Vlan tagged packets are getting dropped when used with DPDK that uses
the AF_PACKET interface on a hyperV guest.
The packet layer uses the tpacket interface to communicate the vlans
information to the upper layers. On Rx path, these drivers can read the

This check of ip head checksum should be add in ipvlan_get_L3_hdr，if the

enetc_imdio_remove() is missing from the enetc_pf_probe()

is registering the imdio bus for internal purposes, and it's
not obvious that enetc_imdio_remove() currently performs the

Hi Helmut
This patch probably is correct. But it is not obviously correct,
because there are so many changes at once.
For ENETC ports that register an external MDIO bus,
the bus doesn't get removed on the error bailout path
of enetc_pf_probe().
This issue became much more visible after recent:
commit 07095c025ac2 ("net: enetc: Use DT protocol information to set up the
ports")
Before this commit, one could make p
DAN-P (Dual Attached Nodes PRP) nodes are expected to receive
traditional IP packets as well as PRP (Parallel Redundancy
Protocol) tagged (trailer) packets. PRP trailer is 6 bytes

Print PRP specific information from node table as part of debugfs

on the info from node table.

Parallel Redundancy Protocol (PRP) is another redundancy protocol
introduced by IEC 63439 standard. It is similar to HSR in many
aspects:-
- Use a pair of Ethernet interfaces to created the PRP device
- Use a 6 byte redundancy protocol part (RCT, Redundancy Check
Trailer) similar to HSR Tag.
As a preparatory patch to introduce PRP protocol support in the
driver, refactor the skb init code to a separate function.

Hello,
This series is dependent on the following patches sent out to
netdev list. All (1-3) are already merged to net/master as of
sending this, but not on the net-next master branch. So need
to apply them to net-next before applying this series. v3 of
the iproute2 patches can be merged to work wi
Add support for generation of PRP supervision frames. For PRP,
supervision frame format is similar to HSR version 0, but have
a PRP Redundancy Control Trailer (RCT) added and uses a different
message type, PRP_TLV_LIFE_CHECK_DD. Also update

As a preparatory patch to introduce PRP, refactor the code specific to
handling HSR frames into separate functions and call them through
proto_ops function pointers.

This commit adds task isolation hooks as follows:
- __handle_domain_irq() and handle_domain_nmi() generate an
isolation warning for the local task
- irq_work_queue_on() generates an isolation warning for the remote
task being interrupted for irq_work (through
__smp_call_single_queue())
