"set int state <interface> down" puts the virtio device link
down. It will not put the link in "UP" state, when
"set int state <interface up>" will be used again to change
the interface admin up. This patch fixes it.
To test:

Fix a bug that caused some input packets to be dropped due to errors of
the type 'ip4 length > l2 length'. The change is related to the second
call to the rdma_device_input_bufs() function that happens when the end
of the ring buffer is reached.

For chain buffer, need to traverse b->next_buffer to transmit all buffers
in the chain. Only set EOP at the last descriptor in the chain to signal
this is a chain descriptor.
Introduce slow path to handle ring wrap. This is needed because chain
buffer may consist of multiple pieces and it may span from near the end of
the ring to the beginning of the ring.

L4 checksums for IPv6 should be calculated using a pseudo header that
includes the source/destination addresses, payload length, and payload
protocol.
ip6_tcp_udp_icmp_compute_checksum() was using the payload length and
protocol from the IPv6 header. If there is a hop-by-hop header (or any
other extension header), the payload length used for the pseudo header
should only include the upper layer header and payload and not the
extension header bytes. Same deal with the protocol, the upper layer
next header value should be used instead of the extension header.

Recent modification added a call to vnet_gso_header_offset_parser in the
beginning of vhost_user_handle_tx_offload. The former routine may set tcp or
udp->checksum to 0. While it is appropriate to set it to 0 for the GSO packet,
it is broken and causes checksum error if the aformentiooned routine is called
by a non-GSO packet. The fix is to not call vhost_user_handle_tx_offload
if the buffer does not indicate checksum offload is needed.

Updating the document of srv6-mobile plugin code integrated into stable/2001. The reason of this patch just only for the document is that the latest commit to master was reverted by the release master for some reason. The commit included not only the code for new feature, but also the updated document for the already merged code into stable/2001. The previous doc is work-in-progress status in terms of its CLI and features. It seems there is some confusion on this patch is trying to update the document of outside feature of stable/2001 which is not true. This patch exactly reflects the correct information of srv6-mobile plugin within the extent of stable/2001.

Binary API trace replay with multiple worker threads depends in many
cases on worker thread graph replica maintenance. If we (implicitly)
assert a worker thread barrier at the debug CLI level, all graph
replica changes are deferred until the replay operation completes. If

The crash occured trying to retreive a NULL path list to walk the path
extensions. A walk shoul not be required, because there should be no
extensins, since all paths are removed. The problem is that when the
paths were added, they were not sorted, hence neither were the
extensions and when they were updated, duplicate extensions were added,
and hence a path removal did not remove them all.
Fix is to make sure paths are sorted.

This reverts commit 57584d99dd8a8524db90c67c88525d58879d9b8e.
The reasons for reverting:
- the documentation seems "work in progress". Also, 500K of pngs
should probably go on wiki, rather than in the repo. Please
make sure that newly added documentation renders correctly
and sensibly as part of the review/commit process.
- runner.py seems to contain unit tests, so it should
be rewritten in a manner that allows the testing from within
CI (including an unprivileged docker container)
- the above items, especially the testing one, warrant more
work, and at a RC1 milestone time it is probably not
a good idea to include a significant patch without
proper care. I suggest to prepare it so it is ready
for the next release, or cherrypick it for a
20.01.1 release, if having it in stable/2001 is absolute necessity.
- when submitting it, ensure that the commit message
makes sense, especially having "srv6-mobile:" with no further
text should be absolutely avoided.
