(cherry picked from commit 1b5ea2e199)
The code for hostapd-mbedtls did not work when used for OWE association.
When handling association requests, the buffer offsets and length
assumptions were incorrect, leading to never calculating the y point,
thus denying association.
Also when crafting the association response, the buffer contained the
trailing key-type.
Fix up both issues to adhere to the specification and make
hostapd-mbedtls work with the OWE security type.

This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

hostapd's compile time option CONFIG_IEEE80211N was removed almost 3 years
ago, 80.211n/HT is always included since then.

As wolfSSL is having hard time maintaining ABI compatibility between
releases, we need to manually force rebuild of packages depending on
libwolfssl and thus force their upgrade. Otherwise due to the ABI
handling we would endup with possibly two libwolfssl libraries in the
system, including the patched libwolfssl-5.5.1, but still have
vulnerable services running using the vulnerable libwolfssl-5.4.0.
So in order to propagate update of libwolfssl to latest stable release
done in commit ec8fb542ec ("wolfssl: fix TLSv1.3 RCE in uhttpd by
using 5.5.1-stable (CVE-2022-39173)") which fixes several remotely
exploitable vulnerabilities, we need to bump PKG_RELEASE of all
packages using wolfSSL library.

19aae94 [build: avoid rebuilds of unset VARIANT packages] builds
packages defined without a VARIANT only once, using the first VARIANT
defined in the Makefile.
This caused problems with wpa-cli, as it is only built for variants that
include supplicant support, and the first VARIANT defined may not build
it.
The same happens to hostapd-utils, which is not built for
supplicant-only variants.
To circumvent this, set VARIANT=* for both packages so that they get
built for every defined variant. This should not cause spurious
rebuilds, since tey are not a dependency of any other package defined in
this Makefile.

Package hostapd-common is a dependency of every other package defined in
hostpad Makefile. It is currently built next to the bottom of that
Makefile's package list.
If you run make back to back, then check-compile will compare the
hostapd-common timestamp to the variant being compiled, to decide if the
varint needs to be rebuilt or not. Since the hostapd-conf package is
built towards the end of the list, it will be newer than most of the
variants, causing unnecessary package rebuilds.
Move it to the top, so that its timestamp will be older than dependent
packages, avoiding unnecessary rebuild of every selected variant.

issue as in the current fix contained in '130-wpa_supplicant-multi_ap_roam.patch',

nl80211_set_4addr_mode() could fail when trying to enable 4addr mode on
an interface that is in a bridge and has 4addr mode already enabled.
This operation would not have been necessary in the first place and this
failure results in disconnecting, e.g., when roaming from one backhaul

Set legacy_rates to 0 by default to disable 802.11b data rates by default.
The time has long come where 802.11b DSSS/CCK data rates should be disabled
by default in OpenWRT. Users in need of 802.11b client support can reasonably
enable these where they are needed.
The balance of equities has significantly, and for a long time, tipped
such that dropping backwards compatibility by default with 802.11b
devices is appropriate, proportionate and justified. By doing so,
management and control traffic is moved by default to a 20
MHz wide 6 Mb/s OFDM data rate instead of a 22 MHz wide 1 Mb/s DSSS data
rate. This is significantly more airtime efficient.
