Himanshu Madhani says:

====================
qlcnic: Multiple Tx queue support and code refactoring

This Patch series contains following changes

o Refactored code to calculate, validate and assign Tx/SDS rings for  various modes of driver.
o Enhanced ethtool statistics for multi Tx queue on all supported adapters.
o Enable multiple Tx queue for 83xx and 84xx Series adapters.
o Register netdev for failed device state.

changes from v1 -> v2
o Dropped patch to replace inappropriate usage of kzalloc() with vzalloc().

Please apply to net-next.
