This patch enables UDP GSO support. We enable this by using two WQEs
the first is a UDP LSO WQE for all segments with equal length, and the
second is for the last segment in case it has different length.
Due to HW limitation, before sending, we must adjust the packet length fields.

net: sched: support replay of filter offload when binding to block
This series from John adds the ability to replay filter offload requests
when new offload callback is being registered on a TC block. This is most
likely to take place for shared blocks today, when a block which already
has rules is bound to another interface. Prior to this patch set if any
of the rules were offloaded the block bind would fail.
A new tcf_proto_op is added to generate a filter-specific offload request.
The new 'offload' op is supporting extack from day 0, hence we need to
propagate extack to .ndo_setup_tc TC_BLOCK_BIND/TC_BLOCK_UNBIND and
through tcf_block_cb_register() to tcf_block_playback_offloads().
The immediate use of this patch set is to simplify life of drivers which
require duplicating rules when sharing blocks. Switch drivers (mlxsw)
can bind ports to rule lists dynamically, NIC drivers generally don't
have that ability and need the rules to be duplicated for each ingress
they match on. In code terms this means that switch drivers don't
register multiple callbacks for each port. NIC drivers do, and get a
separate request and hance rule per-port, as if the block was not shared.
The registration fails today, however, if some rules were already present.
As John notes in description of patch 7, drivers which register multiple
callbacks to shared blocks will likely need to flush the rules on block
unbind. This set makes the core not only replay the the offload add
requests but also offload remove requests when callback is unregistered.
v2:
- name parameters in patch 2;
- use unsigned int instead of u32 for in_hw_coun;
- improve extack message in patch 7.

block when a callback tries to register to a block that already has
offloaded rules. If all existing rules cannot be offloaded then the
registration is rejected. This replaces the previous policy of rejecting
such callback registration outright.
On unregistration of a callback, the rules are flushed for that given cb.
The implementation of block sharing in the NFP driver, for example,
duplicates shared rules to all devs bound to a block. This meant that
rules could still exist in hw even after a device is unbound from a block

mlxsw: Support bridge router interfaces with non-default VLAN
Petr says:
When traffic is inserted on a router interface associated with an 802.1q
bridge, the VLAN that the traffic appears on is determined by PVID of
the bridge device itself. However currently mlxsw always configures such
traffic to be forwarded to VLAN 1, regardless of the bridge PVID.
Fix the problem by modifying the FID-handling code to assign such
traffic not to FID that corresponds to VLAN 1, but to a FID that
corresponds to the configured PVID. Bail out if there is no PVID. This
is implemented in patches #1 and #2.
From that point on, also forbid any changes to bridge device PVID,
because such changes would not be reflected. This is implemented in
patches #3, #4 and #5.
Finally in patch #6, introduce tests that use bridge as a routed
interface, and test mlxsw in both the currently-supported scenario of
using PVID 1, and the newly-supported one of using a custom PVID.

selftests: forwarding: Test routed bridge interface
Add test for cases where bridge itself acts as a router interface, with
front panel port attached to the bridge in question.
In the first test (router_bridge.sh), VLAN memberships are not
configured in any way, and everything uses default PVID of 1. Thus
traffic in $h1 and $h2 is untagged. This test ensures that the previous
patches didn't break a currently working scenario.
In the second test (router_bridge_vlan.sh), a VLAN 555 pvid untagged is
added to the bridge CPU port, with that VLAN leaving the bridge tagged
through its sole member port. The traffic is therefore expected to come
out tagged at $h1. This tests the fix introduced in the previous
patches.

Convert GRO receive over to hash table.
When many parallel flows are present and being received on the same
RX queue, GRO processing can become expensive because each incoming
frame must traverse the per-NAPI GRO list at each protocol layer
of GRO receive (eth --> ipv{4,6} --> tcp).
Use the already computed hash to chain these SKBs in a hash table
