1f6973c5b4 When reusing a pointer as a number, at least cast it 
to uintptr_t rather than u_int to avoid warnings on
64 bits architectures.

91e97a8266 In an SMP environment post-Giant it is no longer safe to blindly 
dereference the struct sigio pointer without any locking.  Change
fgetown() to take a reference to the pointer instead of a copy of the
pointer and call SIGIO_LOCK() before copying the pointer and
dereferencing it.

f2ba8326cd Use standards visibility conditionals to conditionalize most of this 
header (details on how the visibility conditionals work are available
in <sys/cdefs.h>).  Use standard types instead of BSD specific ones,
so that this header compiles in the standards case (specifically this
means changing `u_int' to `unsigned int').

a7f6243009 Fixed some of the namespace pollution in rev.1.33. <sys/systm.h> was 
included here because it was once a prerequisite of <sys/mutex.h>
although that bug was fixed long ago.

37c841831f Be consistent about "static" functions: if the function is marked 
static in its prototype, mark it static at the definition too.

afbe3a0f81 Add the "Monitor" interface flag. 
Setting this flag on an ethernet interface blocks transmission of packets
and discards incoming packets after BPF processing.

This is useful if you want to monitor network trafic but not interact
with the network in question.

06204d34a8 Convert most printf()s to if_printf()s. 2002-09-24 17:37:32 +00:00
Brooks Davis
fa882e87a5 Add a new helper function if_printf() modeled on device_printf(). The 
function takes a struct ifnet pointer followed by the usual printf
arguments and prints "<interfacename>: " before the results of printf.
Since this is the primary form of printf calls in network device drivers
and accounts for most uses of the ifnet menber if_unit, this
significantly simplifies many printf()s.

015d72e0c9 Make bridging and layer2-ipfw obey net.inet.ip.fw.one_pass. 
I should have committed this ages ago.

The MFC for if_ethersubr.c could be done in the usual few days (only
ipfw2 uses it), the one for bridge.c should probably wait until
after 4.7 because it changes an existing though mostly undocumented
behaviour (on which i hope nobody relies). All in all, i'll wait for
both things unless there is demand.

ffb079be0c Implement user-setable promiscuous mode (a new `promisc' flag for ifconfig(8)). 
Also, for all interfaces in this mode pass all ethernet frames to upper layer,
even those not addressed to our own MAC, which allows packets encapsulated
in those frames be processed with packet filters (ipfw(8) et al).
