0754d65bd4 ice: Add infrastructure for mqprio support via ndo_setup_tc
Add infrastructure required for "ndo_setup_tc:qdisc_mqprio".
ice_vsi_setup is modified to configure traffic classes based
on mqprio data received from the stack. This includes low-level
functions to configure min, max rate-limit parameters in hardware
for traffic classes. Each traffic class gets mapped to a hardware
channel (VSI) which can be individually configured with different
bandwidth parameters.

1d00032394 net/mlx5e: IPsec: Fix work queue entry ethernet segment checksum flags
Current Work Queue Entry (WQE) checksum (csum) flags in the ethernet
segment (eseg) in case of IPsec crypto offload datapath are not aligned
with PRM/HW expectations.

Currently the driver always sets the l3_inner_csum flag in case of IPsec
because of the wrong usage of skb->encapsulation as indicator for inner
IPsec header since skb->encapsulation is always ON for IPsec packets
since IPsec itself is an encapsulation protocol. The above forced a
failing attempts of calculating csum of non-existing segments (like in
the IP|ESP|TCP packet case which does not have an l3_inner) which led
to lots of packet drops hence the low throughput.

Fix by using xo->inner_ipproto as indicator for inner IPsec header
instead of skb->encapsulation in addition to setting the csum flags
as following:
* Tunnel Mode:
* Pkt: MAC  IP     ESP  IP    L4
* CSUM: l3_cs | l3_inner_cs | l4_inner_cs
*
* Transport Mode:
* Pkt: MAC  IP     ESP  L4
* CSUM: l3_cs [ | l4_cs (checksum partial case)]
*
* Tunnel(VXLAN TCP/UDP) over Transport Mode
* Pkt: MAC  IP     ESP  UDP  VXLAN  IP    L4
* CSUM: l3_cs | l3_inner_cs | l4_inner_cs

d10457f85d net/mlx5e: IPsec: Fix a misuse of the software parser's fields
IPsec crypto offload current Software Parser (SWP) fields settings in
the ethernet segment (eseg) are not aligned with PRM/HW expectations.
Among others in case of IP|ESP|TCP packet, current driver sets the
offsets for inner_l3 and inner_l4 although there is no inner l3/l4
headers relative to ESP header in such packets.

SWP provides the offsets for HW ,so it can be used to find csum fields
to offload the checksum, however these are not necessarily used by HW
and are used as fallback in case HW fails to parse the packet, e.g
when performing IPSec Transport Aware (IP | ESP | TCP) there is no
need to add SW parse on inner packet. So in some cases packets csum
was calculated correctly , whereas in other cases it failed. The later
faced csum errors (caused by wrong packet length calculations) which
led to lots of packet drops hence the low throughput.

Fix by setting the SWP fields as expected in a IP|ESP|TCP packet.

the following describe the expected SWP offsets:
* Tunnel Mode:
* SWP:      OutL3       InL3  InL4
* Pkt: MAC  IP     ESP  IP    L4
*
* Transport Mode:
* SWP:      OutL3       OutL4
* Pkt: MAC  IP     ESP  L4
*
* Tunnel(VXLAN TCP/UDP) over Transport Mode
* SWP:      OutL3                   InL3  InL4
* Pkt: MAC  IP     ESP  UDP  VXLAN  IP    L4

68e66e1a69 net/mlx5e: Fix vlan data lost during suspend flow
During suspend flow the driver calls mlx5e_destroy_vlan_table() which
does not only delete the vlans steering flow rules, but also frees the
data on currently active vlans, thus it is not restored during resume
flow.

This fix keeps the vlan data on suspend flow and frees it only on driver
remove flow.

14fe2471c6 net/mlx5: Lag, change multipath and bonding to be mutually exclusive
Both multipath and bonding events are changing the HW LAG state
independently.
Handling one of the features events while the other is already
enabled can cause unwanted behavior, for example handling
bonding event while multipath enabled will disable the lag and
cause multipath to stop working.

Fix it by ignoring bonding event while in multipath and ignoring FIB
events while in bonding mode.

2641b62d2f phy: micrel: ksz8041nl: do not use power down mode
Some Micrel KSZ8041NL PHY chips exhibit continuous RX errors after using
the power down mode bit (0.11). If the PHY is taken out of power down
mode in a certain temperature range, the PHY enters a weird state which
leads to continuously reporting RX errors. In that state, the MAC is not
able to receive or send any Ethernet frames and the activity LED is
constantly blinking. Since Linux is using the suspend callback when the
interface is taken down, ending up in that state can easily happen
during a normal startup.

Micrel confirmed the issue in errata DS80000700A [*], caused by abnormal
clock recovery when using power down mode. Even the latest revision (A4,
Revision ID 0x1513) seems to suffer that problem, and according to the
errata is not going to be fixed.

Remove the suspend/resume callback to avoid using the power down mode
completely.

receive buffers until it succeeds.

