Re: How to use bioctl with mpt?

[Dima Veselov <kab00m%lich.phys.spbu.ru@localhost>]

I have no deep knowledge of NetBSD code, but I use
lot of servers in production with LSI 1064 and 1068.
I think mpt driver lack real support for RAID management
on these chips, Unknown async events are proving that.
I may be wrong but I have no cases where RAID was
managed through bio and mpt.
