Merge branch 'qlcnic' 

Jitendra Kalsaria says:

====================
This set of patches has following updates:
* Enhanced channel configuration logs by adding logs for various cases.
* Take EPORT out of reset before disabling pause frame generation in the
  adapter.
* Add eSwitch statistics support in ethtool stats.
* Enable interrupt coalescing for 83xx adapter.
* Rename IRQ description.
* Added PCI_VENDOR_ID_QLOGIC, PCI_DEVICE_ID_QLOGIC_834X and PCI_DEVICE_ID_QLOGIC_824X
  for the patch "qlcnic: Add identifying string for 83xx adapter" as per Francois comment.
====================
