[PATCH] IPMI: per-channel command registration

Browse source 
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.

For receiving commands, you have to individually register commands you
want to receive. Call ipmi_register_for_cmd() and supply the netfn
and command name for each command you want to receive. Only one user
may be registered for each netfn/cmd, but different users may register
for different commands.
and command name for each command you want to receive. You also
specify a bitmask of the channels you want to receive the command from
(or use IPMI_CHAN_ALL for all channels if you don't care). Only one
user may be registered for each netfn/cmd/channel, but different users
may register for different commands, or the same command if the
channel bitmasks do not overlap.
From userland, equivalent IOCTLs are provided to do these functions.
