For the lack of an official term to distinguish between the two formats, we can loosely categorize them by their fast ethernet or gigabit ethernet transceiver description. This patch creates the (driver-internal) Fast Ethernet Transceiver (FET) namespace and converts the 5906 EPHY definitions over.

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.

| | * | | | | | | mwl8k: fix firmware command serialisationLennert Buytenhek2009-08-20

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.
