Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2019-01-22

This series contains updates to i40e and xsk.

Jan exports xdp_get_umem_from_qid() for other drivers/modules to use.
Refactored the code use the netdev provided umems, instead of containing
them inside our i40e_vsi.

Aleksandr fixes an issue where RSS queues were misconfigured, so limit
the RSS queue number to the online CPU number.

Damian adds support for ethtool's setting and getting the FEC
configuration.

Grzegorz fixes a type mismatch, where the return value was not matching
the function declaration.

Sergey adds checks in the queue configuration handler to ensure the
number of queue pairs requested by the VF is less than maximum possible.

Lihong cleans up code left around from earlier silicon validation in the
i40e debugfs code.

Julia Lawall and Colin Ian King clean up white space indentation issues
found.
