These is no need to hold dst before calling rt6_remove_exception_rt().
The call to dst_hold_safe() in ip6_link_failure() was for ip6_del_rt(),
which has been removed in Commit 93531c67 ("net/ipv6: separate
handling of FIB entries from dst based routes"). Otherwise, it will
cause a dst leak.

This patch is to simply remove the dst_hold_safe() call before calling
rt6_remove_exception_rt() and also do the same in ip6_del_cached_rt().
It's safe, because the removal of the exception that holds its dst's
refcnt is protected by rt6_exception_lock.

Using 2.5G speed relies on the SerDes lanes being configured
accordingly. The lanes have to be reconfigured to switch between
1G and 2.5G, and for now only the bootloader does this configuration.

In the case we add a Comphy driver to handle switching the lanes
dynamically, it's better for now to stick with supporting only 1G and
add advertisement for 2.5G once we really are capable of handling both
speeds without problem.

Since the interface mode is initialy taken from the DT, we want to make
sure that adding comphy support won't break boards that don't update
their dtb.

When re-registering a user mr, the mpt information for the
existing mr when running SRIOV is obtained via the QUERY_MPT
fw command. The returned information includes the mpt's lkey.

This retrieved mpt information is used to move the mpt back
to hardware ownership in the rereg flow (via the SW2HW_MPT
fw command when running SRIOV).

The fw API spec states that for SW2HW_MPT, the lkey field
must be zero. Any ConnectX-3 PF driver which checks for strict spec
adherence will return failure for SW2HW_MPT if the lkey field is not
zero (although the fw in practice ignores this field for SW2HW_MPT).

Thus, in order to conform to the fw API spec, set the lkey field to zero
before invoking SW2HW_MPT when running SRIOV.

The life-checking function, which is used by kAFS to make sure that a call
is still live in the event of a pending signal, only samples the received
packet serial number counter; it doesn't actually provoke a change in the
counter, rather relying on the server to happen to give us a packet in the
time window.

Fix this by adding a function to force a ping to be transmitted.

kAFS then keeps track of whether there's been a stall, and if so, uses the
new function to ping the server, resetting the timeout to allow the reply
to come back.

If there's a stall, a ping and the call is *still* stalled in the same
place after another period, then the call will be aborted.

Certain flows need to access the rdma-info structure, for example dcbx
update flows. In some cases there can be a race between the allocation or
deallocation of the structure which was done in roce start / roce stop and
an asynchrounous dcbx event that tries to access the structure.
For this reason, we move the allocation of the rdma_info structure to be
similar to the iscsi/fcoe info structures which are allocated during device
setup.
We add a new field of "active" to the struct to define whether roce has
already been started or not, and this is checked instead of whether the
pointer to the info structure.

====================
pull-request: can 2018-11-09

this is a pull request of 20 patches for net/master.

First we have a patch by Oliver Hartkopp which changes the raw socket's
raw_sendmsg() to return an error value if the user tries to send a CANFD
frame to a CAN-2.0 device.

The next two patches are by Jimmy Assarsson and fix potential problems
in the kvaser_usb driver.

YueHaibing's patches for the ucan driver fix a compile time warning and
remove a duplicate include.

Eugeniu Rosca patch adds more binding documentation to the rcar_can
driver bindings. The next two patches are by Fabrizio Castro for the
rcar_can driver and fixes a problem in the driver's probe function and
document the r8a774a1 binding.

Lukas Wunner's patch fixes a recpetion problem in hi311x driver by
switching from edge to level triggered interruts.

The next three patches all target the flexcan driver. Pankaj Bansal's
patch unconditionally unlocks the last mailbox used for RX. Alexander
Stein provides a better workaround for a hardware limitation when
sending RTR frames, by using the last mailbox for TX, resulting in fewer
lost frames. The patch by me simplyfies the driver, by making a runtime
value a compile time constant.

The following 4 patches are by me and provide the groundwork for the
next patches by Oleksij Rempel. To avoid code duplication common code in
the common CAN driver infrastructure is factured out and error handling
is cleaned up.

The next 4 patches are by Oleksij Rempel and fix the problem in the
flexcan driver that other processes see TX frames arrive out of order
with ragards to a RX'ed frame (which are send by a different system on
the CAN bus as the result of our TX frame).

Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW
uses this channel for DMAE operations (e.g., TIME_SYNC implementation).
Driver also uses the same channel 0 for DMAE operations for some of the PFs
(e.g., PF0 on Port0). This could lead to concurrent access to the DMAE
channel by FW and driver which is not legal. Hence need to assign unique
DMAE id for FW.
Currently following DMAE channels are used by the clients,
  MFW - OCBB/OCSD functionality uses DMAE channel 14/15
  Driver 0-3 and 8-11 (for PF dmae operations)
         4 and 12 (for stats requests)
