net: vxlan: when lower dev unregisters remove vxlan dev as well
We can create a vxlan device with an explicit underlying carrier.
In that case, when the carrier link is being deleted from the
system (e.g. due to module unload) we should also clean up all
created vxlan devices on top of it since otherwise we're in an
inconsistent state in vxlan device. In that case, the user needs
to remove all such devices, while in case of other virtual devs
that sit on top of physical ones, it is usually the case that
these devices do unregister automatically as well and do not
leave the burden on the user.
This work is not necessary when vxlan device was not created with
a real underlying device, as connections can resume in that case
when driver is plugged again. But at least for the other cases,
we should go ahead and do the cleanup on removal.
We don't register the notifier during vxlan_newlink() here since
I consider this event rather rare, and therefore we should not
bloat vxlan's core structure unecessary. Also, we can simply make
use of unregister_netdevice_many() to batch that. fdb is flushed
upon ndo_stop().
E.g. `ip -d link show vxlan13` after carrier removal before

====================
Intel Wired LAN Driver Updates, ixgbe: Add LER support
The following patches add Live Error Recovery (LER) support to the
ixgbe driver. This support also improves behavior in Thunderbolt
environments. This involves checking all register reads for a
value of all ones and when that is seen, to read the status
register, which should never properly return all ones, to
confirm whether the received value was correct. When this detects
a removal, the hw_addr field is cleared to indicate the removal.
This then blocks subsequent access to the device registers.
All register access macros have been changed to static inline
functions and all register accesses now use them.· Macro versions
are temporarily provided.
The __IXGBE_DOWN bit is no longer overloaded to also mean that
device removal has been initiated. Now the bit can be used to
protect ixgbe_down from multiple entry via test_and_set_bit. A
needed smp_mb__before_clear_bit was also added.
V2 Changes:
- Use ACCESS_ONCE where needed, thanks to Ben Hutchings
- Fix crash on module removal
- Use boolean values for boolean returns instead of 0 and 1
- Reword Kconfig help text
V3 Changes:
- Drop config option, per David Miller
- Drop tail register write checks, per Alexander Duyck
- Change writeq implementation to a static inline, thanks to Joe Perches
V4 Changes:
- Change __IXGBE_REMOVE to __IXGBE_REMOVING, per Scott Feldman's comment
- Add #define writeq writeq, per Alexander Duyck
- Change static inline functions to lower case, per David Miller
- Use new lower case names in added and modified register accesses
- Provide temporary upper case macros for register access functions
- Change IXGBE_REMOVED from macro to static inline and change references
- Correct IXGBE_WRITE_FLUSH to properly enclose parameter expansion

I don't have this hardware, so these patches have only been

update function
Detail of the changes (v1):

- fix collisions computation
- rx_dropped = rx_rrd_ov
- rx_over_errors = 0
- rx_missed_errors = 0

Improve tracing at the driver/core boundary
These patches add static tracpeoints at the driver/core boundary which
record various skb fields likely to be useful for datapath debugging.
On the TX side the boundary is where the core calls ndo_start_xmit, and
on the RX side it is where any of the various exported receive functions
is called.
The set of skb fields is mostly based on what I thought would be
interesting for sfc.
These patches are basically the same as what I sent as an RFC in
November, but rebased. They now depend on 'net: core: explicitly select
a txq before doing l2 forwarding', so please merge net into net-next

Both xen-netfront and xen-netback need to be able to set up the partial

header checksum in the process. This functionality is currently private
and duplicated between the two drivers.
Patch #1 of this series moves the implementation into the core network code
as there is nothing xen-specific about it and it is potentially useful to
any network driver.
Patch #2 removes the private implementation from netback.
Patch #3 removes the private implementation from netfront.

net: add skb_checksum_setup
This patch adds a function to set up the partial checksum offset for IP
packets (and optionally re-calculate the pseudo-header checksum) into the
core network code.
The implementation was previously private and duplicated between xen-netback
and xen-netfront, however it is not xen-specific and is potentially useful
to any network driver.

inet_diag: fix inet_diag_dump_icsk() to use correct state for timewait sockets
Fix inet_diag_dump_icsk() to reflect the fact that both TCP_TIME_WAIT
and TCP_FIN_WAIT2 connections are represented by inet_timewait_sock
(not just TIME_WAIT), and for such sockets the tw_substate field holds
the real state, which can be either TCP_TIME_WAIT or TCP_FIN_WAIT2.
This brings the inet_diag state-matching code in line with the field
it uses to populate idiag_state. This is also analogous to the info
exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state
and get_timewait4_sock() exports tw->tw_substate.
Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state
fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi
state time-wait" would also return sockets in state TCP_FIN_WAIT2.
This is an old bug that predates

====================
bonding: fix bond_3ad RCU usage
While digging through bond_3ad.c I've found that the RCU usage there is
just wrong - it's used as a kind of mutex/spinlock instead of RCU.
v3->v4: remove useless goto and wrap __get_first_agg() in proper RCU.
v2->v3: make bond_3ad_set_carrier() use RCU read lock for the whole
function, so that all other functions will be protected by RCU as well.
This way we can use _rcu variants everywhere.
v1->v2: use generic primitives instead of _rcu ones cause we can hold RTNL
lock without RCU one, which is still safe.
This patchset is on top of bond_3ad.c cleanup:
