Packets that are trapped via tc's trap action are currently subject to
the same policer as packets hitting local routes. The latter are
critical to the correct functioning of the control plane, while the
former are mainly used for traffic inspection.
Split the ACL trap to a separate group with its own policer. Use a
higher priority for these traps than for traps using mirror action
(e.g., ARP, IGMP). Otherwise, packets matching both traps will not be
forwarded in hardware (because of trap action) and also not forwarded in
software because they will be marked with 'offload_fwd_mark'.

The explicit mask and shift is not the appropriate way to parse fields
out of a little endian struct. The length field is internally __le16
and the strategy employed only happens to work on little endian machines
because the offset used is actually incorrect (length is at offset 6).
Also remove the related and no longer used definitions from bnxt.h.

We have logic to maintain network counters across resets by storing
the counters in bp->net_stats_prev before reset. But not all resets
will clear the counters. Certain resets that don't need to change
the number of rings do not clear the counters. The current logic
accumulates the counters before all resets, causing big jumps in
the counters after some resets, such as ethtool -G.
Fix it by only accumulating the counters during reset if the irq_re_init
parameter is set. The parameter signifies that all rings and interrupts
will be reset and that means that the counters will also be reset.

The commit da722186f654 (net: fec: set GPR bit on suspend by DT
configuration) set the GPR reigster offset and bit in driver for
wake on lan feature.
But it introduces two issues here:
- one SOC has two instances, they have different bit
- different SOCs may have different offset and bit
So to support wake-on-lan feature on other i.MX platforms, it should
configure the GPR reigster offset and bit from DT.
So the patch is to improve the commit da722186f654 (net: fec: set GPR
bit on suspend by DT configuration) to support multiple ethernet
instances on i.MX series.
v2:
* switch back to store the quirks bitmask in driver_data
v3:
* suggested by Sascha Hauer, use a struct fec_devinfo for
abstracting differences between different hardware variants,
it can give more freedom to describe the differences.

The driver uses a read polling mechanism to check the status of the MDIO
bus, to know if it is ready to accept next commands. This polling
mechanism uses usleep_delay() under the hood between reads which is fine
as long as high resolution timers are enabled. Otherwise the delays will
end up to be much longer than expected.
This patch fixes this by using udelay() under the hood when
CONFIG_HIGH_RES_TIMERS isn't enabled. This increases CPU usage.

The MSCC MIIM MDIO driver uses a waiting logic to wait for the MDIO bus
to be ready to accept next commands. It does so by polling the BUSY
status bit which indicates the MDIO bus has completed all pending
operations. This can take time, and the controller supports writing the
next command as soon as there are no pending commands (which happens
while the MDIO bus is busy completing its current command).
This patch implements this improved logic by adding an helper to poll
the PENDING status bit, and by adjusting where we should wait for the
bus to not be busy or to not be pending.

The MSCC MIIM MDIO driver uses delays to read poll a status register. I
made multiple tests on a Ocelot PCS120 platform which led me to reduce
those delays. The delay in between which the polling function is allowed
to sleep is reduced from 100us to 50us which in almost all cases is a
good value to succeed at the first retry. The overall delay is also
lowered as the prior value was really way to high, 10000us is large
enough.

The current MPLS dissector only parses the first MPLS Label Stack
Entry (second LSE can be parsed too, but only to set a key_id).
This patch adds the possibility to parse several LSEs by making
__skb_flow_dissect_mpls() return FLOW_DISSECT_RET_PROTO_AGAIN as long
as the Bottom Of Stack bit hasn't been seen, up to a maximum of
FLOW_DIS_MPLS_MAX entries.
FLOW_DIS_MPLS_MAX is arbitrarily set to 7. This should be enough for
many practical purposes, without wasting too much space.
To record the parsed values, flow_dissector_key_mpls is modified to
store an array of stack entries, instead of just the values of the
first one. A bit field, "used_lses", is also added to keep track of
the LSEs that have been set. The objective is to avoid defining a
new FLOW_DISSECTOR_KEY_MPLS_XX for each level of the MPLS stack.
TC flower is adapted for the new struct flow_dissector_key_mpls layout.
Matching on several MPLS Label Stack Entries will be added in the next
patch.
The NFP and MLX5 drivers are also adapted: nfp_flower_compile_mac() and
mlx5's parse_tunnel() now verify that the rule only uses the first LSE
and fail if it doesn't.
Finally, the behaviour of the FLOW_DISSECTOR_KEY_MPLS_ENTROPY key is
slightly modified. Instead of recording the first Entropy Label, it
now records the last one. This shouldn't have any consequences since
there doesn't seem to have any user of FLOW_DISSECTOR_KEY_MPLS_ENTROPY
in the tree. We'd probably better do a hash of all parsed MPLS labels
instead (excluding reserved labels) anyway. That'd give better entropy
and would probably also simplify the code. But that's not the purpose
of this patch, so I'm keeping that as a future possible improvement.

