Hi all,
This patch series adds support for allowing Wake-on-LAN to wake-up the
system using configurable filters. This is particular useful in the context
of Android where wake on MDNS is a requirement.
We support this by using the bcm_sf2 Compact Field Processor (CFP) which
supports matching packets and tagging them with an unique identifier
(Classification ID) that is added in each packet being matched through the use
of Broadcom tags. The SYSTEMPORT MAC attached to that switch is then used to
match that unique identifier and trigger a system wake-up event.
Last patch is the ethtool modifications to support that feature.
Example:
ethtool --config-nfc gphy flow-type udp4 src-ip 192.168.1.1 dst-ip 192.168.1.32
\
src-port 1234 dst-port 5678 action 64
Added rule with ID 1
ethtool -s gphy wol f filters 0x2
To wake up the device:
nc -vz -u -p 1234 -s 192.168.1.1 192.168.1.32 5678
