Staging: benet: remove driver now that it is merged in drivers/net/ 

The benet driver is now in the proper place in drivers/net/benet, so we
can remove the staging version.

* port by the BE's ARM firmware (assuming the standby port has link). In

This function initializes the be_net_object for subsequent
network operations.
Before calling this function, the driver must have allocated
space for the NetObject structure, initialized the structure,
allocated DMAable memory for all the network queues that form
part of the NetObject and populated the start address (virtual)
and number of entries allocated for each queue in the NetObject structure.
The driver must also have allocated memory to hold the
mailbox structure (MCC_MAILBOX) and post the physical address,
virtual addresses and the size of the mailbox memory in the
NetObj.mb_rd. This structure is used by BECLIB for
initial communication with the embedded MCC processor. BECLIB
uses the mailbox until MCC rings are created for more efficient
communication with the MCC processor.
If the driver wants to create multiple network interface for more
than one protection domain, it can call be_create_netobj()
multiple times once for each protection domain. A Maximum of
32 protection domains are supported.

Interrupt is asserted immediately after EQE

This routine creates an event queue based on the client completion
queue configuration information.
FunctionObject - Handle to a function object
EqBaseVa - Base VA for a the EQ ring
SizeEncoding - The encoded size for the EQ entries. This value is
either CEV_EQ_SIZE_4 or CEV_EQ_SIZE_16
NumEntries - CEV_CQ_CNT_* values.
Watermark - Enables watermark based coalescing. This parameter
must be of the type CEV_WMARK_* if watermarks
are enabled. If watermarks to to be disabled
this value should be-1.
TimerDelay - If a timer delay is enabled this value should be the
time of the delay in 8 microsecond units. If
delays are not used this parameter should be
set to -1.
ppEqObject - Internal EQ Handle returned.
Returns BE_SUCCESS if successfull,, otherwise a useful error code
is returned.
