fa38860c5e nl80211: Fix build with libnl 1.1
Commit 630b3230c8 ('nl80211: Increase
netlink receive buffer size') added unconditional use of
nl_socket_set_buffer_size() which was not included in libnl 1.1. Fix use
of that old version by making this conditional on CONFIG_LIBNL20.

630b3230c8 nl80211: Increase netlink receive buffer size
libnl uses a pretty small buffer (32 kB that gets converted to 64 kB) by
default. It is possible to hit that limit in some cases where operations
are blocked, e.g., with a burst of Deauthentication frames to hostapd
and STA entry deletion. Try to increase the buffer to make this less
likely to occur.

5a2a6de6a5 mesh: Make inactivity timer configurable
Current mesh code uses ap_max_inactivity as inactivity timer. This patch
makes it configurable.

There is another mesh inactivity timer in mac80211. The timer works even
if user_mpm=1. So this patch sets the max value to the timer for
workaround.

1fef85c7c5 nl80211: Fix AP-scan-in-STA-mode error path behavior
If a second scan trigger attempt fails in STA mode, the error path was
supposed to restore the old mode that was in use before changing to STA
mode. However, wpa_driver_nl80211_set_mode() changes drv->nlmode on
success, so the recovery path needs to use the saved old_mode value
instead.

d58ade2121 nl80211: Fix compilation with libnl 1.1 and 2.0
Unfortunately, libnl 3.0 has changed the API in a way that is not
backwards compatible by renaming nlmsg_len() to nlmsg_datalen() without
leaving the older nlmsg_len() defined. As such, there does not seem to
be any clean way of using this function without breaking the build with
some libnl versions. For now, replace this call with direct calculation
of the data length since it can be done with a simple one-liner that
compiles with all libnl versions.

are other ways of detecting and working around state mismatches with the
