However, when the statistics are disabled, the new instance in

brcmsmac: AP mode: update beacon when TIM changes

Beacons are not updated to reflect TIM changes. This is not compliant with
power-saving client stations as the beacons do not have valid TIM and can
cause the network to stall at random occasions and to have highly variable
latencies.
Fix it by updating beacon templates on mac80211 set_tim callback.

iwlwifi: mvm: check return value of rs_rate_from_ucode_rate()

The rs_rate_from_ucode_rate() function may return -EINVAL if the rate
is invalid, but none of the callsites check for the error, potentially
making us access arrays with index IWL_RATE_INVALID, which is larger
than the arrays, causing an out-of-bounds access.  This will trigger
KASAN warnings, such as the one reported in the bugzilla issue
mentioned below.

net/ipv6: Add knob to skip DELROUTE message on device down

Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE
notifications when a device is taken down (admin down) or deleted. IPv4
does not generate a message for routes evicted by the down or delete;
IPv6 does. A NOS at scale really needs to avoid these messages and have
IPv4 and IPv6 behave similarly, relying on userspace to handle link
notifications and evict the routes.

At this point existing user behavior needs to be preserved. Since
notifications are a global action (not per app) the only way to preserve
existing behavior and allow the messages to be skipped is to add a new
sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to
disable the notificatioons.

IPv6 route code already supports the option to skip the message (it is
used for multipath routes for example). Besides the new sysctl we need
to pass the skip_notify setting through the generic fib6_clean and
fib6_walk functions to fib6_clean_node and to set skip_notify on calls
to __ip_del_rt for the addrconf_ifdown path.
