      i40e: use priv flags to control packet split · 827de392
      由 Jesse Brandeburg 提交于 
      Ethtool priv flags implementation to enable or disable packet split, which
is a hardware feature that inspects headers and will put headers in a
separate DMA buffer from the payload data.  The driver was automatically
choosing to enable packet split in some cases and this gives the user the
ability to turn it off/on explicitly.

to query state:
ethtool --show-priv-flags ethx

to enable:
ethtool --set-priv-flags ethx packet-split on
to disable:
ethtool --set-priv-flags ethx packet-split off

Why would anyone want this?
	Because some environments benefit from header/data split in the receive
	buffer, and the driver defaults to one or the other depending on
	environment/kernel parameters.

Why didn't you implement a generic ethtool control for this feature?
	Because Intel hardware is the only hardware that supports header/data
	split.

      i40e/i40evf: Refactor PHY structure and add phy_capabilities enum · fc72dbce
      由 Catherine Sullivan 提交于 
      Remove unused members in the PHY structure and add a new member to store
all the capabilities the PHY has as reported by the FW. This information
will help us determine what speeds the device is capable of when link is
down.

Also add an enum to decode the PHY types the NVM is capable of.
Use the phy_types variable to determine what phy types are possible
when link is down instead of device id as it will be more accurate.

When on a backplane device, we do not support changing any settings,
however we should display all the phy_types we are capable of so if we
see a backplane dev ID set supported and advertised purely based on
the phy_types variable.

      i40e/i40evf: Add module_types and update_link_info · 0a862b43
      由 Catherine Sullivan 提交于 
      Add a module_types variable to the link_info struct to save the module
information from get_phy_capabilities. This information can be used to
determine which speeds the module supports.

Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.

The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.

Use the new variable in ethtool to differentiate between a 10G/1G dual
speed fiber module and a 10G only module.
