Hi Willy/Florian/Lukas,
disabling nf_conntrack_tcp_loose (solved the problem) and for last 24 hours,
we are not evening seeing a single wrong connection data by send-proxy.
Worth a note in your documentation related to this, as users might be aware off.
Thanks very much for your help and suppo

This patchset adds support for VXLAN tunneling on the Spectrum-2 ASIC.
Spectrum-1 and Spectrum-2 are largely backward compatible in this area,
so not too many changes are required.
Patches #1-#2 expose a function and perform small refactoring towards
the actual Spectrum-2 implementation in patches
Enable VXLAN on Spectrum-2 as previous patches added the required
functionality.
Note that for now Spectrum-1 and Spectrum-2 use the same function to
determine whether the VXLAN configuration is valid or not. In the
future, when the driver will be extended to support features not present

This patch adds support for initializing the MACsec engine found within
the Microsemi Ocelot PHY. The engine is initialized in a passthrough
mode and does not modify any incoming or outgoing packet. But thanks to
this it now can be configured to perform MACsec transformations on
packets, which will
This patch introduces the MACsec hardware offloading infrastructure.
The main idea here is to re-use the logic and data structures of the
software MACsec implementation. This allows not to duplicate definitions
and structure storing the same kind of information. It also allows to
use a unified gen
This patch adds MACsec support to the Microsemi Ocelot PHY, to configure
flows and transformations so that matched packets can be processed by
the MACsec engine, either at egress, or at ingress. This addition allows
a user to create an hardware accelerated virtual MACsec interface on a
port using a
This patch introduces a phy_driver MACsec helper to allow PHYs to
implement a MACsec offloading solution. The phy_driver MACsec helper is
called through a wrapper, phy_macsec, to perform this call while holding
the phydev lock.

This patch exports the __phy_read_page and __phy_write_page helpers, to
allow reading and setting the current page when a function already holds
the MDIO lock.
This is something the Microsemi PHY driver does during its
initialization because parts of its registers and engines are shared

Hello,
This series intends to add support for offloading MACsec transformations
in hardware enabled devices. The series is divided in two parts: the
first 7 patches add the infrastructure support to offload a MACsec
configuration to hardware drivers; and the last 3 patches introduce the
MACsec off
This patch introduce a new netdev feature, which will be used by drivers
to state they can perform MACsec transformations in hardware.

This patch introduces the netdev_macsec structure. It will be used
in the kernel to exchange information between the common MACsec
implementation (macsec.c) and the MACsec hardware offloading
implementations. This structure contains a command (struct
netdev_macsec_command) and pointers to MACsec sp
This patch moves some structure, type and identifier definitions into a
MACsec specific header. This patch does not modify how the MACsec code
is running and only move things around. This is a preparation for the
future MACsec hardware offloading support, which will re-use those
definitions outside
