[PATCH net-next 0/5] ionic: minor code updates

[Shannon Nelson]

These are a few updates to the ionic driver, mostly for handling
newer/faster QSFP connectors.

Brett Creeley (2):
  ionic: Use VLAN_ETH_HLEN when possible
  ionic: Translate IONIC_RC_ENOSUPP to EOPNOTSUPP

Shannon Nelson (3):
  ionic: add asic codes to firmware interface file
  ionic: add speed defines for 200G and 400G
  ionic: add support for QSFP_PLUS_CMIS

[PATCH net-next 1/5] ionic: add asic codes to firmware interface file

[Shannon Nelson]

Now that the firmware has learned how to properly report
the asic type id, add the values to our interface file.

The sharp-eyed reviewers will catch that the CAPRI value
changed here from 0 to 1.  This comes with the FW actually
defining it correctly.  This is safe for us to change as
nothing actually uses that value yet.

[PATCH net-next 2/5] ionic: Use VLAN_ETH_HLEN when possible

[Shannon Nelson]

From: Brett Creeley <brett.creeley@amd.com>

Replace when ETH_HLEN and VLAN_HLEN are used together with
VLAN_ETH_HLEN since it's the same value and uses 1 define
instead of 2.

[PATCH net-next 3/5] ionic: Translate IONIC_RC_ENOSUPP to EOPNOTSUPP

[Shannon Nelson]

From: Brett Creeley <brett.creeley@amd.com>

Instead of reporting -EINVAL when IONIC_RC_ENOSUPP is returned use
the -EOPNOTSUPP value. This aligns better since the FW only returns
IONIC_RC_ENOSUPP when operations aren't supported not when invalid
values are used.

You might consider refactoring the ionic driver to use the
ethtool_forced_speed_maps_init interface at some point. See 26c5334d344d
("ethtool: Add forced speed to supported link modes maps"), with
982b0192db45 ("ice: Refactor finding advertised link speed") and
1d4e4ecccb11 ("qede: populate supported link modes maps on module init")
(though it looks like the latter hasn't moved to the ethtool function).

This saves a bunch of text size on the module.

Yeah, and it would get rid of the silly CamelCase code complaints as 
well.  We'll have to take look at this in a future opportunity.

Patch looks fine, but this will only allow user space to decode page
00h. I suggest adding support for the get_module_eeprom_by_page()
ethtool operation in a follow-up patch, so that user space will be able
to query and decode more pages from the CMIS memory map.

Thanks, Ido, that's a good idea.  I'll have to talk to our firmware 
folks about making more of the module pages available to the driver.
