Re: SAS3808 PCI-E 4.0, FreeBSD / ZFS support ?

Hi Ben,

SAS3808 & SAS3816 HBA cards supported through mpr driver. Broadcom supports
FreeBSD OS driver (i.e. mpr) only through inbox driver and hence users
won't be able to find the out-of-box driver (that we used to provide
earlier)  in the Broadcom's download site.

Thanks,
Sreekanth
