[PATCH] IPMI: per-channel command registration
This patch adds the ability to register for a command per-channel in the
IPMI driver.
If your BMC supports multiple channels, incoming messages can be useful to
have the ability to register to receive commands on a specific channel
instead the current behaviour of all channels.
