vtp bit in RX completion descriptor could be wrongly set in
some skews of BladEngine. Ignore this bit if vtm is not set.
Resending because the previous patch was against net-next tree.
This patch is against the net-2.6 tree.

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.
