New Revision: 357651
URL: https://svnweb.freebsd.org/changeset/base/357651
Log:
Advertise the MPI Message Version that's contained in the IOCFacts message
in the sysctl block for the driver. mpsutil/mprutil needs this so it can
know how big of a buffer to allocate when requesting the IOCFacts from the
controller. This eliminates the kernel console messages about wrong
allocation sizes.
