LSI/Broadcom sas9300/mpr pass through error

[Kevin Day]

I'm on FreeBSD 11.1-RELEASE with a SAS9300-8e card. Any time mprutil is invoked, the kernel logs:

mpr0: mpr_user_pass_thru: user reply buffer (64) smaller than returned buffer (68)

Attempting to use mprutil to do a firmware upgrade fails with:

mpr0: mpr_user_command: unsupported parameter or unsupported function in request (function = 0x9)



Is this a mismatch between driver/tools and firmware, or some other problem?
