[PATCH] ipmi: add per-channel IPMB addresses
IPMI allows multiple IPMB channels on a single interface, and each channel might have a different IPMB address. However, the driver has only one IPMB address that it uses for everything. This patch adds new IOCTLS and a new internal interface for setting per-channel IPMB addresses and LUNs. New systems are coming out with support for multiple IPMB channels, and they are broken without this patch.
