Subject: [PATCH 2/2] be2net: Added functionality to support RoCE driver

From: Parav Pandit <parav.pandit@...lex.com>

- Increased MSIX vectors by 5 for RoCE traffic.
- Added macro to check roce support on a device.
- Added device specific doorbell, msix vector fields shared with nic functionality.
- Provides RoCE driver registration and deregistration functions.
- Added support functions which will be invoked on adapter
  add/remove and port up/down events.
- Traverses through the list of adapters for invoking callback functions
