2009-08-26tg3: Preserve PCIe MPS setting for new devsMatt Carlson
Most older tg3 devices only supported a PCIe maximum payload size of 128 bytes. More recent devices bump this limit up to 256 bytes though. This patch modifies the code so that the MPS limit is only enforced on those devices that only allow the 128 byte setting.

2009-08-26tg3: Prevent tx BD corruptionMatt Carlson
This patch prevents a tx BD corruption bug by preventing the device from powering down the PLL from L1 if the link speed is 10Mbps or 100Mbps. The same bits are also used to prevent a system hang during chip reset resulting from a complicated set of events that ultimately leads to PCIe block register corruption.

2009-08-26netxen: bridged mode optimizationsNarender Kumar
When the interface is put in bridged mode, destination mac addresses are unknown to firmware. So packets take a slow path (lower priority) in firmware reducing performance. Firmware can cache limited number of remote unicast mac addresses for certain interval, if "dynamic mac learning" mode is enabled. Driver needs to enable this "mac learning" mode in firmware. Currently this is done through net device class sysfs entry, possibly this can also be done upon netlink notifications to from bridge.

2009-08-23RDS: Track transports via an array, not a listAndy Grover
Now that transports can be loaded in arbitrary order, it is important for rds_trans_get_preferred() to look for them in a particular order, instead of walking the list until it finds a transport that works for a given address. Now, each transport registers for a specific transport slot, and these are ordered so that preferred transports come first, and then if they are not loaded, other transports are queried.

2009-08-20mwl8k: fix firmware command serialisationLennert Buytenhek
The current mwl8k_priv->fw_lock spinlock doesn't actually protect against multiple commands being submitted at once, as it is not kept held over the entire firmware command submission. And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

Delete most of the mwl8k_work_struct fields and options, since most of them are unused or never changed from their defaults: - We always use priv->config_wq, so delete the wqueue argument from mwl8k_queue_work(). - MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all callers sleep for request completion, so sleep unconditionally. - MWL8K_WQ_FREE_WORKSTRUCT is never used. - MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally. - timeout_ms/txwait_attempts/tx_timeout_ms are never changed from their defaults, so just hardcode these in the workqueue worker. - step is never used.
