I saw the following BUG when ->newlink() fails in rtnl_newlink():
[ 40.240058] kernel BUG at net/core/dev.c:6438!
this is due to free_netdev() is not supposed to be called before
netdev is completely unregistered, therefore it is not correct
to call free_netdev() here, at least for ops->newlink!=NULL case,
many drivers call it in ->destructor so that rtnl_unlock() will
take care of it, we probably don't need to do anything here.

Recent patch
bonding: add netlink attributes to slave link dev (1d3ee88ae0)
Introduced yet another device specific way to access slave information
over rtnetlink. There is one already there for bridge.
This patch introduces generic way to do this, for getting and setting
info as well by extending link_ops. Later on, this new interface will
be used for bridge ports as well.

Fix the iproute2 command `bridge vlan show`, after switching from
rtgenmsg to ifinfomsg.
Let's start with a little history:
Feb 20: Vlad Yasevich got his VLAN-aware bridge patchset included in
the 3.9 merge window.
In the kernel commit 6cbdceeb, he added attribute support to
bridge GETLINK requests sent with rtgenmsg.
Mar 6th: Vlad got this iproute2 reference implementation of the bridge
vlan netlink interface accepted (iproute2 9eff0e5c)
Apr 25th: iproute2 switched from using rtgenmsg to ifinfomsg (63338dca)
http://patchwork.ozlabs.org/patch/239602/http://marc.info/?t=136680900700007
Apr 28th: Linus released 3.9
Apr 30th: Stephen released iproute2 3.9.0
The `bridge vlan show` command haven't been working since the switch to
ifinfomsg, or in a released version of iproute2. Since the kernel side
only supports rtgenmsg, which iproute2 switched away from just prior to
the iproute2 3.9.0 release.
I haven't been able to find any documentation, about neither rtgenmsg
nor ifinfomsg, and in which situation to use which, but kernel commit
88c5b5ce seams to suggest that ifinfomsg should be used.
Fixing this in kernel will break compatibility, but I doubt that anybody
have been using it due to this bug in the user space reference
implementation, at least not without noticing this bug. That said the
functionality is still fully functional in 3.9, when reversing iproute2
commit 63338dca.
This could also be fixed in iproute2, but thats an ugly patch that would
reintroduce rtgenmsg in iproute2, and from searching in netdev it seams
like rtgenmsg usage is discouraged. I'm assuming that the only reason
that Vlad implemented the kernel side to use rtgenmsg, was because
iproute2 was using it at the time.

Commit 6681712d67
vxlan: generalize forwarding tables
relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr().
This allows users to add multicast addresses using the fdb API. However,
the check in rtnl_fdb_del() still uses a more strict
is_valid_ether_addr() which rejects multicast addresses. Thus it
is possible to add an fdb that can not be later removed.
Relax the check in rtnl_fdb_del() as well.

This patch generalizes VXLAN forwarding table entries allowing an administrator
to:
1) specify multiple destinations for a given MAC
2) specify alternate vni's in the VXLAN header
3) specify alternate destination UDP ports
4) use multicast MAC addresses as fdb lookup keys
5) specify multicast destinations
6) specify the outgoing interface for forwarded packets
The combination allows configuration of more complex topologies using VXLAN
encapsulation.

If the driver does not support the ndo_op use the generic
handler for it. This should work in the majority of cases.
Eventually the fdb_dflt_add call gets translated into a
__dev_set_rx_mode() call which should handle hardware
support for filtering via the IFF_UNICAST_FLT flag.
Namely IFF_UNICAST_FLT indicates if the hardware can do
unicast address filtering. If no support is available
the device is put into promisc mode.

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.

Change the dflt fdb dump handler to use RTM_NEWNEIGH to
be compatible with bridge dump routines.
The dump reply from the network driver handlers should
match the reply from bridge handler. The fact they were
not in the ixgbe case was effectively a bug. This patch
resolves it.
Applications that were not checking the nlmsg type will
continue to work. And now applications that do check
the type will work as expected.

Commit e5a55a8987 ('net: create generic
bridge ops') broke the handling of a non-zero starting index in
rtnl_bridge_getlink() (based on the old br_dump_ifinfo()).
When the starting index is non-zero, we need to increment the current
index for each entry that we are skipping. Also, we need to check the
index before both cases, since we may previously have stopped
iteration between getting information about a device from its master
and from itself.
