Hi,
Here are some of my patches in order to fix WoL magic-packet on the current
macb driver.
I also add, in the second part of this series the feature to GEM types of IPs.
Please tell me if they should be separated; but the two last patches cannot go
without the 3 fixes first ones.
MACB and GEM code must co-exist and as they don't share exactly the same
register layout, I had to specialize a bit the suspend/resume paths and plug a
specific IRQ handler in order to avoid overloading the "normal" IRQ hot path.
The use of dumb buffers for RX that Harini implemented in [1] might
need to be considered for a follow-up patch series in order to address
lower-power modes on some of the platforms.
For instance, I didn't have to implement dumb buffers for some of the simpler
ARM9 platforms using MACB+FIFO types of controllers.
Please give feedback. Best regards,
Nicolas
