bec5267cde net: devlink: extend port attrs for switch ID
Extend devlink_port_attrs_set() to pass switch ID for ports which are
part of switch and store it in port attrs. For other ports, this is
NULL.

Note that this allows the driver to group devlink ports into one or more
switches according to the actual topology.

c3f10cbcaa bnxt: call devlink_port_type_eth_set() before port register
Call devlink_port_type_eth_set() before devlink_port_register(). Bnxt
instances won't change type during lifetime. This avoids one extra
userspace devlink notification.

da203dfa89 Revert "devlink: Add a generic wake_on_lan port parameter"
This reverts commit b639583f9e.

As per discussion with Jakub Kicinski and Michal Kubecek,
this will be better addressed by soon-too-come ethtool netlink
API with additional indication that given configuration request
is supposed to be persisted.

Also, remove the parameter support from bnxt_en driver.

7c62cfb8c5 devlink: publish params only after driver init is done
Currently, user can do dump or get of param values right after the
devlink params are registered. However the driver may not be initialized
which is an issue. The same problem happens during notification
upon param registration. Allow driver to publish devlink params
whenever it is ready to handle get() ops. Note that this cannot
be resolved by init reordering, as the "driverinit" params have
to be available before the driver is initialized (it needs the param
values there).

782a624d00 bnxt_en: Add bnxt_en initial port params table and register it
Register devlink_port with devlink and create initial port params
table for bnxt_en. The table consists of a generic parameter:

wake_on_lan: Enables Wake on Lan for this port when magic packet
is received with this port's MAC address using ACPI pattern.
If enabled, the controller asserts a wake pin upon reception of
WoL packet.  ACPI (Advanced Configuration and Power Interface) is
an industry specification for the efficient handling of power
consumption in desktop and mobile computers.

v2->v3:
- Modify bnxt_dl_wol_validate(), to throw error message when user gives
  value other than DEVLINK_PARAM_WAKE_MAGIC ot to disable WOL.
- Use netdev_err() instead of netdev_warn(), when devlink_port_register()
  and devlink_port_params_register() returns error. Also, don't log rc
  in this message.

5fc7c12ffa bnxt_en: Remove unnecessary unsigned integer comparison and initialize variable
There is no need to compare *val.vu32* with < 0 because
such variable is of type u32 (32 bits, unsigned), making it
impossible to hold a negative value. Fix this by removing
such comparison.

Also, initialize variable *max_val* to -1, just in case
it is not initialized to either BNXT_MSIX_VEC_MAX or
BNXT_MSIX_VEC_MIN_MAX before using it in a comparison
with val.vu32 at line 159:

	if (val.vu32 > max_val)

f399e84978 bnxt_en: Use msix_vec_per_pf_max and msix_vec_per_pf_min devlink params.
This patch adds support for following generic permanent mode
devlink parameters. They can be modified using devlink param
commands.

msix_vec_per_pf_max - This param sets the number of MSIX vectors
that the device requests from the host on driver initialization.
This value is set in the device which limits MSIX vectors per PF.

msix_vec_per_pf_min - This param sets the number of minimal MSIX
vectors required for the device initialization. Value 0 indicates
a default value is selected. This value is set in the device which
limits MSIX vectors per PF.

8c95f773b4 bnxt_en: add support for Flower based vxlan encap/decap offload
This patch adds IPv4 vxlan encap/decap action support to TC-flower
offload.

For vxlan encap, the driver maintains a tunnel encap hash-table.
When a new flow with a tunnel encap action arrives, this table
is looked up; if an encap entry exists, it uses the already
programmed encap_record_handle as the tunnel_handle in the
hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the
L2 header fields are queried via a route lookup.
hwrm_cfa_encap_record_alloc cmd is used to create a new encap
record and the encap_record_handle is used as the tunnel_handle
while adding the flow.

For vxlan decap, the driver maintains a tunnel decap hash-table.
When a new flow with a tunnel decap action arrives, this table
is looked up; if a decap entry exists, it uses the already
programmed decap_filter_handle as the tunnel_handle in the
hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and
a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc
cmd. This handle is used as the tunnel_handle while adding the flow.

The code to issue the HWRM FW cmds is introduced in a follow-up patch.
