The member subscribe should be per asoc, so that sockopt SCTP_EVENT
in the next patch can subscribe a event from one asoc only.

The member subscribe in sctp_sock is used to indicate to which of
the events it is subscribed, more like a group of flags. So it's
better to be defined as __u16 (2 bytpes), instead of struct
sctp_event_subscribe (13 bytes).
Note that sctp_event_subscribe is an UAPI struct, used on sockopt
calls,
sctp_event is a structure name defined in RFC for sockopt
SCTP_EVENT. To avoid the conflict, rename it.

Hi!
Our Qdisc offload so far has been very simplistic. We held
and array of marking thresholds and statistics sized to the
number of PF queues. This was sufficient since the only
configuration we supported was single layer of RED Qdiscs
(on top of MQ or not, but MQ isn't really about queuing).
Instead of writing the threshold out when Qdisc is configured
and not remembering it move to a scheme where we remember all
thresholds. When configuration changes parse the offloaded
Qdiscs and set thresholds appropriately.
This will help future extensions.

In preparation of handling more Qdisc types switch to a different

the driver. Every time the hierarchy changes parse it, and update

This issue happens when trying to add an existent tunnel. It
doesn't call sock_put() before returning -EEXIST to release
the sock refcnt that was held by calling sock_hold() before
the existence check.
This patch is to fix it by holding the sock after doing the
existence check.

This patchset mainly adds the Event Subscription sockopt described in
rfc6525#section-6.2:
Subscribing to events as described in [RFC6458] uses a setsockopt()
call with the SCTP_EVENT socket option. This option takes the
following structure, which specifies the association, the event type

SMC-D stress workload showed connection stalls. Since the firmware
decides to skip raising an interrupt if the SBA DMBE mask bit is
still set, this SBA DMBE mask bit should be cleared before the
IRQ handling in the SMC code runs. Otherwise there are small windows
possible with missing interrupts

In smc_wr_tx_put_slot() field pend->idx is used after being
cleared. That means always idx 0 is cleared in the wr_tx_mask.
This results in a broken administration of available WR send
payload buffers.

When a SMC-D link group is freed, a shutdown signal should be sent to
the peer to indicate that the link group is invalid. This patch adds the

When searching for an existing link group the queue pair number is also
to be taken into consideration. When the SMC server sends a new number
in a CLC packet (keeping all other values equal) then a new link group
is to be created on the SMC client side.

In case of a non-blocking SMC socket, the initial CLC handshake is
performed over a blocking TCP connection in a worker. If the SMC socket
is released, smc_release has to wait for the blocking CLC socket
operations (e.g., kernel_connect) inside the worker.

In this patchset the rx-flow filters functionality and vlan filter offloads
are implemented.
The rules in NIC hardware have fixed order and priorities.
To support this, the locations of filters from ethtool perspective are also
fixed:
* Locations 0 - 15 for VLAN ID filters
* Locations 16 - 31
