qlcnic: Mailbox refactoring

From: Himanshu Madhani <[email protected]>

This series contains following patches

o in v2 series, we received feedback on return codes to use standard error codes instead of mixing custom error codes. We have modified patch for loopback diagnostic test to return standard error codes.

o rest of the 3 patches in the series are for mailbox refactoring

Current driver-firmware mailbox interface was operating in polling mode because of some limitations with the earlier versions of 83xx adapter firmware. These issues are resolved now and we are implementing the mailbox interface in interrupt mode.

There are three patches which refactors mailbox handling:
* Interrupt mode mailbox implantation.
* Replace poll mode mailbox interfaces with interrupt mode interfaces.
* Operate mailbox in poll mode when interrupts are not available.

changes from v2 -> v3
* Addressed review feedback to use standard return codes for loopback diagnostic test.

Please consider applying these patches to net-next.

Thanks,
Himanshu
