Subject: [net-next 00/15][pull request] 100GbE Intel Wired LAN Driver Updates 2020-05-28

This series contains updates to the ice driver only.

Anirudh (Ani) adds a poll for reset completion before proceeding with
driver initialization when the DDP package fails to load and the firmware
issues a core reset.

Jake cleans up unnecessary code, since ice_set_dflt_vsi_ctx() performs a
memset to clear the info from the context structures.  Fixed a potential
double free during probe unrolling after a failure.  Also fixed a
potential NULL pointer dereference upon register_netdev() failure.

Tony makes two functions static which are not called outside of their
file.

Brett refactors the ice_ena_vf_mappings(), which was doing the VF's MSIx
and queue mapping in one function which was hard to digest.  So create a
new function to handle the enabling MSIx mappings and another function
to handle the enabling of queue mappings.  Simplify the code flow in
ice_sriov_configure().  Created a helper function for clearing
VPGEN_VFRTRIG register, as this needs to be done on reset to notify the
VF that we are done resetting it.  Fixed the initialization/creation and
reset flows, which was unnecessarily complicated, so separate the two
flows into their own functions.  Renamed VF initialization functions to
make it more clear what they do and why.  Added functionality to set the
VF trust mode bit on reset.  Added helper functions to rebuild the VLAN
and MAC configurations when resetting a VF.  Refactored how the VF reset
is handled to prevent VF reset timeouts.

Paul cleaned up code not needed during a CORER/GLOBR reset.

The following are changes since commit b113cabd4378ddd98dccdd7748a16f9f1f094ef0:
  sfc: avoid an unused-variable warning
