On big-endian machines, functions converting between tunnel ID
and VNI use the three LSBs of tunnel ID storage to map VNI.
The comparison function eq_tun_id_and_vni(), on the other hand,
attempted to map the VNI from the three MSBs. Fix it by using
the same check implemented on LE, which maps VNI from the three
LSBs of tunnel ID.

Marc Kleine-Budde says:
====================
pull-request: can 2017-10-19
this is a pull request of 11 patches for the upcoming 4.14 release.
There are 6 patches by ZHU Yi for the flexcan driver, that work around
the CAN error handling state transition problems found in various
incarnations of the flexcan IP core.
The patch by Colin Ian King fixes a potential NULL pointer deref in the
CAN broad cast manager (bcm). One patch by me replaces a direct deref of a RCU
protected pointer by rcu_access_pointer. My second patch adds missing
OOM error handling in af_can. A patch by Stefan Mätje for the esd_usb2
driver fixes the dlc in received RTR frames. And the last patch is by
Wolfgang Grandegger, it fixes a busy loop in the gs_usb driver in case
it runs out of TX contexts.

syzkaller got crashes at dismantle time [1]
It is not correct to test (tun->flags & IFF_NAPI) in tun_napi_disable()
and tun_napi_del() : Each tun_file can have different mode, depending
on how they were created.
Similarly I have changed tun_get_user() and tun_poll_controller()
to use the new tfile->napi_enabled boolean.

inet6addr_validator chain was added by commit 3ad7d2468f79f ("Ipvlan
should return an error when an address is already in use") to allow
address validation before changes are committed and to be able to
fail the address change with an error back to the user. The address
validation is not done for addresses received from router
advertisements.
Handling RAs in softirq context is the only reason for the notifier
chain to be atomic versus blocking. Since the only current user, ipvlan,
of the validator chain ignores softirq context, the notifier can be made
blocking and simply not invoked for softirq path.
The blocking option is needed by spectrum for example to validate
resources for an adding an address to an interface.

Implement fallback compatibility strings for R-Car Gen 1 and 2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.
Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The
approach that has been consistently taken for other IP blocks is to name
common code, compatibility strings and so on after R-Car Gen2.

Rename structures describing R-Car SoCs as rcar_gen[12]_*
rather than r8a77[79]x_*. This seems a little easier on the
eyes. And will make things slightly cleaner in a follow-up
patch that adds fallback-compatibility strings for these SoCs.
Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The
approach that has been consistently taken for other IP blocks is to name
common code, compatibility strings and so on after R-Car Gen2.
Also rename sh_eth_set_rate_r8a777x as sh_eth_set_rate_rcar as
it it is used by the R-Car generations supported by the driver.
This patch should have no run-time effect and
is compile-tested only.

Out of order flow is not working for iWARP.
This patch got cut out from initial series that added out
of order support for iWARP.
Make out of order code common for iWARP and iSCSI.
Add new configuration option CONFIG_QED_OOO. Set by
qedr and qedi Kconfigs.

This patch reverts earlier commit b13ba1b83f52 ("macvlan: forbid L2
fowarding offload for macvtap"). The reason for reverting this is because
the original patch no longer fixes what it previously did as the
underlying structure has changed for macvtap. Specifically macvtap
originally pulled packets directly off of the lowerdev. However in commit
6acf54f1cf0a ("macvtap: Add support of packet capture on macvtap device.")
that code was changed and instead macvtap would listen directly on the
macvtap device itself instead of the lower device. As such, the L2
forwarding offload should now be able to provide a performance advantage of
skipping the checks on the lower dev while not introducing any sort of
regression.

If sending messages with no cable connected, it quickly happens that
there is no more TX context available. Then "gs_can_start_xmit()"
returns with "NETDEV_TX_BUSY" and the upper layer does retry
immediately keeping the CPU busy. To fix that issue, I moved
"atomic_dec(&dev->active_tx_urbs)" from "gs_usb_xmit_callback()" to
the TX done handling in "gs_usb_receive_bulk_callback()". Renaming
"active_tx_urbs" to "active_tx_contexts" and moving it into
"gs_[alloc|free]_tx_context()" would also make sense.

The dlc member of the struct rx_msg contains also the ESD_RTR flag to
mark received RTR frames. Without the fix the can_dlc value for received
RTR frames would always be set to 8 by get_can_dlc() instead of the
received value.
