ddc7834af8 rxrpc: Fix loss of final ack on shutdown
Fix the loss of transmission of a call's final ack when a socket gets shut
down.  This means that the server will retransmit the last data packet or
send a ping ack and then get an ICMP indicating the port got closed.  The
server will then view this as a failure.

Willy Tarreau says:

====================
macb: support the 2-deep Tx queue on at91

while running some tests on my Breadbee board, I noticed poor network
Tx performance. I had a look at the driver (macb, at91ether variant)
and noticed that at91ether_start_xmit() immediately stops the queue
after sending a frame and waits for the interrupt to restart the queue,
causing a dead time after each packet is sent.

The AT91RM9200 datasheet states that the controller supports two frames,
one being sent and the other one being queued, so I performed minimal
changes to support this. The transmit performance on my board has
increased by 50% on medium-sized packets (HTTP traffic), and with large
packets I can now reach line rate.

Since this driver is shared by various platforms, I tried my best to
isolate and limit the changes as much as possible and I think it's pretty
reasonable as-is. I've run extensive tests and couldn't meet any
unexpected situation (no stall, overflow nor lockup).

There are 3 patches in this series. The first one adds the missing
interrupt flag for RM9200 (TBRE, indicating the tx buffer is willing
to take a new packet). The second one replaces the single skb with a
2-array and uses only index 0. It does no other change, this is just
to prepare the code for the third one. The third one implements the
queue. Packets are added at the tail of the queue, the queue is
stopped at 2 packets and the interrupt releases 0, 1 or 2 depending
on what the transmit status register reports.

0a4e9ce17b macb: support the two tx descriptors on at91rm9200
The at91rm9200 variant used by a few chips including the MSC313 supports
two Tx descriptors (one frame being serialized and another one queued).
However the driver only implemented a single one, which adds a dead time
after each transfer to receive and process the interrupt and wake the
queue up, preventing from reaching line rate.

This patch implements a very basic 2-deep queue to address this limitation.
The tests run on a Breadbee board equipped with an MSC313E show that at
1 GHz, HTTP traffic on medium-sized objects (45kB) was limited to exactly
50 Mbps before this patch, and jumped to 76 Mbps with this patch. And tests
on a single TCP stream with an MTU of 576 jump from 10kpps to 15kpps. With
1500 byte packets it's now possible to reach line rate versus 75 Mbps
before.

73d7422813 macb: prepare at91 to use a 2-frame TX queue
The RM9200 supports one frame being sent while another one is waiting in
queue. This avoids the dead time that follows the emission of a frame
and which prevents one from reaching line speed.

Right now the driver supports only a single skb, so we'll first replace
the rm9200-specific skb info with an array of two macb_tx_skb (already
used by other drivers). This patch only moves the skb_length to
txq[0].size and skb_physaddr to skb[0].mapping but doesn't perform any
other change. It already uses [desc] in order to minimize future changes.

5be019040c net/mlx5e: IPsec: Add Connect-X IPsec Tx data path offload
In the TX data path, spot packets with xfrm stack IPsec offload
indication.

Fill Software-Parser segment in TX descriptor so that the hardware
may parse the ESP protocol, and perform TX checksum offload on the
inner payload.

Support GSO, by providing the trailer data and ICV placeholder
so HW can fill it post encryption operation.

Padding alignment cannot be performed in HW (ConnectX-6Dx) due to
a bug. Software can overcome this limitation by adding NETIF_F_HW_ESP to
the gso_partial_features field in netdev so the packets being
aligned by the stack.

l4_inner_checksum cannot be offloaded by HW for IPsec tunnel type packet.

Note that for GSO SKBs, the stack does not include an ESP trailer,
unlike the non-GSO case.

Below is the iperf3 performance report on two server of 24 cores
Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz with ConnectX6-DX.
All the bandwidth test uses iperf3 TCP traffic with packet size 128KB.
Each tunnel uses one iperf3 stream with one thread (option -P1).
TX crypto offload shows improvements on both bandwidth
and CPU utilization.

Regression tests show no degradation on non-ipsec and
non-offload-ipsec traffics. The packet rate test uses pktgen UDP to
transmit on single CPU, the instructions and cycles are measured on
the transmit CPU.

Currently the error exit path err_free kfree's attr. In the case where
flow and parse_attr failed to be allocated this return path will free
the uninitialized pointer attr, which is not correct.  In the other
case where attr fails to allocate attr does not need to be freed. So
in both error exits via err_free attr should not be freed, so remove
it.
