The IP addresses of tunnel endpoint at H3 are set at the VLAN device
$h3.555. Therefore when test_gretap_untagged_egress() sets vlan 555 to
egress untagged at $swp3, $h3's rp_filter rejects these packets. The
test then spuriously fails.
Therefore turn off net.ipv4.conf.{all, $h3}.rp_filter.

For the TC clsact offload these days, some of HW drivers need
to hold a magic ball. The reason is, with the first inserted rule inside
HW they need to guess what fields will be used for the matching. If
later on this guess proves to be wrong and user adds a filter with a

The shared block support is only needed for tc_shblock.sh. No need to
require that for other test.

TC shared blocks allow multiple qdiscs to be grouped together and filters
shared between them. Currently the chains of filters attached to a block
are only flushed when the block is removed. If a qdisc is removed from a
block but the block still exists, flow del messages are not
Hi!
This series brings two fixes to TC filter/action offload code.
Pieter fixes matching MPLS packets when the match is purely on
the MPLS ethertype and none of the MPLS fields are used.
John provides a fix for offload of shared blocks. Unfortunately,
with shared blocks there is currently no guar
From: Pieter Jansen van Vuuren
Previously it was not possible to distinguish between mpls ether types and
other ether types. This leads to incorrect classification of offloaded
filters that match on mpls ether type. For example the following two
filters overlap:

Fair.
Most of the installations where I needed D.G.D. to work would be okay

So far unsupported WoL options are silently ignored. Change this and
reject attempts to set unsupported options. This prevents situations
where a user tries to set an unsupported WoL option and is under the
impression it was successful because ethtool doesn't complain.
