I'm at a loss on how to get the hex address to go underneath acls when
setting up srpt. If I use the fe80 prefix I see everywhere including
/sys, it gets rejected. If I use the prefix shown in the kernel
rejection method, which I can't find anywhere else, it works fine.
I am using targetcli, but
I think:
TL;DR - I can find my initiator's guid, but targetcli doesn't work
with that in acls. I have to give it the i_port_id to work. How do I
find the i_port_id, other than having a failed connection attempt and
looking at dmesg?

Use the flags originally provided for hfi1 in the rdmavt driver. These will
be made available to drivers in the qp header file.

With this commit, the drivers using rdmavt need not define query_device
function. But they should fill in the IB device attributes structure

Encountered the below just after booting my NFS/RDMA
server with 4.4.0-rc6-00011-g6948cb2 (k.o/for-4.5 plus
my NFS/RDMA for-4.5 patches). The system is up and
ping-able via eth0, but high-level networking (like sshd
and nfsd) does not work, and my ib0 i/f is missing.
This is an x86_64 system with
Until all queue pair functionality is moved to rdmavt we need to provide
access to the reset function. This is only temporary and will be reverted
back to a static, non exported function in the end.

Adding IB user context alloc and dealloc functions to rdmavt so that the
drivers that use rdmavt can use these functions instead of defining their
own functions.

This patch set removes the ibport from qib and starts to add in more support for
rdamvt provided verbs functionality. Included is AH notification, pkey support,
and queue pair creation.
This patchset builds on the "Start to add qp support to rdmavt and other verbs"
patchset.

Since mmap functionality has been moved into rdmavt, its time for qib to
use that.

Remove qib query pkey function which is no longer needed as this is now
being done in rdmavt. The allocation and maintenance of the list still
resides in the driver.

Rely on rdmavt functions for creation of qp and qp table. Function to
allocate a qpn is still being provided by qib as the algorithm to allocate
a qpn in qib is different from that of the algorithm in rdmavt.
