RoCE device changes cause an IB event, processed in the global event
handler for the ROCE device. Problems for a certain Queue Pair cause a QP

Among those events are port errors and other fatal device errors. All

net/ipv6: Add support for ONLINK flag
Add support for RTNH_F_ONLINK with ipv6 routes.
First patch moves existing gateway validation into helper. The onlink
flag requires a different set of checks and the existing validation
makes ip6_route_info_create long enough.
Second patch makes the table id and lookup flag an option to
ip6_nh_lookup_table. onlink check needs to verify the gateway without
the RT6_LOOKUP_F_IFACE flag and PBR with VRF means the table id can
vary between the table the route is inserted and the VRF the egress
device is enslaved to.
Third patch adds support for RTNH_F_ONLINK.
I have a set of test cases in a format based on the framework Ido and
Jiri are working on. Once that goes in I will adapt the script and
submit.
v2
- removed table id check. Too constraining for PBR with VRF use cases

Similar to IPv4 allow routes to be added with the RTNH_F_ONLINK flag.
The onlink option requires a gateway and a nexthop device. Any unicast
gateway is allowed (including IPv4 mapped addresses and unresolved
ones) as long as the gateway is not a local address and if it resolves
it must match the given device.

onlink verification needs to do a lookup in potentially different
table than the table in fib6_config and without the RT6_LOOKUP_F_IFACE
flag. Change ip6_nh_lookup_table to take table id and flags as input
arguments. Both verifications want to ignore link state, so add that
flag can stay in the lookup helper.

Message sends to the local broadcast address (255.255.255.255) require
uc_index or sk_bound_dev_if to be set to an egress device. However,
responses or only received if the socket is bound to the device. This
is overly constraining for processes running in an L3 domain. This
patch allows a socket bound to the VRF device to send to the local
broadcast address by using IP_UNICAST_IF to set the egress interface
with packet receipt handled by the VRF binding.
Similar to IP_MULTICAST_IF, relax the constraint on setting
IP_UNICAST_IF if a socket is bound to an L3 master device. In this
case allow uc_index to be set to an enslaved if sk_bound_dev_if is
an L3 master device and is the master device for the ifindex.
In udp and raw sendmsg, allow uc_index to override the oif if
uc_index master device is oif (ie., the oif is an L3 master and the
index is an L3 slave).

net: erspan: add support for openvswitch
The first patch refactors the erspan header definitions.
Originally, the erspan fields are defined as a group into a __be16 field,
and use mask and offset to access each field. This is more costly due to
calling ntohs/htons and error-prone. The first patch changes it to use
bitfields. The second patch creates erspan.h in UAPI and move the definition
'struct erspan_metadata' to it for later openvswitch to use. The final patch
introduces the new OVS tunnel key attribute, OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS,
to program both v1 and v2 erspan tunnel for openvswitch.

====================
use tc_cls_can_offload_and_chain0() throughout the drivers
This set makes all drivers use a new tc_cls_can_offload_and_chain0()
helper which will set extack in case TC hw offload flag is disabled.
I chose to keep the new helper which also looks at the chain but
renamed it more appropriately. The rationale being that most drivers
don't accept chains other than 0 and since we have to pass extack
to the helper we can as well pass the entire struct tc_cls_common_offload
and perform the most common checks.
This code makes the assumption that type_data in the callback can
be interpreted as struct tc_cls_common_offload, i.e. the real offload
structure has common part as the first member. This allows us to
make the check once for all classifier types if driver supports
more than one.
v1:
- drop the type validation in nfp and netdevsim.
v2:
- reorder checks in patch 1;
- split other changes from patch 1;
- add the i40e patch in;
- add one more test case - for chain 0 extack.
