[PATCH iwl-next v1 0/3] ice: add E825C device family support

[Grzegorz Nitka]

This patch series is supposed to add very basic support in ice driver
for new Intel Ethernet device family E825C.
E825C device consists of 2 NAC (Network Acceleration Complex) instances
in the IO die and supports max of 8 ports with combined bandwidth up to
200G.
There are 2 configurations (known as NAC Topology):
- single NAC (only one NAC is enabled) or
- dual NAC (both NACs are enabled, with one designated as primary and
  other as secondary).

This series covers:
- definition of new PCI device IDs assigned to E825C devices
- support for new 3k signed DDP segments

In the follow-up series support for new PHY and NAC topology parser
will be added.

Grzegorz Nitka (3):
  ice: introduce new E825C devices family
  ice:  Add helper function ice_is_generic_mac
  ice: add support for 3k signing DDP sections for E825C

[PATCH iwl-next v1 1/3] ice: introduce new E825C devices family

[Grzegorz Nitka]

Introduce new Intel Ethernet E825C family devices.
Add new PCI device IDs which are going to be supported by the
driver:
- 579C: Intel(R) Ethernet Connection E825-C for backplane
- 579D: Intel(R) Ethernet Connection E825-C for QSFP
- 579E: Intel(R) Ethernet Connection E825-C for SFP
- 579F: Intel(R) Ethernet Connection E825-C for SGMII

Add helper function ice_is_e825c() to verify if the running device
belongs to E825C family.

[PATCH iwl-next v1 2/3] ice: Add helper function ice_is_generic_mac

[Grzegorz Nitka]

E800 series devices have a couple of quirks:
1. Sideband control queues are not supported
2. The registers that the driver needs to program for the "Precision
   Time Protocol (PTP)" feature are different for E800 series devices
   compared to other devices supported by this driver.

Both these require conditional logic based on the underlying device we
are dealing with.

The function ice_is_sbq_supported added by commit 8f5ee3c477a8
("ice: add support for sideband messages") addresses (1).
The same function can be used to address (2) as well
but this just looks weird readability wise in cases that have nothing
to do with sideband control queues:

	if (ice_is_sbq_supported(hw))
		/* program register A */
	else
		/* program register B */

For these cases, the function ice_is_generic_mac introduced by this
patch communicates the idea/intention better. Also rework
ice_is_sbq_supported to use this new function.
As side-band queue is supported for E825C devices, it's mac_type is
considered as generic mac_type.

[PATCH iwl-next v1 3/3] ice: add support for 3k signing DDP sections for E825C

[Grzegorz Nitka]

E825C devices shall support the new signing type of RSA 3K for new DDP
section (SEGMENT_SIGN_TYPE_RSA3K_E825 (5) - already in the code).
The driver is responsible to verify the presence of correct signing type.
Add 3k signinig support for E825C devices based on mac_type:
ICE_MAC_GENERIC_3K_E825;
