Merge branch 'qlcnic'

Himanshu Madhani says:

====================
qlcnic: Refactoring and enhancements for all adapters.

This patch series contains following patches.

o Enhanced debug data collection when we are in Tx-timeout situation.
o Enhanced MSI-x vector calculation for defualt load path as well
  as for TSS/RSS ring change path.
o Refactored interrupt coalescing code for all adapters.
o Refactored interrupt handling as well as cleanup of poll controller
  code patch for all adapters.
o changed rx_mac_learn type to boolean.

Please apply to net-next.
