| * qlge: Fix firmware mailbox command timeout.Ron Mercer2009-10-292-11/+13
| | | | | | | | | | | | | | | | | | The mailbox command process would only process a maximum of 5 unrelated firmware events while waiting for it's command completion status. It should process an unlimited number of events while waiting for a maximum of 5 seconds. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | TX completions were running in a workqueue queued by the ISR. This patch moves the processing of TX completions to an existing RSS NAPI context.

* qlge: Get rid of 'default' rx_ring type.Ron Mercer2009-08-284-64/+28
| | | | | | | | | | | | | | | | | | 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.

* qlge: Add/use function for link up/down.Ron Mercer2009-07-033-8/+26
| | | | | | | | | | | 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.

* qlge: Fix MAC address bonding issue.Ron Mercer2009-07-031-7/+43
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | RX buffer rings can be comprised of non-contiguous fixed size chunks of memory. The ring is given to the hardware as a pointer to a location that stores the location of the queue. If the queue is greater than 4096 bytes then the hardware gets a list of said pointers.
