This series of patches improves connections setup and statistics.
This series is broken down as follows:
Patch 1 fixes the handling of connection setup failure in HW. Driver
shouldn't return success to tls_dev_add, until HW returns success.
Patch 2 avoids the log flood.
Patch 3 adds ktls statis

This patch added a new helper sk_stop_timer_sync, it deactivates a timer
like sk_stop_timer, but waits for the handler to finish.

This patch added the remove addr and subflow test cases and two new
functions.
The first function run_remove_tests calls do_transfer with two new
arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be
removed during the transfer process in namespace 1 and namespace 2.
If both
This patch added a new cfg, named cfg_remove in mptcp_connect. This new
cfg_remove is copied from cfg_join. The only difference between them is in
the do_rnd_write function. Here we slow down the transfer process of all
data to let the RM_ADDR suboption can be sent and received completely.
Otherwis
This patch added a new helper named mptcp_destroy_common containing the
shared code between mptcp_destroy() and mptcp_sock_destruct().

This patch added two new mibs for RM_ADDR, named MPTCP_MIB_RMADDR and
MPTCP_MIB_RMSUBFLOW, when the RM_ADDR suboption is received, increase
the first mib counter, when the local subflow is removed, increase the
second mib counter.

This patch implemented the local subflow removing function,
mptcp_pm_remove_subflow, it simply called mptcp_pm_nl_rm_subflow_received
under the PM spin lock.
We use mptcp_pm_remove_subflow to remove a local subflow, so change it's
argument from remote_id to local_id.

Series applied, thanks Florian.
This patch implements the remove announced addr and subflow logic in PM
netlink.
When the PM netlink removes an address, we traverse all the existing msk
sockets to find the relevant sockets.
We add a new list named anno_list in mptcp_pm_data, to record all the
announced addrs. In the traversing,
The re-check of pm->accept_subflow with pm->lock held was missing, this
patch fixed it.

This patch added the ADD_ADDR related mibs counter check function
chk_add_nr(). This function check both ADD_ADDR and ADD_ADDR with
echo flag.
The output looks like this:
07 unused signal address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - e
This patch added two mibs for ADD_ADDR, MPTCP_MIB_ADDADDR for receiving
of the ADD_ADDR suboption with echo-flag=0, and MPTCP_MIB_ECHOADD for
receiving the ADD_ADDR suboption with echo-flag=1.

When the ADD_ADDR suboption has been received, we need to send out the same
ADD_ADDR suboption with echo-flag=1, and no HMAC.

This patch added the RM_ADDR option parsing logic:
We parsed the incoming options to find if the rm_addr option is received,
and called mptcp_pm_rm_addr_received to schedule PM work to a new status,
named MPTCP_PM_RM_ADDR_RECEIVED.
PM work got this status, and called mptcp_pm_nl_rm_addr_received
