14074eab8d be2net: Patch to perform function reset at initialization
This patch is a bug fix to avoid system going into a bad state when
driver is loaded in context of kdump kernel. The patch fixes the issue
by performing a soft reset of pci function at probe time.

be_mbox_db_ring() has been changed to be_mbox_notify() (to be consistent with
be_mcc_notify()) and struct be_mcc_cq_entry changed to be_mcc_compl
to be consistent with rx/tx_compl.

8788fdc2a5 be2net: get rid of be_ctrl_info struct/abstraction
Currently only the be_ctrl_info struct ptr (instead of adapter) is
 passed to all the routines in be_cmds.c. Instead pass be_adapter
ptr to allow access to all its fields. Merge the contents of struct be_ctrl_info
into be_adapter. The resulting code is simpler.

6ac7b687cb be2net: Use MCC queue for cmds that may be called in BH context
Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context --
use the blocking MCC mbox to post cmds.
An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context.
So, these two cmds in BH context must use the MCC queue to post cmds.

5fb379ee67 be2net: Add MCC queue mechanism for BE cmds
Currenlty all cmds use the blocking MCC mbox to post cmds. An mbox cmd is protected
via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context. Instead cmds that may be
called in BH context must use the MCC queue to post cmds. The cmd completions
are rcvd in a separate completion queue and the events are placed in the tx-event
queue.
