When setting the PF interface up/down, notify the firmware to update
uplink state via MODIFY_VPORT_STATE, when E-Switch is enabled.
This behavior will prevent sending traffic out on uplink port when PF is
down, such as sending traffic from a VF interface which is still up.
Currently when calling mlx5e_open/close(), the driver only sends PAOS
command to notify the firmware to set the physical port state to
up/down, however, it is not sufficient. When VF is in "auto" state, it
follows the uplink state, which was not updated on mlx5e_open/close()
before this patch.
When switchdev mode is enabled and uplink representor is first enabled,
set the uplink port state value back to its FW default "AUTO".

net/mlx5: Add support in forward to namespace
{IB/net}/mlx5: Simplify don't trap code
net/mlx5: Replace zero-length array with flexible-array
Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

The patch sets the lag tx affinity of the data QPs and the GSI QPs
according to the LAG xmit slave.
For GSI QPs, in case the link layer is Ethenet (RoCE) we create two GSI
QPs, one for each physical port. When the driver selects the GSI QP, it
will consider the port affinity result. For connected QPs, the driver
sets the affinity of the xmit slave.
The above, ensures that RC QP and it's corresponding GSI QP will transmit
from the same physical port.

Until now the flex parser capability was used in ib_query_device() to
indicate tunnel_offloads_caps support for mpls_over_gre/mpls_over_udp.
Newer devices and firmware will have configurations with the flexparser
but without mpls support.
Testing for the flex parser capability was a mistake, the tunnel_stateless
capability was intended for detecting mpls and was introduced at the same
time as the flex parser capability.
Otherwise userspace will be incorrectly informed that a future device
supports MPLS when it does not.

Add HCA_CAP.egress_acl_forward_to_vport field to check whether HW
supports e-switch vport's egress acl to forward packets to other
e-switch vport or not.
By default E-Switch egress ACL forwards eswitch vports egress packets
to their corresponding NIC/VF vports.
With this cap enabled, the driver is allowed to alter this behavior
and forward packets to arbitrary NIC/VF vports with the following
limitations:
a. Multiple processing paths are supported if all of the following
conditions are met:
- HCA_CAP.egress_acl_forward_to_vport is set ==1.
- A destination of type Flow Table only appears once, as the
last destination in the list.
- Vport destination is supported if
HCA_CAP.egress_acl_forward_to_vport==1. Vport must not be
the Uplink.
b. Flow_tag not supported.
c. This table is only applicable after an FDB table is created.
d. Push VLAN action is not supported.
e. Pop VLAN action cannot be added concurrently to this table and
FDB table.
This feature will be used during port failover in bonding scenario
where two VFs representors are bonded to handle failover egress traffic
(VM's ingress/receive traffic).

Expose raw packet pacing APIs to be used by DEVX based applications.
The existing code was refactored to have a single flow with the new raw
APIs.
The new raw APIs considered the input of 'pp_rate_limit_context', uid,
'dedicated', upon looking for an existing entry.
This raw mode enables future device specification data in the raw
context without changing the existing logic and code.
The ability to ask for a dedicated entry gives control for application
to allocate entries according to its needs.
A dedicated entry may not be used by some other process and it also
enables the process spreading its resources to some different entries
for use different hardware resources as part of enforcing the rate.
The counter per entry was changed to be u64 to prevent any option to
overflow.

CQE checksum full mode in new HW, provides a full checksum of rx frame.
Covering bytes starting from eth protocol up to last byte in the received
frame (frame_size - ETH_HLEN), as expected by the stack.
Fixing up skb->csum by the driver is not required in such case. This fix
is to avoid wrong checksum calculation in drivers which already support
the new hardware with the new checksum mode.

When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.
This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.
This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued
by the HCA.

When ECPF eswitch manager is at offloads mode, it monitors functions
changed event from host PF side and acts according to the number of
VFs enabled/disabled.
As ECPF and host PF work in two independent hosts, it's possible that
host PF OS reboots but ECPF system is still kept on and continues
monitoring events from host PF. When kernel from host PF side is
booting, PCI iov driver does sriov_init and compute_max_vf_buses by
iterating over all valid num of VFs. This triggers FLR and generates
functions changed events, even though host PF HCA is not enabled at
this time. However, ECPF is not aware of this information, and still
handles these events as usual. ECPF system will see massive number of
reps are created, but destroyed immediately once creation finished.
To eliminate this noise, a bit is added to host parameter context to
indicate host PF is disabled. ECPF will not handle the VF changed
event if this bit is set.

Given a fw component index, the MCQI register allows us to query
this component's information (e.g. its version and capabilities).
Given a fw component index, the MCQS register allows us to query the
status of a fw component, including its type and state
(e.g. PRESET/IN_USE).
It can be used to find the index of a component of a specific type, by
sequentially increasing the component index, and querying each time the
type of the returned component.
If max component index is reached, 'last_index_flag' is set by the HCA.
These registers' description was added to query the running and pending
fw version of the HCA.

When a dual-port VHCA sends a RoCE packet on its non-native port, and
the packet arrives to its affiliated vport FDB, a mismatch might occur
on the rules that match the packet source vport. So we replace the
match on source port with the match on metadata that was configured in
ingress ACL, and that metadata will be passed further also to the NIC
RX table of the eswitch manager.
Introduce vport metadata matching bits and enum constants as a pre-step
towards metadata matching.
o metadata type C registers in the misc parameters 2 fields.
o esw_uplink_ingress_acl bit in esw cap. If it set, the device supports
ingress ACL for the uplink vport.
o fdb_to_vport_reg_* bits in flow table cap and esw vport context, to
support propagating the metadata to the nic rx through the loopback
path.
o flow_source in flow context, to indicate the known origin of packets.
o enum constants, to support the above bits.

For ECPF with eswitch manager privilege, query the host max VF count
by querying the device using query_functions command.
With this enhancement:
1. flow steering entries are created only for valid vports based on
the max VF count of the PF.
2. Driver only queries cap of valid vport.
Eswitch requires the max VFs when doing initialization, so do sr-iov
init before eswitch init.

To support sriov on a E-Switch manager, num_vfs are queried
to the firmware whenever E-Switch manager is notified by
esw_functions_changed event.
Replace host_params event with esw_functions_changed event that reflects
more appropriate naming.
While at it, also correct num_vfs type from int to u16 as expected by
the function mlx5_esw_query_functions().

Termination table is a flow table with a termination flag. The flag
allows the firmware to assume that the the specified actions are the last
actions list. This assumption allows the FW to safely perform potential
looping logic (e.g. hairpin). Introduce the bits for this attribute.
