Breno Leitao 4f9a91c812 qlge: Only free resources if they were allocated
Currently qlge tries to release regions even if they were not allocated.
This causes messages like the following in the kernel log

Trying to free nonexistent resource <00000000006af400-00000000006af4ff>
Trying to free nonexistent resource <00003c04ff9f4000-00003c04ff9f7fff>
Trying to free nonexistent resource <00003c04ffc00000-00003c04ffcfffff>

This patch fixes the goto logic in order to not release the resources
if they were not allocated.

Ron Mercer b2014ff8ac qlge: Get rid of 'default' rx_ring type.
Currently we have three types of RX rings.

1) Default ring - services rx_ring for broadcast/multicast, handles
firmware events, and errors.

2) TX completion ring - handles only outbound completions.

3) RSS ring - handles only inbound completions.

This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring.  This makes better use of MSIX vectors since
they are a limited resource on some platforms.

Ron Mercer 7fab3bfe08 qlge: Fix MAC address bonding issue.
This addes functionality to set/clear the MAC address in the hardware
when the link goes up/down.
The MAC address register is persistent across function resets. In
bonding the same address can bounce from one port to the other.  This
can cause packets to be delivered to the wrong port.
This patch clears the MAC address in the hardware when the link is down
and sets it when the link comes up.
It was found that pulling/pushing the cable from one port to another
causes the same MAC address to be in both ports.
The next patch in this series will use this functionality as well.

Ron Mercer 709ac4f43d qlge: Fix bug in firmware event handler.
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.
