====================
net: qualcomm: rmnet: Enable Mapv5

This series introduces the MAPv5 packet format.

   Patch 0 documents the MAPv4/v5.
   Patch 1 introduces the MAPv5 and the Inline checksum offload for RX/Ingress.
   Patch 2 introduces the MAPv5 and the Inline checksum offload for TX/Egress.

   A new checksum header format is used as part of MAPv5.For RX checksum offload,
   the checksum is verified by the HW and the validity is marked in the checksum
   header of MAPv5. For TX, the required metadata is filled up so hardware can
   compute the checksum.

   v1->v2:
   - Fixed the compilation errors, warnings reported by kernel test robot.
   - Checksum header definition is expanded to support big, little endian
           formats as mentioned by Jakub.

   v2->v3:
   - Fixed compilation errors reported by kernel bot for big endian flavor.

   v3->v4:
   - Made changes to use masks instead of C bit-fields as suggested by Jakub/Alex.

   v4->v5:
   - Corrected checkpatch errors and warnings reported by patchwork.

   v5->v6:
   - Corrected the bug identified by Alex and incorporated all his comments.

   v6->v7:
   - Removed duplicate inclusion of linux/bitfield.h in rmnet_map_data.c

   v7->v8:
   - Have addressed comments given by JAkub on v7 patches.
   - As suggested by Jakub, skb_cow_head() is used instead of expanding
     the head directly. This is now done in  rmnet_map_egress_handler().

Merge branch 'act_vlan-allow-modify-zero'

Boris Sukholitko says:

====================
net/sched: act_vlan: Fix modify to allow 0

Currently vlan modification action checks existence of vlan priority by
comparing it to 0. Therefore it is impossible to modify existing vlan
tag to have priority 0.

For example, the following tc command will change the vlan id but will
not affect vlan priority:

tc filter add dev eth1 ingress matchall action vlan modify id 300 \
        priority 0 pipe mirred egress redirect dev eth2

The incoming packet on eth1:

ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4

will be changed to:

ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4

although the user has intended to have p == 0.

The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params
and rely on it when deciding to set the priority.

The same flag is used to avoid dumping unset vlan priority.

Change Log:
v3 -> v4:
- revert tcf_vlan_get_fill_size change: total size calculation may race vs dump

v2 -> v3:
- Push assumes that the priority is being set
- tcf_vlan_get_fill_size accounts for priority existence

v1 -> v2:
- Do not dump unset priority and fix tests accordingly

net: dsa: sja1105: some table entries are always present when read dynamically

The SJA1105 has a static configuration comprised of a number of tables
with entries. Some of these can be read and modified at runtime as well,
through the dynamic configuration interface.

As a careful reader can notice from the comments in this file, the
software interface for accessing a table entry through the dynamic
reconfiguration is a bit of a no man's land, and varies wildly across
switch generations and even from one kind of table to another.

I have tried my best to come up with a software representation of a
'common denominator' SPI command to access a table entry through the
dynamic configuration interface:

struct sja1105_dyn_cmd {
bool search;
u64 valid; /* must be set to 1 */
u64 rdwrset; /* 0 to read, 1 to write */
u64 errors;
u64 valident; /* 0 if entry is invalid, 1 if valid */
u64 index;
};

Relevant to this patch is the VALIDENT bit, which for READ commands is
populated by the switch and lets us know if we're looking at junk or at
a real table entry.

In SJA1105, the dynamic reconfiguration interface for management routes
has notably not implemented the VALIDENT bit, leading to a workaround to
ignore this field in sja1105_dynamic_config_read(), as it will be set to
zero, but the data is valid nonetheless.

In SJA1110, this pattern has sadly been abused to death, and while there
are many more tables which can be read back over the dynamic config
interface compared to SJA1105, their handling isn't in any way more
uniform. Generally speaking, if there is a single possible entry in a
given table, and loading that table in the static config is mandatory as
per the documentation, then the VALIDENT bit is deemed as redundant and
more than likely not implemented.

So it is time to make the workaround more official, and add a bit to the
flags implemented by dynamic config tables. It will be used by more
tables when SJA1110 support arrives.

net: dsa: sja1105: always keep RGMII ports in the MAC role

In SJA1105, the xMII Mode Parameters Table field called PHY_MAC denotes
the 'role' of the port, be it a PHY or a MAC. This makes a difference in
the MII and RMII protocols, but RGMII is symmetric, so either PHY or MAC
settings result in the same hardware behavior.

The SJA1110 is different, and the RGMII ports only work when configured
in MAC mode, so keep the port roles in MAC mode unconditionally.

