Pull base rdma updates from Doug Ledford:
"Round one of 4.8 code: while this is mostly normal, there is a new
driver in here (the driver was hosted outside the kernel for several
years and is actually a fairly mature and well coded driver). It
amounts to 13,000 of the 16,000 lines of added code in here.
Summary:
- Updates/fixes for iw_cxgb4 driver
- Updates/fixes for mlx5 driver
- Add flow steering and RSS API
- Add hardware stats to mlx4 and mlx5 drivers
- Add firmware version API for RDMA driver use
- Add the rxe driver (this is a software RoCE driver that makes any
Ethernet device a RoCE device)
- Fixes for i40iw driver
- Support for send only multicast joins in the cma layer
- Other minor fixes"

The commit 637d3e997351 ("cxgb4: Discard the packet if the length is
greater than mtu") introduced a regression in the VLAN interface
performance when Tx VLAN offload is disabled.
Check if skb is tagged, regardless of whether it is hardware accelerated
or not. Presently we were checking only for hardware acclereated one,
which caused performance to drop to ~0.17Mbps on a 10GbE adapter for
VLAN interface, when tx vlan offload is turned off using ethtool.
The ethernet head length calculation was going wrong in this case, and
driver ended up dropping packets.

Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.
Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.
In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.

The FID value in a ULP_MEMIO command needs to be set to an IQ ID of
a queue configured for our PF. The FID/IQ id is used to index into the
PCIE FID table, to find out on which function the DMA needs to be
issued. Essentially, every DMA needs to have the ingress queue. The exact
ingress queue doesn't matter, but it needs to be an ingress queue
associated with the function you want to see the DMA on.

When cxgb4 is enabled with CONFIG_CHELSIO_T4_DCB set, VI enable command
gets called with DCB enabled. But when we have a back to back setup with
DCB enabled on one side and non-DCB on the Peer side. Firmware doesn't
send any DCB_L2_CFG, and DCB priority is never set for Tx queue.
But driver resets the queue priority and state machine whenever there
is a link down, this patch fixes it by adding a check to reset only if
cxgb4_dcb_enabled() returns true.

The firmware can send a set of asynchronous replies through FW_PORT_CMD
with DCBX information when that's negotiated with the Link Peer. The old
code always assumed that a FW_PORT_CMD reply was always a Get Port
Information message. This change conditionalizes the code to only handle
the Get Port Information messages and throws a warning if we don't
understand what we've been given.
Also refactor t4_handle_fw_rpl() so that core functionality performed by
t4_handle_get_port_info() for a specified port.

Pull PCI fixes from Bjorn Helgaas:
"These are fixes for two issues:
- The VPD parsing code we added for v4.6 keeps some devices from
crashing, but also keeps cxgb4 from reading non-standard extra VPD
data that is relies on. Hariprasad added a way for the driver to
specify how much VPD is valid.
- The i.MX6 active-low reset GPIO support we added in v4.5 caused
regressions on some boards, so we're reverting that.

Add pci_set_vpd_size() (Hariprasad Shenai)

Chelsio adapters have two VPD structures stored in the VPD:
- offset 0x000: an abbreviated VPD, and
- offset 0x400: the complete VPD.
After 104daa71b396 ("PCI: Determine actual VPD size on first access"), the
PCI core computes the valid VPD size by parsing the VPD starting at offset
0x0. That size only includes the abbreviated VPD structure, so reads of
the complete VPD at 0x400 fail.
Explicitly set the VPD size with pci_set_vpd_size() so the driver can read
both VPD structures.

return int (not ssize_t)]

Stop all Ethernet RX Queues before freeing up various Ingress/Egress
Queues, etc. We were seeing cases of Ingress Queues not getting serviced
during the shutdown process leading to Ingress Paths jamming up through
the chip and blocking the shutdown effort itself.
One such case involved the Firmware sending a "Flush Token" through the
ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to
make sure there weren't any remaining TX Work Requests in the pipeline.
But the return path was stalled by Ingress Data unable to be delivered to
the Host because those Ingress Queues were no longer being serviced.

Minimum value. So if we set FBMIN to 64 bytes and the Host Driver
