Bump to the latest cake recipe.
This backports tc class support to kernel 4.9 and other than conditional
kernel compilation pre-processor macros represents the cake that has
gone upstream into kernel 4.19. Loud cheer!
Fun may be had by changing cake tin classification for packets on
ingress. e.g.
tc filter add dev ifb4eth0 parent 800b: protocol ip u32 match \
ip dport 6981 0xffff action skbedit priority 800b:1
Where 800b: represents the filter handle for the ifb obtained by 'tc
qdisc' and the 1 from 800b:1 represents the cake tin number. So the
above example puts all incoming packets destined for port 6981 into the
BULK (lowest priority) tin.

There has been recent significant activity with the cake qdisc of late
but in the cobalt branch. Some of that effort is related to upstreaming
to kernel & iproute2 mainline but we're not quite there yet. Relevant
feature changes:
ingress mode: Instead of only counting packets that make it past the
shaper, include packets we've decided to drop as well, since they did
arrive with us on the link and took link capacity.
This mode is more suitable for shaping the ingress of a link
(e.g. from ISP) rather than the more normal egress.
ptm mode: Minor optimisation in packet overhead calculation.
dual-src/dsthost/triple-isolate: Optimise only calculating src or dst
host hashes only if required.
ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in
highly assymetric links (downstream v upstream capacity) where the
majority of upstream link capacity is occupied with ACKS for downstream
traffic.
A separate iproute2 patch to teach it about Cake's new features will
follow.

Gracefully handle cases where the to-be-created wireless interface already
exists on the system which might commonly happen with non-multi-SSID capable
wireless drivers.
This fixes commit 8301e61365 which caused
previously ignored "Too many open files in system (-23)" errors to fail the
wireless setup procedure.
With the updated approach we'll still try recreating the vif after one
second if the first attempt to do so failed with ENFILE but we will now
consider the operation successfull if a second attempt still yields ENFILE
with the requested ifname already existing on the system.
Fixes FS#664, FS#704.

Keep them disabled by default to avoid pulling in extra kernel bloat
Signed-off-by: Felix Fietkau <nbd@nbd.name>
(cherry picked from commit 5afe9a054c)
In the drv_mac80211_setup function, mac80211_interface_cleanup
is called to ask the kernel to delete all existing interfaces
for the phy that is being configured via netlink.
Later in the first function, mac80211_prepare_vif is called to
set up the new interfaces as required.
But sometimes, when mac80211_prepare_vif (and so the relevant
`iw phy x interface add y` command) runs, the kernel might still
be cleaning up the old interface with the same ifname. It usually
takes very few time to do that; possibly a few milliseconds of
sleep in the script after detecting this error condition could be
enough, but the busybox sh does not support sub-second sleep
intervals.
When this happens, iw obviously fails to create the new interface;
and the following message is printed in the system log, followed by
subsequent failure messages from hostapd in case this would have been
an AP interface.

This was a long-standing issue existing since at least OpenWrt Backfire,
and today I finally managed to debug and (hopefully) solve it.
It was happening very few times on most devices; but it was happening
a lot more frequently on fast platforms with multiple radios, such as
the powerpc-based dual-ath9k-radio tl-wdr4900-v1.
