This is part of "moving things to l2cap_chan". As one the first move it

struct l2cap_chan cames to create a clear separation between what
properties and data belongs to the L2CAP channel and what belongs to the
socket. By now we just fold the struct sock * in struct l2cap_chan as all
the channel info is struct l2cap_pinfo today.
In the next commits we will see a move of channel stuff to struct
l2cap_chan.

The description for buf_size was misleading and
just said you couldn't TX larger aggregates, but
of course you can't TX aggregates in a way that
would exceed the window either, which is possible
even if the aggregates are shorter than that.

explaining this to me.

This patch adds automated creation of the local EIR data based on what
16-bit UUIDs are registered and what the device name is. This should
cover the majority use cases, however things like 32/128-bit UUIDs, TX
power and Device ID will need to be added later to be on par with what
bluetoothd is capable of doing (without the Management interface).

This patch adds the name of the adapter to the reply of the read_info

The management messages reserve 249 bytes for the name instead of 248

My commit 6d55cb91a0 (gre: fix hard header destination
address checking) broke multicast.
The reason is that ip_gre used to get ipgre_header() calls with
zero destination if we have NOARP or multicast destination. Instead
the actual target was decided at ipgre_tunnel_xmit() time based on
per-protocol dissection.
Instead of allowing the "abuse" of ->header() calls with invalid
destination, this creates multicast mappings for ip_gre. This also
fixes "ip neigh show nud noarp" to display the proper multicast
mappings used by the gre device.

and the preplay_esn pointers to the state if we use the
new replay detection method. To this end, we add a

the replay detection and takes over the necessary values

commit fd245a4adb (net_sched: move TCQ_F_THROTTLED flag)
added a race.
qdisc_watchdog() is run from softirq, so special care should be taken or
we can lose one state transition (THROTTLED/RUNNING)
Prior to fd245a4adb, we were manipulating q->flags (qdisc->flags &=
~TCQ_F_THROTTLED;) and this manipulation could only race with
qdisc_warn_nonwc().
Since we want to avoid atomic ops in qdisc fast path - it was the
meaning of commit 3711210576 (QDISC_STATE_RUNNING dont need atomic
bit ops) - fix is to move THROTTLE bit into 'state' field, this one
being manipulated with SMP and IRQ safe operations.

Alex Sidorenko reported for problems with local
routes left after IP addresses are deleted. It happens
when same IPs are used in more than one subnet for the
device.
Fix fib_del_ifaddr to restrict the checks for duplicate
local and broadcast addresses only to the IFAs that use
our primary IFA or another primary IFA with same address.
And we expect the prefsrc to be matched when the routes
are deleted because it is possible they to differ only by
prefsrc. This patch prevents local and broadcast routes
to be leaked until their primary IP is deleted finally
from the box.
As the secondary address promotion needs to delete
the routes for all secondaries that used the old primary IFA,
add option to ignore these secondaries from the checks and
to assume they are already deleted, so that we can safely
delete the route while these IFAs are still on the device list.
