Manish Rangankar ace7f46ba5 scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.
The QLogic FastLinQ Driver for iSCSI (qedi) is the iSCSI specific module
for 41000 Series Converged Network Adapters by QLogic.

This patch consists of following changes:

  - MAINTAINERS Makefile and Kconfig changes for qedi,
  - PCI driver registration,
  - iSCSI host level initialization,
  - Debugfs and log level infrastructure.

The following indiviual changes are merged into this commit:
