Add a timeout element to the DEVLINK_CMD_FLASH_UPDATE_STATUS
netlink message for use by a userland utility to show that
a particular firmware flash activity may take a long but
bounded time to finish. Also add a handy helper for drivers
to make use of the new timeout value.
UI usage hints:
- if non-zero, add timeout display to the end of the status line
[component] status_msg ( Xm Ys : Am Bs )
using the timeout value for Am Bs and updating the Xm Ys
every second
- if the timeout expires while awaiting the next update,
display something like
[component] status_msg ( timeout reached : Am Bs )
- if new status notify messages are received, remove
the timeout and start over

This patch adds mac80211 support to configure unsolicited

Changes include functions to store and retrieve probe response template,

[johannes: update the documentation to suit]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
The current API (which lets the driver turn on/off per vif directly) has a
number of limitations:
- it does not deal with AP_VLAN
- conditions for enabling (no tkip, no monitor) are only checked at
add_interface time
- no way to indicate 4-addr support
In order to address this, store offload flags in struct ieee80211_vif
(easy to extend for decap offload later). mac80211 initially sets the enable
flag, but gives the driver a chance to modify it before its settings are
applied. In addition to the .add_interface op, a .update_vif_offload op is
introduced, which can be used for runtime changes.
If a driver can't disable encap offload at runtime, or if it has some extra
limitations, it can simply override the flags within those ops.
Support for encap offload with 4-address mode interfaces can be enabled
by setting a flag from .add_interface or .update_vif_offload.

SOCK_QUEUE_SHRUNK is currently used by TCP as a temporary state
that remembers if some room has been made in the rtx queue
by an incoming ACK packet.
This is later used from tcp_check_space() before
considering to send EPOLLOUT.
Problem is: If we receive SACK packets, and no packet
is removed from RTX queue, we can send fresh packets, thus
moving them from write queue to rtx queue and eventually
empty the write queue.
This stall can happen if TCP_NOTSENT_LOWAT is used.
With this fix, we no longer risk stalling sends while holes
are repaired, and we can fully use socket sndbuf.
This also removes a cache line dirtying for typical RPC
workloads.

Change tcp_init_transfer() to only initialize congestion control if it
has not been initialized already.
With this new approach, we can arrange things so that if the EBPF code
sets the congestion control by calling setsockopt(TCP_CONGESTION) then
tcp_init_transfer() will not re-initialize the CC module.
This is an approach that has the following beneficial properties:
(1) This allows CC module customizations made by the EBPF called in
tcp_init_transfer() to persist, and not be wiped out by a later
call to tcp_init_congestion_control() in tcp_init_transfer().
(2) Does not flip the order of EBPF and CC init, to avoid causing bugs
for existing code upstream that depends on the current order.
(3) Does not cause 2 initializations for for CC in the case where the
EBPF called in tcp_init_transfer() wants to set the CC to a new CC
algorithm.
(4) Allows follow-on simplifications to the code in net/core/filter.c
and net/ipv4/tcp_cong.c, which currently both have some complexity
to special-case CC initialization to avoid double CC
initialization if EBPF sets the CC.

A devlink port may be for a controller consist of PCI device.
A devlink instance holds ports of two types of controllers.
(1) controller discovered on same system where eswitch resides
This is the case where PCI PF/VF of a controller and devlink eswitch
instance both are located on a single system.
(2) controller located on external host system.
This is the case where a controller is located in one system and its
devlink eswitch ports are located in a different system.
When a devlink eswitch instance serves the devlink ports of both
controllers together, PCI PF/VF numbers may overlap.
Due to this a unique phys_port_name cannot be constructed.
For example in below such system controller-0 and controller-1, each has
PCI PF pf0 whose eswitch ports can be present in controller-0.
These results in phys_port_name as "pf0" for both.
Similar problem exists for VFs and upcoming Sub functions.

On x86_64, each notification results in one skbuff allocation which
consumes at least 768 bytes due to the skbuff overhead.
This patch coalesces several notifications into one single skbuff, so
each notification consumes at least ~211 bytes, that ~3.5 times less
memory consumption. As a result, this is reducing the chances to exhaust
the netlink socket receive buffer.
Rule of thumb is that each notification batch only contains netlink
messages whose report flag is the same, nfnetlink_send() requires this
to do appropriate delivery to userspace, either via unicast (echo
mode) or multicast (monitor mode).
The skbuff control buffer is used to annotate the report flag for later
handling at the new coalescing routine.
The batch skbuff notification size is NLMSG_GOODSIZE, using a larger
skbuff would allow for more socket receiver buffer savings (to amortize
the cost of the skbuff even more), however, going over that size might
break userspace applications, so let's be conservative and stick to
NLMSG_GOODSIZE.

This dependency was added because ipv6_find_hdr was in iptables specific
code but is no longer required
Fixes: f8f626754ebe ("ipv6: Move ipv6_find_hdr() out of Netfilter code.")
