rds: add tos support
RDS applications make use of tos to classify database traffic.
This feature has been used in shipping products from 2.6.32 based
kernels. Its tied with RDS v4.1 protocol version and the compatibility
gets negotiated as part of connections setup.
Patchset keeps full backward compatibility using existing connection
negotiation scheme. Currently the feature is exploited by RDMA
transport and for TCP transport the user tos values are mapped to
same default class (0).
For RDMA transports, RDMA CM service type API is used to
set up different SL(service lanes) and the IB fabric is configured
for tos mapping using Subnet Manager(SL to VL mappings).
Similarly for ROCE fabric, user priority is mapped with different
DSCP code points which are associated with different switch queues
in the fabric.
The original code was developed by Bang Nguyen in downstream kernel back in
2.6.32 kernel days and it has evolved significantly over period of time.

- Ethernet switch drivers: mlxsw, ocelot, DSA, etc. which implement more

chain

net: Introduce ndo_get_port_parent_id()
In preparation for getting rid of switchdev_ops, create a dedicated NDO
operation for getting the port's parent identifier. There are
essentially two classes of drivers that need to implement getting the
port's parent ID which are VF/PF drivers with a built-in switch, and
pure switchdev drivers such as mlxsw, ocelot, dsa etc.
We introduce a helper function: dev_get_port_parent_id() which supports
recursion into the lower devices to obtain the first port's parent ID.
Convert the bridge, core and ipv4 multicast routing code to check for
such ndo_get_port_parent_id() and call the helper function when valid
before falling back to switchdev_port_attr_get(). This will allow us to
convert all relevant drivers in one go instead of having to implement
both switchdev_port_attr_get() and ndo_get_port_parent_id() operations,
then get rid of switchdev_port_attr_get().

being set incorrectly during a system suspend.
Sasha addresses community feedback on the igc driver and provides a
number of code cleanups to remove either unreachable or unused code. In
addition, added basic ethtool support for the igc driver.
Mike Rapoport fixes the formatting of the kernel driver documentation so
that the title is properly formatted and does not get lumped with the
document sections in the HTML kernel documents generated.
Jiri Kosina updates a hard coded RAR entries value with the existing
define IXGBE_82599_RAR_ENTRIES.
Jake fixes up whitespace in the fm10k driver.
Konstantin Khlebnikov fixes an issue where in some cases, the e1000e
driver will continually reset during a system boot because the watchdog
task sees items in the transmit buffer but the carrier is off (trying to
establish link) causing the device reset to flush the buffer. To
resolve, just move this check/flush into the watchdog section for when
the carrier is off.
Todd bumps the igb driver version to reflect the recent driver changes.

added the API function btf__get_map_kv_tids():
btf__get_map_kv_tids(const struct btf *btf, char *map_name, ...)
The parameter map_name has type "char *". This is okay inside libbpf library since

This will be problematic if the caller for map_name already has attribute "const",
e.g., from C++ string.c_str(). It will result in either a warning or an error.

It broke the raw test:
BTF raw test[71] (func proto (Bad arg name_off)):

The test itself encodes invalid func_proto parameter name

net: marvell: mvpp2: fix lack of link interrupts
Sven Auhagen reports that if he changes a SFP+ module for a SFP module
on the Macchiatobin Single Shot, the link does not come back up. For
Sven, it is as easy as:
- Insert a SFP+ module connected, and use ping6 to verify link is up.
- Remove SFP+ module
- Insert SFP 1000base-X module use ping6 to verify link is up: Link
up event did not trigger and the link is down
but that doesn't show the problem for me. Locally, this has been
reproduced by:
- Boot with no modules.
- Insert SFP+ module, confirm link is up.
- Replace module with 25000base-X module. Confirm link is up.
- Set remote end down, link is reported as dropped at both ends.
- Set remote end up, link is reported up at remote end, but not local
end due to lack of link interrupt.
Fix this by setting up both GMAC and XLG interrupts for port 0, but
only unmasking the appropriate interrupt according to the current mode
set in the mac_config() method. However, only do the mask/unmask
dance when we are really changing the link mode to avoid missing any
link interrupts.
