This patch provides support for the presence of a KR redriver chip in
between the device PCS and an external PHY. When a redriver chip is
present the device must perform clause 73 auto-negotiation in order to
set the redriver chip for the downstream connection.

The current per channel DMA interrupt support is based on an edge

the disable_irq/enable_irq functions in order to prevent interrupts
during napi processing. The hardware now has a way to configure the per

prevents calling disable_irq/enable_irq now. This patch makes use of

Update the reading of the Tx timestamp to account for a hardware issue
on how the fields and interrupt are cleared. The "seconds" portion of
the timestamp should be read first, followed by the "nanoseconds" portion.
Reading the "nanoseconds" portion should clear the timestamp data and the
interrupt. Because of an issue with the hardware this order is reversed
and reading the "seconds" portion actually clears the timestamp. The code
currently follows this workaround, but to guard against future versions
where this is fixed add a field to the version data to indicate if the
workaround is required or not.

openvswitch: support for layer 3 encapsulated packets
At the core of this patch set is removing the assumption in Open vSwitch
datapath that all packets have Ethernet header.
The implementation relies on the presence of pop_eth and push_eth actions
in datapath flows to facilitate adding and removing Ethernet headers as
appropriate. The construction of such flows is left up to user-space.
This series is based on work by Simon Horman, Lorand Jakab, Thomas Morin and
others. I kept Lorand's and Simon's s-o-b in the patches that are derived
from v11 to record their authorship of parts of the code.
Changes from v12 to v13:
* Addressed Pravin's feedback.
* Removed the GRE vport conversion patch; L3 GRE ports should be created by
rtnetlink instead.
Main changes from v11 to v12:
* The patches were restructured and split differently for easier review.
* They were rebased and adjusted to the current net-next. Especially MPLS
handling is different (and easier) thanks to the recent MPLS GSO rework.
* Several bugs were discovered and fixed. The most notable is fragment
handling: header adjustment for ARPHRD_NONE devices on tx needs to be done
after refragmentation, not before it. This required significant changes in
the patchset. Another one is stricter checking of attributes (match on L2
vs. L3 packet) at the kernel level.
* Instead of is_layer3 bool, a mac_proto field is used.

We'll need it to alter packets sent to ARPHRD_NONE interfaces.
Change do_output() to use the actual L2 header size of the packet when
deciding on the minimum cutlen. The assumption here is that what matters is
not the output interface hard_header_len but rather the L2 header of the
particular packet. For example, ARPHRD_NONE tunnels that encapsulate
Ethernet should get at least the Ethernet header.

Use a hole in the structure. We support only Ethernet so far and will add
a support for L2-less packets shortly. We could use a bool to indicate
whether the Ethernet header is present or not but the approach with the
mac_proto field is more generic and occupies the same number of bytes in the
struct, while allowing later extensibility. It also makes the code in the
next patches more self explaining.
It would be nice to use ARPHRD_ constants but those are u16 which would be
waste. Thus define our own constants.
Another upside of this is that we can overload this new field to also denote
whether the flow key is valid. This has the advantage that on
refragmentation, we don't have to reparse the packet but can rely on the
stored eth.type. This is especially important for the next patches in this
series - instead of adding another branch for L2-less packets before calling
ovs_fragment, we can just remove all those branches completely.

This patch set fixes a bug in bpf_redirect(dev, flags) when dev is an

IP-IP.
Patch 1 adds a dev->type test similar to dev_is_mac_header_xmit()

The test creates two netns, ns1 and ns2. The host (the default netns)
has an ipip or ip6tnl dev configured for tunneling traffic to the ns2.
ping VIPS from ns1 <----> host <--tunnel--> ns2 (VIPs at loopback)
The test is to have ns1 pinging VIPs configured at the loopback
interface in ns2.
The VIPs are 10.10.1.102 and 2401:face::66 (which are configured
at lo@ns2). [Note: 0x66 => 102].
At ns1, the VIPs are routed _via_ the host.
At the host, bpf programs are installed at the veth to redirect packets
from a veth to the ipip/ip6tnl. The test is configured in a way so
that both ingress and egress can be tested.
At ns2, the ipip/ip6tnl dev is configured with the local and remote address
specified. The return path is routed to the dev ipip/ip6tnl.
During egress test, the host also locally tests pinging the VIPs to ensure
that bpf_redirect at egress also works for the direct egress (i.e. not
forwarding from dev ve1 to ve2).

If the bpf program calls bpf_redirect(dev, 0) and dev is
an ipip/ip6tnl, it currently includes the mac header.
e.g. If dev is ipip, the end result is IP-EthHdr-IP instead
of IP-IP.
The fix is to pull the mac header. At ingress, skb_postpull_rcsum()
is not needed because the ethhdr should have been pulled once already
and then got pushed back just before calling the bpf_prog.
At egress, this patch calls skb_postpull_rcsum().
If bpf_redirect(dev, BPF_F_INGRESS) is called,
it also fails now because it calls dev_forward_skb() which
eventually calls eth_type_trans(skb, dev). The eth_type_trans()
will set skb->type = PACKET_OTHERHOST because the mac address
does not match the redirecting dev->dev_addr. The PACKET_OTHERHOST
will eventually cause the ip_rcv() errors out. To fix this,
____dev_forward_skb() is added.

in the error path when mlx4_en_try_alloc_resources() is failing from
mlx4_xdp_set().
We previously took bpf_prog_add(prog, priv->rx_ring_num - 1), that we
need to release again. Earlier in the call path, dev_change_xdp_fd()
itself holds a reference to the prog as well (hence the '- 1' in the
bpf_prog_add()), so a simple atomic_sub() is safe to use here. When
an error is propagated, then bpf_prog_put() is called eventually from
dev_change_xdp_fd()

the exact irq type. Additionally it changes a little oddity in the
