Subject: [PATCH/RFC v2] leds: trigger: Introduce a NETDEV trigger

From: Ben Whitten <ben.whitten@...il.com>

The patch was converted to led_blink_oneshot, in doing so we find that the
behaviour has changed. As I dont want to break 'userspace' led behaviour this
patch shouldn't be merged as is. Open to suggestions.

Given an interval of 50ms and heavy throughput, the previous implementation
produced a blink with 100ms period and 50% dutycycle. The led_blink_oneshot
version produces a blink with 140ms period and 57% dutycycle.
I assume a fudge factor on the oneshot delay to bring the period back to 100ms
would be device specific so not suitable.

Kind regards,
