[net-next 0/3] Intel Wired LAN Driver Updates

[net-next 0/3] Intel Wired LAN Driver Updates

[Aaron Brown]

This series contains updates to i40e from Shannon Nelson.  The first 
removes a mistaken file that I apparently introduced as part of a 
branch merge / update.  Second checks that descritors were allocated
before printing and makes the code a bit easier to read.  Finally he 
refines cloud support in the Firmware API.

Shannon Nelson (3): 
  i40e: remove mistaken file  
  i40e: check desc pointer before printing
  i40e: updates to AdminQ interface

[net-next 1/3] i40e: remove mistaken file

[Aaron Brown]

From: "Nelson, Shannon" <shannon.nelson@intel.com>

Remove the Module.symvers that somehow got caught up in 
commit 9d8bf54723e9f21c502a410495840d8771f769ef

[net-next 2/3] i40e: check desc pointer before printing

[Aaron Brown]

From: Shannon Nelson <shannon.nelson@intel.com>

Check that the descriptors were allocated before trying to dump
them to the logfile.  While we're there, de-trick-ify the code
so as to be easier to read and not abusing the types and unions.
