Subject: Re: [PATCH net-2.6][NEIGH] Updating affected neighbours when about MAC address change

Hello,

First, it indeed can be handled by user space. (even though it should
be done twice, once for ifconig of net-tools  and once for ip of
iproute2) / However, we have already
methods which deal with bringing down an interface - neigh_ifdown(),
and changing MAC address of an interface (neigh_changeaddr). So why
not do it from
the kernel ?
