CVS commit: src/sys/net

["David Young" <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung

Modified Files:
        src/sys/net: if.c if.h

Log Message:
Start to untangle the ifnet ioctls mess.

Add ifnet functions, if_mcast_op(), if_flags_set(), and if_addr_init()
for adding/deleting multicast addresses, modifying the if_flags,
and initializing local/remote addresses.  Make ifpromisc() use
if_flags_set().  Protocols and network drivers should use these
instead of ifp->if_ioctl() calls.  Subsequent commits will
replace ifp->if_ioctl(SIOCADDMULTI| SIOCDELMULTI| SIOCSIFDSTADDR|
SIOCINITIFADDR| SIOCSIFFLAGS) calls with calls to the new functions.

Use a mutex(9) to synchronize ifp->if_ioctl() calls originating in
userland.  Also synchronize ifp->if_ioctl() calls with ifnet detachment
and reclamation.
