The hardware (MAC) LED blinking involves a few things: * Selecting which GPIO pins map to the MAC "power" and "network" lines; * Configuring the MAC LED state (associated, scanning, idle); * Configuring the MAC LED blinking type and speed. The AR5416 HAL configures the normal blinking setup - ie, blink rate based on TX/RX throughput. The default AR5212 HAL doesn't program in any specific blinking type, but the default of 0 is the same. This code introduces a few things: * The hardware led override is configured via sysctl 'hardled'; * The MAC network and power LED GPIO lines can be set, or left at -1 if needed. This is intended to allow only one of the hardware MUX entries to be configured (eg for PCIe cards which only have one LED exposed.) TODO: * For AR2417, the software LED blinking involves software blinking the Network LED. For the AR5416 and later, this can just be configured as a GPIO output line. I'll chase that up with a subsequent commit. * Add another software LED blink for "Link", separate from "activity", which blinks based on the association state. This would make my D-Link DWA-552 have consistent and useful LED behaviour (as they're marked "Link" and "Activity." * Don't expose the hardware LED override unless it's an AR5416 or later, as the previous generation hardware doesn't have this multiplexing setup. |