Why we had an RGMII port in the PHY role in the first place was because
we wanted to have a way in the driver to denote whether RGMII delays
should be applied based on the phy-mode property or not. This is already
done in sja1105_parse_rgmii_delays() based on an intermediary
struct sja1105_dt_port (which contains the port role). So it is a
logical fallacy to use the hardware configuration as a scratchpad for
driver data, it isn't necessary.

We can also remove the gating condition for applying RGMII delays only
for ports in the PHY role. The .setup_rgmii_delay() method looks at
the priv->rgmii_rx_delay[port] and priv->rgmii_tx_delay[port] properties
which are already populated properly (in the case of a port in the MAC
role they are false). Removing this condition generates a few more SPI
writes for these ports (clearing the RGMII delays) which are perhaps
useless for SJA1105P/Q/R/S, where we know that the delays are disabled
by default. But for SJA1110, the firmware on the embedded microcontroller
might have done something funny, so it's always a good idea to clear the
RGMII delays if that's what Linux expects.

net: dsa: sja1105: add a PHY interface type compatibility matrix

On the SJA1105, all ports support the parallel "xMII" protocols (MII,
RMII, RGMII) except for port 4 on SJA1105R/S which supports only SGMII.
This was relatively easy to model, by special-casing the SGMII port.

On the SJA1110, certain ports can be pinmuxed between SGMII and xMII, or
between SGMII and an internal 100base-TX PHY. This creates problems,
because the driver's assumption so far was that if a port supports
SGMII, it uses SGMII.

We allow the device tree to tell us how the port pinmuxing is done, and
check that against a PHY interface type compatibility matrix for
plausibility.

The other big change is that instead of doing SGMII configuration based
on what the port supports, we do it based on what is the configured
phy_mode of the port.

The 2500base-x support added in this patch is not complete.

can look at the xMII Mode Parameters Table which already holds that

But with the SJA1110, we cannot make the distinction between sgmii and

appears odd that the address accessed through indirection still
references the base address from the SJA1105S register map (first MDIO
register is at 0x1f0000), when it could index the SGMII registers
starting from zero.

Except that the 0x1f0000 is not a base address at all, it seems. It is
0x1f << 16 | 0x0000, and 0x1f is coding for the vendor-specific MMD2.
So, it turns out, the Synopsys PCS implements all its registers inside
the vendor-specific MMDs 1 and 2 (0x1e and 0x1f). This explains why the
PCS has no overlaps (for the other MMDs) with other register regions of
the switch (because no other MMDs are implemented).

Change the code to remove the SGMII "base address" and explicitly encode
the MMD for reads/writes. This will become necessary for SJA1110 support.

net: dsa: sja1105: allow SGMII PCS configuration to be per port

The SJA1105 R and S switches have 1 SGMII port (port 4). Because there
is only one such port, there is no "port" parameter in the configuration
code for the SGMII PCS.

However, the SJA1110 can have up to 4 SGMII ports, each with its own
SGMII register map. So we need to generalize the logic.

ipv6: use prandom_u32() for ID generation

This is a complement to commit aa6dd211e4b1 ("inet: use bigger hash
table for IP ID generation"), but focusing on some specific aspects
of IPv6.

Contary to IPv4, IPv6 only uses packet IDs with fragments, and with a
minimum MTU of 1280, it's much less easy to force a remote peer to
produce many fragments to explore its ID sequence. In addition packet
IDs are 32-bit in IPv6, which further complicates their analysis. On
the other hand, it is often easier to choose among plenty of possible
source addresses and partially work around the bigger hash table the
commit above permits, which leaves IPv6 partially exposed to some
possibilities of remote analysis at the risk of weakening some
protocols like DNS if some IDs can be predicted with a good enough
probability.

Given the wide range of permitted IDs, the risk of collision is extremely
low so there's no need to rely on the positive increment algorithm that
is shared with the IPv4 code via ip_idents_reserve(). We have a fast
PRNG, so let's simply call prandom_u32() and be done with it.

Performance measurements at 10 Gbps couldn't show any difference with
the previous code, even when using a single core, because due to the
large fragments, we're limited to only ~930 kpps at 10 Gbps and the cost
of the random generation is completely offset by other operations and by
the network transfer time. In addition, this change removes the need to
update a shared entry in the idents table so it may even end up being
slightly faster on large scale systems where this matters.

The risk of at least one collision here is about 1/80 million among
10 IDs, 1/850k among 100 IDs, and still only 1/8.5k among 1000 IDs,
which remains very low compared to IPv4 where all IDs are reused
every 4 to 80ms on a 10 Gbps flow depending on packet sizes.
