Re: SDP: test bug 2027 and new error

[Amir Vadai <amirv-VPRAkNaXOzVS1MOuV/RT9w@public.gmane.org>]

Hi,

I think this is because sdp_add_device() require FMR to be supported.
I need to put a fix to disable ZCopy and not create FMR pool if doesn't
have support - I thought it would be part of BZ2027 fix.

As a workaround - you could comment out all the calls to
sdp_dev->fmr_pool. and make sure ZCopy is disabled by setting 0 in
sdp_zcopy_thresh.
