The DMA logic in firmwares < v3.3.0 embedded in the PCAN-PCIe FD cards
family is not capable of handling a mix of 32-bit and 64-bit logical
addresses. If the board is equipped with 2 or 4 CAN ports, then such a
situation might lead to a PCIe Bus Error "Malformed TLP" packet

This patch adds a workaround that requests only 32-bit DMA addresses

After device is stopped we reset the rings by moving all free buffers
to positions [0, cnt - 2], and clear the position cnt - 1 in the ring.
We then proceed to clear the read/write pointers. This means that if
we try to reset the ring again the code will assume that the next to
fill buffer is at position 0 and swap it with cnt - 1. Since we
previously cleared position cnt - 1 it will lead to leaking the first
buffer and leaving ring in a bad state.
This scenario can only happen if FW communication fails, in which case
the ring will never be used again, so the fact it's in a bad state will
not be noticed. Buffer leak is the only problem. Don't try to move
buffers in the ring if the read/write pointers indicate the ring was
never used or have already been reset.
nfp_net_clear_config_and_disable() is now fully idempotent.
Found by code inspection, FW communication failures are very rare,
and reconfiguring a live device is not common either, so it's unlikely
anyone has ever noticed the leak.

Problem:
In vxlan_newlink, a default fdb entry is added before register_netdev.
The default fdb creation function also notifies user-space of the
fdb entry on the vxlan device which user-space does not know about yet.
(RTM_NEWNEIGH goes before RTM_NEWLINK for the same ifindex).
This patch fixes the user-space netlink notification ordering issue
with the following changes:
- decouple fdb notify from fdb create.
- Move fdb notify after register_netdev.
- Call rtnl_configure_link in vxlan newlink handler to notify

Commit f599c64fdf ("xen-netfront: Fix race between device setup and

happens before we do register_netdev() so using netdev->name in
xennet_init_queue() is incorrect, we end up with the following in
/proc/interrupts:
60: 139 0 xen-dyn -event eth%d-q0-tx
61: 265 0 xen-dyn -event eth%d-q0-rx
62: 234 0 xen-dyn -event eth%d-q1-tx
63: 1 0 xen-dyn -event eth%d-q1-rx
and this looks ugly. Actually, using early netdev name (even when it's
already set) is also not ideal: nowadays we tend to rename eth devices
and queue name may end up not corresponding to the netdev name.
Use nodename from xenbus device for queue naming: this can't change in VM's
lifetime. Now /proc/interrupts looks like

Also first free the irq (or stop the worker respectively) such that

"imply HWMON" was supposed to ensure that the SFP phy code can be built
with HWMON enabled or disabled while at the same time ensuring that
HWMON is not built as module if SFP is built into the kernel.
Unfortunately, that does not work as intended. With "allmodconfig", it
results in several unrelated HWMON drivers to be disabled instead of
being built as module as expected.
Let's use the old "depends on HWMON || HWMON=n" instead. This is slightly
different (it enforces SFP to be built as module if HWMON is built as
module), but it is better than the alternative of using "IS_REACHABLE()"
in the driver since that would disable sensor support if HWMON is built
as module and SFP is built into the kernel.

For some time now, if you load the bonding driver and configure bond
parameters via sysfs using minimal config options, such as specifying
nothing but the mode, relying on defaults for everything else, modes
that cannot use arp monitoring (802.3ad, balance-tlb, balance-alb) all
wind up with both arp_interval=0 (as it should be) and miimon=0, which
means the miimon monitor thread never actually runs. This is particularly
problematic for 802.3ad.
For example, from an LNST recipe I've set up:
$ modprobe bonding max_bonds=0"
$ echo "+t_bond0" > /sys/class/net/bonding_masters"
$ ip link set t_bond0 down"
$ echo "802.3ad" > /sys/class/net/t_bond0/bonding/mode"
$ ip link set ens1f1 down"
$ echo "+ens1f1" > /sys/class/net/t_bond0/bonding/slaves"
$ ip link set ens1f0 down"
$ echo "+ens1f0" > /sys/class/net/t_bond0/bonding/slaves"
$ ethtool -i t_bond0"
$ ip link set ens1f1 up"
$ ip link set ens1f0 up"
$ ip link set t_bond0 up"
$ ip addr add 192.168.9.1/24 dev t_bond0"
$ ip addr add 2002::1/64 dev t_bond0"
This bond comes up okay, but things look slightly suspect in
/proc/net/bonding/t_bond0 output:
$ grep -i mii /proc/net/bonding/t_bond0
MII Status: up
MII Polling Interval (ms): 0
MII Status: up
MII Status: up
Now, pull a cable on one of the ports in the bond, then reconnect it, and
you'll see:
Slave Interface: ens1f0
MII Status: down
Speed: 1000 Mbps
Duplex: full
I believe this became a major issue as of commit 4d2c0cda07, which for
802.3ad bonds, sets slave->link = BOND_LINK_DOWN, with a comment about
relying on link monitoring via miimon to set it correctly, but since the
miimon work queue never runs, the link just stays marked down.
If we simply tweak bond_option_mode_set() slightly, we can check for the
non-arp modes having no miimon value set, and insert BOND_DEFAULT_MIIMON,
which gets things back in full working order. This problem exists as far
back as 4.14, and might be worth fixing in all stable trees since, though
the work-around is to simply specify an miimon value yourself.

The flow counters binding support commit introduced a code change where
none NULL 'rule_dest' is always passed to mlx5_add_flow_rules, this breaks

The fix uses the equivalent 'dest_num' value instead of dest pointer
at the failed check.
