net/bluetooth/l2cap_core.c: In function ‘l2cap_recv_frame’:
net/bluetooth/l2cap_core.c:3612:15: warning: ‘sk’ may be used uninitialized in this function
net/bluetooth/l2cap_core.c:3612:15: note: ‘sk’ was declared here

Actually the problem is in the inline function l2cap_data_channel(), we
branch to the label 'done' which tests 'sk' before we set it to anything.

Initialize it to NULL to fix this.

Since now when bonding uses rx_handler, all traffic going into bond
device goes thru bond_handle_frame. So there's no need to go back into
bonding code later via ptype handlers. This patch converts
original ptype handlers into "bonding receive probes". These functions
are called from bond_handle_frame and they are registered per-mode.

Note that vlan packets are also handled because they are always untagged
thanks to vlan_untag()

Note that this also allows arpmon for eth-bond-bridge-vlan topology.

When processing an ACK for ADD_IP parameter, we only release
the routes on non-active transports.  This can cause a wrong
source address to be used.  We can release the routes and
cause new route lookups and source address selection so that
new addresses can be used as source.  Additionally, we don't need
to lookup routes for all transports at the same time.  We can let
the transmit code path update the cached route when the transport
actually sends something.

When we have have to remove a transport due to ASCONF, we move
the data to a new active path.  This can trigger CACC algorithm
to not mark that data as missing when SACKs arrive.  This is
because the transport passed to the CACC algorithm is the one
this data is sitting on, not the one it was sent on (that one
may be gone).  So, by sending the original transport (even if
it's NULL), we may start marking data as missing.
