IB/core: Add support for XDR link speed

[ Upstream commit 703289ce43f740b0096724300107df82d008552f ]

Add new IBTA speed XDR, the new rate that was added to Infiniband spec
as part of XDR and supporting signaling rate of 200Gb.

In order to report that value to rdma-core, add new u32 field to
query_port response.

=====================================================

If __ethtool_get_link_ksettings() fails, `netdev_speed` is set to the
default value, SPEED_1000. In this case, if `lanes` field of struct
ethtool_link_ksettings is not initialized, an uninitialized value is passed
to ib_get_width_and_speed(). This causes the above issue. This patch
resolves the issue by initializing `lanes` to 0.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
"Many small changes across the subystem, some highlights:

- Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma,
mthca, hns, and bnxt_re

- siw now works over tunnel and other netdevs with a MAC address by
removing assumptions about a MAC/GID from the connection manager

- "Doorbell Pacing" for bnxt_re - this is a best effort scheme to
allow userspace to slow down the doorbell rings if the HW gets full

- irdma egress VLAN priority, better QP/WQ sizing

- rxe bug fixes in queue draining and srq resizing

- Support more ethernet speed options in the core layer

- DMABUF support for bnxt_re

- Multi-stage MTT support for erdma to allow much bigger MR
registrations

- A irdma fix with a CVE that came in too late to go to -rc, missing
bounds checking for 0 length MRs"

RDMA/core: Get IB width and speed from netdev

Previously, there was no way to query the number of lanes for a network

speed.

RDMA/core: Get IB width and speed from netdev

Previously, there was no way to query the number of lanes for a network
card, so the same netdev_speed would result in a fixed pair of width and
speed. As network card specifications become more diverse, such fixed
mode is no longer suitable, so a method is needed to obtain the correct
width and speed based on the number of lanes.

This patch retrieves netdev lanes and speed from net_device and
translates them to IB width and speed.
