We're working on it, actually. Toke has been running some tests on
some beefy 100gbps hardware he recently acquired, and after v1 lands
we'll probably have a few interesting ideas for this.

+ RDMA and netdev folks
Sorry, to be late in the game, I don't see other patches, but from
the description below it seems like you are reinventing RDMA verbs
model. I have hard time to see the differences in the proposed
framework to already implemented in drivers/infiniband/* for the kernel
space and for the https://github.com/linux-rdma/rdma-core/ for the user
space parts.
Hard NAK from RDMA side.
Thanks

* [PATCH net-next 0/6] net: aquantia: add rx-flow filter support
From: Igor Russkikh @ 2018-11-12 15:02 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh
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 for L2 EtherType and PCP filters
* Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)
Dmitry Bogdanov (6):
net: aquantia: add rx-flow filter definitions
net: aquantia: add infrastructure for ntuple rules
net: aquantia: add support of L3/L4 ntuple filters
net: aquantia: add vlan id to rx flow filters
net: aquantia: add ethertype and PCP to rx flow filters
net: aquantia: add support of rx-vlan-filter offload

* [PATCH net-next 3/6] net: aquantia: add support of L3/L4 ntuple filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.
Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36
sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

* [PATCH net-next 4/6] net: aquantia: add vlan id to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.
Example:
To add a rule that directs packets from VLAN 2001 to queue 5:
ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 5 loc 0

* [PATCH net-next 5/6] net: aquantia: add ethertype and PCP to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.
Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

* [PATCH net-next 6/6] net: aquantia: add support of rx-vlan-filter offload
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Since it uses the same NIC table as rx flow vlan filter therefore
rx-flow vlan filter accepts only vlans that present on the interface
in case of rx-vlan-filter is on.

Hi David, please discard the patch, it seems it gets a conflict with just integrated 'net' tree.
Will resend it shortly.

* [PATCH net-next v2 0/6] net: aquantia: add rx-flow filter support
From: Igor Russkikh @ 2018-11-12 15:45 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh
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 for L2 EtherType and PCP filters
* Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)
Dmitry Bogdanov (6):
net: aquantia: add rx-flow filter definitions
net: aquantia: add infrastructure for ntuple rules
net: aquantia: add support of L3/L4 ntuple filters
net: aquantia: add vlan id to rx flow filters
net: aquantia: add ethertype and PCP to rx flow filters
net: aquantia: add support of rx-vlan-filter offload

* [PATCH net-next v2 3/6] net: aquantia: add support of L3/L4 ntuple filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.
Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36
sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

* [PATCH net-next v2 4/6] net: aquantia: add vlan id to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.
Example:
To add a rule that directs packets from VLAN 2001 to queue 5:
ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 5 loc 0

* [PATCH net-next v2 5/6] net: aquantia: add ethertype and PCP to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.
Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

* [PATCH net-next v2 6/6] net: aquantia: add support of rx-vlan-filter offload
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Since it uses the same NIC table as rx flow vlan filter therefore
rx-flow vlan filter accepts only vlans that present on the interface
in case of rx-vlan-filter is on.

* [PATCH net 1/5] net/smc: abort CLC connection in smc_release
From: Ursula Braun @ 2018-11-12 16:01 UTC (permalink / raw)
To: davem; +Cc: netdev, linux-s390, schwidefsky, heiko.carstens, raspl, ubraun
In-Reply-To: <20181112160133.16058-1-ubraun@linux.ibm.com>
From: Hans Wippel <hwippel@linux.ibm.com>
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.
This patch aborts a CLC connection when the respective non-blocking SMC
socket is released to avoid waiting on socket operations or timeouts.

* [PATCH net 4/5] net/smc: atomic SMCD cursor handling

Running uperf tests with SMCD on LPARs results in corrupted cursors.
SMCD cursors should be treated atomically to fix cursor corruption.

From: Ursula Braun <ursula.braun@linux.ibm.com>
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.
