Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2019-06-26

This series contains updates to ixgbe and i40e only.

Mauro S. M. Rodrigues update the ixgbe driver to handle transceivers who
comply with SFF-8472 but do not implement the Digital Diagnostic
Monitoring (DOM) interface.  Update the driver to check the necessary
bits to see if DOM is implemented before trying to read the additional
256 bytes in the EEPROM for DOM data.

Young Xiao fixes a potential divide by zero issue in ixgbe driver.

Aleksandr fixes i40e to recognize 2.5 and 5.0 GbE link speeds so that it
is not reported as "Unknown bps".  Fixes the driver to read the firmware
LLDP agent status during DCB initialization, and to properly log the
LLDP agent status to help with debugging when DCB fails to initialize.

Martyna fixes i40e for the missing supported and advertised link modes
information in ethtool.

Jake fixes a function header comment that was incorrect for a PTP
function in i40e.

Maciej fixes an issue for i40e when a XDP program is loaded the
descriptor count gets reset to the default value, resolve the issue by
making the current descriptor count persistent across resets.

Alice corrects a copyright date which she found to be incorrect.

Piotr adds a log entry when the traffic class 0 is added or deleted, which
was not being logged previously.

Gustavo A. R. Silva updates i40e to use struct_size() where possible.