Now the allocation retry is added, it is unnecessary to do the rx
page allocation at the end of rx cleaning, so remove it. And reset

731797fdff net: hns3: add limit ets dwrr bandwidth cannot be 0
If ets dwrr bandwidth of tc is set to 0, the hardware will switch to SP
mode. In this case, this tc may occupy all the tx bandwidth if it has
huge traffic, so it violates the purpose of the user setting.

To fix this problem, limit the ets dwrr bandwidth must greater than 0.

b63fcaab95 net: hns3: reset DWRR of unused tc to zero
Currently, DWRR of tc will be initialized to a fixed value when this tc
is enabled, but it is not been reset to 0 when this tc is disabled. It
cause a problem that the DWRR of unused tc is not 0 after using tc tool
to add and delete multi-tc parameters.

For examples, after enabling 4 TCs and restoring to 1 TC by follow
tc commands:

$ tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3 0 1 2 3 queues \
  8@0 8@8 8@16 8@24 hw 1 mode channel
$ tc qdisc del dev eth0 root

Now there is just one TC is enabled for eth0, but the tc info querying by
debugfs is shown as follow:

$ cat /mnt/hns3/0000:7d:00.0/tm/tc_sch_info
enabled tc number: 1
weight_offset: 14
TC    MODE  WEIGHT
0     dwrr    100
1     dwrr    100
2     dwrr    100
3     dwrr    100
4     dwrr      0
5     dwrr      0
6     dwrr      0
7     dwrr      0

This patch fixes it by resetting DWRR of tc to 0 when tc is disabled.

9ca482a246 net: dsa: sja1105: parse {rx, tx}-internal-delay-ps properties for RGMII delays
This change does not fix any functional issue or address any real life
use case that wasn't possible before. It is just a small step in the
process of standardizing the way in which Ethernet MAC drivers may apply
RGMII delays (traditionally these have been applied by PHYs, with no
clear definition of what to do in the case of a fixed-link).

The sja1105 driver used to apply MAC-level RGMII delays on the RX data
lines when in fixed-link mode and using a phy-mode of "rgmii-rxid" or
"rgmii-id" and on the TX data lines when using "rgmii-txid" or "rgmii-id".
But the standard definitions don't say anything about behaving
differently when the port is in fixed-link vs when it isn't, and the new
device tree bindings are about having a way of applying the delays in a
way that is independent of the phy-mode and of the fixed-link property.

When the {rx,tx}-internal-delay-ps properties are present, use them,
otherwise fall back to the old behavior and warn.

One other thing to note is that the SJA1105 hardware applies a delay
value in degrees rather than in picoseconds (the delay in ps changes
depending on the frequency of the RGMII clock - 125 MHz at 1G, 25 MHz at
100M, 2.5MHz at 10M). I assume that is fine, we calculate the phase
shift of the internal delay lines assuming that the device tree meant
gigabit, and we let the hardware scale those according to the link speed.

55161e67d4 vrf: Revert "Reset skb conntrack connection..."
This reverts commit 09e856d54b.

When an interface is enslaved in a VRF, prerouting conntrack hook is
called twice: once in the context of the original input interface, and
once in the context of the VRF interface. If no special precausions are
taken, this leads to creation of two conntrack entries instead of one,
and breaks SNAT.

Commit above was intended to avoid creation of extra conntrack entries
when input interface is enslaved in a VRF. It did so by resetting
conntrack related data associated with the skb when it enters VRF context.

However it breaks netfilter operation. Imagine a use case when conntrack
zone must be assigned based on the original input interface, rather than
VRF interface (that would make original interfaces indistinguishable). One
could create netfilter rules similar to these:

        chain rawprerouting {
                type filter hook prerouting priority raw;
                iif realiface1 ct zone set 1 return
                iif realiface2 ct zone set 2 return
        }

This works before the mentioned commit, but not after: zone assignment
is "forgotten", and any subsequent NAT or filtering that is dependent
on the conntrack zone does not work.

Here is a reproducer script that demonstrates the difference in behaviour.

==========
#!/bin/sh

# This script demonstrates unexpected change of nftables behaviour
# caused by commit 09e856d54b ""vrf: Reset skb conntrack
# connection on VRF rcv"
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09e856d54bda5f288ef8437a90ab2b9b3eab83d1
#
# Before the commit, it was possible to assign conntrack zone to a
# packet (or mark it for `notracking`) in the prerouting chanin, raw
# priority, based on the `iif` (interface from which the packet
# arrived).
# After the change, # if the interface is enslaved in a VRF, such
# assignment is lost. Instead, assignment based on the `iif` matching
# the VRF master interface is honored. Thus it is impossible to
# distinguish packets based on the original interface.
#
# This script demonstrates this change of behaviour: conntrack zone 1
# or 2 is assigned depending on the match with the original interface
# or the vrf master interface. It can be observed that conntrack entry
# appears in different zone in the kernel versions before and after
# the commit.
