reorders the code hunks in what I believe was the intended sequence.

The 32-bit fields of a tx-wrb are little endian. The driver is currently
using be_dws_le_to_cpu() routine to swap (cpu to le) all the fields of
a tx-wrb. So, the rsvd field is also unnecessarily swapped.

This patch fixes this by individually swapping the required fields.
Also, the type of the fields in eth_tx_wrb{} is now changed to __le32
from u32 to avoid sparse warnings.

This patch adds support for processing the port misconfigure async

optical module is incorrectly installed or is faulty.

This patch also moves the port_name field to the adapter struct for
logging the event. As the be_cmd_query_port_name() call is now moved
to be_get_config(), it is modified to use the mailbox instead of MCCQ

While sending FW update cmds to the FW, the driver specifies the "type"
of each component that needs to be flashed. The FW then picks the offset
in the flash area at which the componnet is to be flashed. This doesn't work
when new components that the current FW doesn't recognize, need to be
flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein
the "offset" of the component in the flash area can be specified instead
of the "type". This patch uses the "offset" based FW-update mechanism and
only when it fails, it fallsback to the old "type" based update.

This change combines the reset and watchdog tasklets into a single task.

The advantage of this is that we can avoid multiple schedules of the reset
task when we have a reset event needed due to either the mailbox going down
or transmit packets being present on a link down.

This patch updates the ordering of the shutdown path so that we attempt to
shutdown the rings more gracefully. Basically the big changes are that we
shutdown the main Rx filter in the case of Rx and we set the carrier_off
state in the case of Tx so that packets stop being delivered from outside
the driver.  Then we shut down interrupts and NAPI.  Finally we stop the
rings from performing DMA and clean them.  This is a bit more graceful than
the previous path.
