus.h to CLEANFILES).
