Merge branch 'qed-enhancements-series'

Sudarsana Reddy Kalluru says:

====================
qed* enhancements series

The patch series add few enhancements to qed/qede drivers.

Changes from previous versions:
-------------------------------
v3: Revert v2 changes as the other paths (i.e. ptp) access the same data in
    atomic context.
v2: Use __set_bit()/__clear_bit() where data access doesn't need to be
    atomic.
====================