The dpaa-eth driver probes on compatible string for the MAC node, and
the fman/mac.c driver allocates a dpaa-ethernet platform device that
triggers the probing of the dpaa-eth net device driver.
All of this is fine, but the problem is that the struct device of the
dpaa_eth net_device is 2 parents away from the MAC which can be
referenced via of_node. So of_find_net_device_by_node can't find it, and
DSA switches won't be able to probe on top of FMan ports.
It would be a bit silly to modify a core function
(of_find_net_device_by_node) to look for dev->parent->parent->of_node
just for one driver. We're just 1 step away from implementing full
recursion.
Actually there have already been at least 2 previous attempts to make
this work:
- Commit a1a50c8e4c24 ("fsl/man: Inherit parent device and of_node")
- One or more of the patches in "[v3,0/6] adapt DPAA drivers for DSA":
https://patchwork.ozlabs.org/project/netdev/cover/1508178970-28945-1-git-send-email-madalin.bucur@nxp.com/
(I couldn't really figure out which one was supposed to solve the
problem and how).
Point being, it looks like this is still pretty much a problem today.
On T1040, the /sys/class/net/eth0 symlink currently points to
../../devices/platform/ffe000000.soc/ffe400000.fman/ffe4e6000.ethernet/dpaa-ethernet.0/net/eth0
which pretty much illustrates the problem. The closest of_node we've got
is the "fsl,fman-memac" at /soc@ffe000000/fman@400000/ethernet@e6000,
which is what we'd like to be able to reference from DSA as host port.
For of_find_net_device_by_node to find the eth0 port, we would need the
parent of the eth0 net_device to not be the "dpaa-ethernet" platform
device, but to point 1 level higher, aka the "fsl,fman-memac" node
directly. The new sysfs path would look like this:
../../devices/platform/ffe000000.soc/ffe400000.fman/ffe4e6000.ethernet/net/eth0
And this is exactly what SET_NETDEV_DEV does. It sets the parent of the
net_device. The new parent has an of_node associated with it, and
of_dev_node_match already checks for the of_node of the device or of its
parent.

The traffic class (TC) attribute of packet traps determines through which
TC a packet trap will be scheduled through the CPU port.
The priority attribute determines which trap will be triggered in case
several packet traps match a packet.
We try to configure these attributes to the same value for all packet
traps as there is little reason not to.
Some packet traps did not use the same value, so rectify that now.

As explained in commit 9ffcc3725f09 ("mlxsw: spectrum: Allow packets to
be trapped from any PG"), incoming packets can be admitted to the shared
buffer and forwarded / trapped, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Trapped packets are scheduled to transmission through the CPU port.
Currently, the minimum and maximum quotas of traffic class (TC) 0 of the
CPU port are 0, which means it is not usable.
Assign non-zero quotas to TC 0 of the CPU port, so that it could be
utilized by subsequent patches.

Reduce the default acceptable rate of DHCP packets to 128 packets per
second and reduce their priority. This is reasonable given the Spectrum
ASICs are limited to 128 ports at the moment.
These are only the default values. Users will be able to modify them via
devlink-trap.

Currently, IPv4 DHCP packets are trapped during L2 forwarding, which
means that packets might be trapped unnecessarily. Instead, only trap
the DHCP packets that reach the router. Either because they were flooded
to the router port or forwarded to it by the FDB. This is consistent
with the corresponding IPv6 trap.

Pull EFI fixes from Thomas Gleixner:
"A set of EFI fixes:
- Don't return a garbage screen info when EFI framebuffer is not
available
- Make the early EFI console work properly with wider fonts instead
of drawing garbage
- Prevent a memory buffer leak in allocate_e820()
- Print the firmware error record properly so it can be decoded by
users
- Fix a symbol clash in the host tool build which only happens with
newer compilers.
- Add a missing check for the event log version of TPM which caused
boot failures on several Dell systems due to an attempt to decode
SHA-1 format with the crypto agile algorithm"
