React to the TC messages that were introduced in a preceding patch and
configure egress maximum shaper as appropriate. TBF can be used as a root
qdisc or under one of PRIO or strict ETS bands.

In order to allow configuration of burst size together with shaper rate,
extend mlxsw_sp_port_ets_maxrate_set() with a burst_size argument. Convert
call sites to pass 0 (for default).

As the port speeds grow, the current value of "unlimited shaper",
200000000Kbps, might become lower than the actually supported speeds. Bump
it to the maximum value that fits in the corresponding QEEC field, which is
about 2.1Tbps.

When the RED Qdisc is unoffloaded, it needs to reduce the reported backlog
by the amount that is in the HW, so that only the SW backlog is contained
in the counter. The same thing will need to be done by TBF, and likely any
other leaf Qdisc as well.
Extract a helper mlxsw_sp_qdisc_leaf_unoffload() and call it from
mlxsw_sp_qdisc_red_unoffload().

This patch adds support of XDP in native mode for hv_netvsc driver, and
transparently sets the XDP program on the associated VF NIC as well.
Setting / unsetting XDP program on synthetic NIC (netvsc) propagates to
VF NIC automatically. Setting / unsetting XDP program on VF NIC directly
is not recommended, also not propagated to synthetic NIC, and may be
overwritten by setting of synthetic NIC.
The Azure/Hyper-V synthetic NIC receive buffer doesn't provide headroom
for XDP. We thought about re-use the RNDIS header space, but it's too
small. So we decided to copy the packets to a page buffer for XDP. And,
most of our VMs on Azure have Accelerated Network (SRIOV) enabled, so
most of the packets run on VF NIC. The synthetic NIC is considered as a
fallback data-path. So the data copy on netvsc won't impact performance
significantly.
XDP program cannot run with LRO (RSC) enabled, so you need to disable LRO
before running XDP:
ethtool -K eth0 lro off
XDP actions not yet supported:

====================
mlx5-updates-2020-01-22
This series provides updates to mlx5 driver.
1) Misc small cleanups
2) Some SW steering updates including header copy support
3) Full ethtool statistics support for E-Switch uplink representor
Some refactoring was required to share the bare-metal NIC ethtool
stats with the Uplink representor. On Top of this Vlad converts the
ethtool stats support in E-Swtich vports representors to use the mlx5e
"stats groups" infrastructure and then applied all applicable stats
to the uplink representor netdev.

In order to support all of the supported stats that are available in legacy
mode for switchdev uplink representors, convert rep stats infrastructure to
reuse struct mlx5e_stats_grp that is already used when device is in legacy
mode. Refactor rep code to use array of mlx5e_stats_grp
structures (constructed using macros provided by stats infra) to
fill/update stats, instead of fixed hardcoded set of values. This approach
allows to easily extend representors with new stats types.

In the flowtables offload all the devices in the flowtables
share the same flow_block. An offload rule will be installed on
all the devices. This scenario is not correct.
It is no problem if there are only two devices in the flowtable,
The rule with ingress and egress on the same device can be reject
by driver.
But more than two devices in the flowtable will install the wrong
rules on hardware.
For example:
Three devices in a offload flowtables: dev_a, dev_b, dev_c
A rule ingress from dev_a and egress to dev_b:
The rule will install on device dev_a.
The rule will try to install on dev_b but failed for ingress
and egress on the same device.
The rule will install on dev_c. This is not correct.
The flowtables offload avoid this case through restricting the ingress dev
with FLOW_DISSECTOR_KEY_META.
So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse.

since mlx5 hardware can segment correctly TSO packets on VXLAN over VLAN
topologies, CPU usage can improve significantly if we enable tunnel
offloads in dev->vlan_features, like it was done in the past with other
NIC drivers (e.g. mlx4, be2net and ixgbe).

Since the bulk queue used by XDP_REDIRECT now lives in struct net_device,
we can re-use the bulking for the non-map version of the bpf_redirect()
helper. This is a simple matter of having xdp_do_redirect_slow() queue the
frame on the bulk queue instead of sending it out with __bpf_tx_xdp().
Unfortunately we can't make the bpf_redirect() helper return an error if
the ifindex doesn't exit (as bpf_redirect_map() does), because we don't
have a reference to the network namespace of the ingress device at the time
the helper is called. So we have to leave it as-is and keep the device
lookup in xdp_do_redirect_slow().
Since this leaves less reason to have the non-map redirect code in a
separate function, so we get rid of the xdp_do_redirect_slow() function
entirely. This does lose us the tracepoint disambiguation, but fortunately
the xdp_redirect and xdp_redirect_map tracepoints use the same tracepoint
entry structures. This means both can contain a map index, so we can just
amend the tracepoint definitions so we always emit the xdp_redirect(_err)
tracepoints, but with the map ID only populated if a map is present. This
means we retire the xdp_redirect_map(_err) tracepoints entirely, but keep
the definitions around in case someone is still listening for them.
With this change, the performance of the xdp_redirect sample program goes
from 5Mpps to 8.4Mpps (a 68% increase).
Since the flush functions are no longer map-specific, rename the flush()
functions to drop _map from their names. One of the renamed functions is
the xdp_do_flush_map() callback used in all the xdp-enabled drivers. To
keep from having to update all drivers, use a #define to keep the old name
working, and only update the virtual drivers in this patch.

HNS3 driver allocates pages for DMA with dev_alloc_pages(), which
calls alloc_pages_node() with the __GFP_MEMALLOC flag. So, in case
of OOM condition, HNS3 can get pages with pfmemalloc flag set.
So do not reuse the pages with pfmemalloc flag set because those
pages are reserved for special cases, such as low memory case.

snprintf returns the number of bytes that would be written, which may be

scnprintf to simplify the code.
