Commit e918c7bb authored by Paolo Abeni's avatar Paolo Abeni

Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================

This series contains updates to ice driver only.

Lukasz removes unnecessary argument from ice_fdir_comp_rules().

Jakub adds support for ethtool 'ether' flow-type rules.

Jake moves setting of VF MSI-X value to initialization function and adds
tracking of VF relative MSI-X index.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: store VF relative MSI-X index in q_vector->vf_reg_idx
  ice: set vf->num_msix in ice_initialize_vf_entry()
  ice: Implement 'flow-type ether' rules
  ice: Remove unnecessary argument from ice_fdir_comp_rules()
====================
