unnecessary Kconfig dependencies.

This patch adds support for the new backup port option that can be set
on a bridge port. If the port's carrier goes down all of the traffic
gets redirected to the configured backup port. We add the following new
arguments:
$ ip link set dev brport type bridge_slave backup_port brport2
$ ip link
Hello my dear.
Did you receive my email message to you? Please, get back to me ASAP as the
matter is becoming late. Expecting your urgent response.
Sean.
The timecounter needs to be updated at least once per ~550 seconds in
order to avoid a 40-bit SYSTIM timestamp to be misinterpreted as an old
timestamp.
Since commit 500462a9d ("timers: Switch to a non-cascading wheel"),
scheduling of delayed work seems to be less accurate and a requested
delay

Hi,
I am working on a self-written routing agent
(https://github.com/OLSR/OONF) and am stuck on a problem with netlink
that I cannot explain with an userspace error.
I am using a netlink socket for setting routes
(RTM_NEWROUTE/RTM_DELROUTE), querying the kernel for the current routes
in
I've been able to narrow the scope down, the issue is with macsec
itself. I setup two hosts with a macsec link between them, and let a
couple iperf3 sessions blast traffic across. At approximately 4.2
billion packets / 6TB data transferred one end stopped transmitting
packets. Doing a tcpdump

This patch should go to the stable trees starting with v4.8.
Thanks,

Commit 8d79266bc48c ("ip6_tunnel: add collect_md mode to IPv6
tunnels") introduced a check to avoid updating PMTU when
collect_md mode is enabled.
Later, commit f15ca723c1eb ("net: don't call update_pmtu
unconditionally") dropped this check, I guess inadvertently.
Restore it.
