Description Julien Cigar 2022-06-23 12:40:32 UTC 
Hello,

I'm running 13.1-RELEASE with ZFS on a Dell R340 with a "Dell HBA330 Adp (Embedded)" adapter (firmware version  16.17.01.00):

chimay% sudo pciconf -lv mpr0
mpr0@pci0:2:0:0:        class=0x010700 rev=0x02 hdr=0x00 vendor=0x1000 device=0x0097 subvendor=0x1028 subdevice=0x1f45
    vendor     = 'Broadcom / LSI'
    device     = 'SAS3008 PCI-Express Fusion-MPT SAS-3'
    class      = mass storage
    subclass   = SAS

It works well, but I noticed a lot of:

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

in the kernel logs

Is it an issue or is it harmless?

Thanks
