MAC_FMT had only one user and we tried to get rid of
that, but this created more problems than it solved.
As a result, this reverts three commits:
235365f3aaaa10b7056293877c0ead50425f25c7 ("net/8021q/vlan_dev.c: Use
print_mac."), fea5fa875eb235dc186b1f5184eb36abc63e26cc ("[NET]: Remove
MAC_FMT"), and 8f789c48448aed74fe1c07af76de8f04adacec7d ("[NET]:
Elminate spurious print_mac() calls.")

The neigh_hash_grow() may update the tbl->hash_rnd value, which
is used in all tbl->hash callbacks to calculate the hashval.
Two lookup routines may race with this, since they call the
->hash callback without the tbl->lock held. Since the hash_rnd
is changed with this lock write-locked moving the calls to ->hash
under this lock read-locked closes this gap.

RTM_NEWLINK allows for already existing links to be modified. For this
purpose do_setlink() is called which expects address attributes with a
payload length of at least dev->addr_len. This patch adds the necessary
validation for the RTM_NEWLINK case.
The address length for links to be created is not checked for now as the
actual attribute length is used when copying the address to the netdevice
structure. It might make sense to report an error if less than addr_len
bytes are provided but enforcing this might break drivers trying to be
smart with not transmitting all zero addresses.

When asked to blink LEDs the tg3 driver behaves when using:
ethtool -p ethX
The default value for data is zero, and other drivers interpret this
as blink forever (or at least a really long time). The tg3 driver
interprets this as blink once. All drivers should have the same
behaviour.

When deleting the veth driver, veth_close calls netif_carrier_off
for the two extremities of the network device. netif_carrier_off on
the peer device will fire an event and hold a reference on the peer
device. Just after, the peer is unregistered taking the rtnl_lock while
the linkwatch_event is scheduled. If __linkwatch_run_queue does not
occurs before the unregistering, unregister_netdevice will wait for
the dev refcount to reach zero holding the rtnl_lock and linkwatch_event
will wait for the rtnl_lock and hold the dev refcount.

packet data
As reported by Tomas Simonaitis <tomas.simonaitis@gmail.com>,
inserting new data in skbs queued over {ip,ip6,nfnetlink}_queue
triggers a SKB_LINEAR_ASSERT in skb_put().
Going back through the git history, it seems this bug is present since
at least 2.6.12-rc2, probably even since the removal of
skb_linearize() for netfilter.
Linearize non-linear skbs through skb_copy_expand() when enlarging
them. Tested by Thomas, fixes bugzilla #9933.

Commit a0a400d79e3dd7843e7e81baa3ef2957bdc292d0 ("[NET]: dev_mcast:
add multicast list synchronization helpers") from you introduced a new
field "da_synced" to struct dev_addr_list that is not properly
initialized to 0. So when any of the current users (8021q, macvlan,
mac80211) calls dev_mc_sync/unsync they mess the address list for both
devices.
The attached patch fixed it for me and avoid future problems.
