Get rid of spinlock and private mutex usage for exclusive access to the
HW semaphore register. rtnl_lock already creates exclusive access to
this register in all driver API.
Add rtnl to firmware worker threads that also use the HW semaphore register.

We need to set/clear the mac address register when the link goes up/down
respectively. Without this both ports of a 2-port device can end up
with the same mac address in a bonding scenario.
The new ql_link_on() and ql_link_off() will also be used in handling
certain firmware events.

Some firmware mailbox commands require the firmware to
communicate with the FCoE driver running on another
PCI function. This can potentially take several seconds.
This wait is done in process context only.

Since an FCoE function shares a port with this NIC function, the
jumbo settings must always be in place. This patch causes the
hardware to be set up for jumbo if it is not already done.

Each firmware mailbox command can have a different number of
valid data elements. When waiting for a mailbox command to
complete it the process passes it's element count and
waits for the completion. It is possible that while waiting
an unrelated firmware async event (AE) can arrive. When this
happens, the handler will over write the element count
with the value for the newly arrived AE. This can cause
the mailbox command to not get all of it's data.
This patch restores original mailbox count at the end
of the handler.

When the firmware is issuing events to the driver the events
must be removed from the queue. If the queue overflows, the
firmware will build and special event that captures those that
are lost.

This worker and it's supporting routines are used for
IDC 'inter-device-communication' events that require
an ACK mailbox command be sent to allow completion
of the request. These requests are originated by
another function wanting to change some common
port paramters. Typical example would be:
1) Change max TX/RX frame size allowed.
2) Change pause parameters.
3) Change loopback mode.

This patch adds functionality to get and set port parameters.
Currently it is used to set maximum TX/RX frame sizes. This process is
also capable of setting:
1) Pause type: Standard or Priority based.
2) Loop back mode.
3) Enable Jumbo frame mode (included here...)

This is not a logical change but rather a move of the inbound firmware event
handler into it's own function as it will later be called by the outbound
path.
The addition of the mutex is to create exclusive access to the mailbox
commands between inbound and outbound handling.
