All cmds issued to BE after the creation of mccq must now use the mcc-q
(and not mbox) to avoid a hw issue that results in mbox poll timeout.

Changes to support flashing of the be2 network adapter using the
request_firmware() & ethtool infrastructure. The trigger to flash the device
will come from ethtool utility. The driver will invoke request_firmware()
to start the flash process. The file containing the flash image is expected
to be available in /lib/firmware/

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.

While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames.
With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[].
Now we coalesce the frags from the same physical page into one slot in
skb_shinfo(skb)->frags[] and go to the next index when the frag is from
different physical page.
This patch is against the net-2.6 tree.

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.
