Håkon Bugge 0ae207fb91 IB/mlx4: Separate tunnel and wire bufs parameters ... Using CX-3 in virtualized mode, MAD packets are proxied through the PF driver. The feed is N tunnel QPs, and what is received from the VFs is multiplexed out on the wire QP. Since this is a many-to-one scenario, it is better to have separate initialization parameters for the two usages. The number of wire and tunnel bufs are yanked up to 2K and 512 respectively. With this set of parameters, a system consisting of eight physical servers, each with eight VMs and 14 I/O servers (BM), can run switch fail-over without seeing: mlx4_ib_demux_mad: failed sending GSI to slave 3 via tunnel qp (-11) or mlx4_ib_multiplex_mad: failed sending GSI to wire on behalf of slave 2 (-11) Fixes: 3cf69cc8db ("IB/mlx4: Add CM paravirtualization") Link: https://lore.kernel.org/r/20200803061941.1139994-4-haakon.bugge@oracle.com Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>		2020-08-24 11:31:21 -03:00
