ENETC has ethernet MACs capable of SGMII, 2500BaseX and USXGMII. But in
order to use these protocols some SerDes configurations need to be
performed. The SerDes is configurable via an internal PCS PHY which is
connected to an internal MDIO bus at address 0.
This patch basically removes the depende
These patches were picked from the following series:
https://lore.kernel.org/netdev/1567779344-30965-1-git-send-email-claudiu.man...@nxp.com/
They have never been resent. I've picked them up, addressed Andrews
comments, fixed some more bugs and asked Claudiu if I can keep their SOB
tags; he agreed.
The ENETC has the same PCS PHY and thus needs the same definitions. Move
them into the common enetc_mdio.h header which has already the macros
for the SGMII PCS.

Use DT information rather than in-band information from bootloader to
set up MAC for XGMII. For RGMII use the DT indication in addition to
RGMII defaults in hardware.
However, this implies that PHY connection information needs to be
extracted before netdevice creation, when t

Hi Dave,

instead switches their users to small functions that implement setting a
sockopt directly using a normal kernel function call with type safety and

Introduce infrastructure to create unique metadata for match
for vport without depending on vport_num. Vport uses its
default metadata for match in standalone configuration but
will share a different unique "bond_metadata" for match with
other vports in bond configuration.

By default, e-switch vport's egress acl just forward packets to its
counterpart NIC vport using existing egress acl table.
During port failover in bonding scenario where two VFs representors
are bonded, the egress acl forward-to-vport rule will be added to
the existing egress acl t

Hi Dave/Jakub.
This series adds support for mlx5 switchdev VM failover using FW bonded
representor vport and probed VF interface via eswitch vport ACLs.
Plus some extra misc updates.

When a bond device is created over one or more non uplink representors,
and when a flow rule is offloaded to such bond device, offload a rule
to the active lower device.
Assuming that this is active-backup lag, the rules should be offloaded
to the active lower device which is th

SJA1105, being AVB/TSN switches, provide hardware assist for the
Credit-Based Shaper as described in the IEEE 8021Q-2018 document.
First generation has 10 shapers, freely assignable to any of the 4
external ports and 8 traffic classes, and second generation has 16
shapers.

Add BPF_XDP_DEVMAP attach type for use with programs associated with a
DEVMAP entry.
Allow DEVMAPs to associate a program with a device entry by adding
a bpf_prog_fd to 'struct devmap_val'. Values read show the program
id, so the fd and id are a union.
The program associated w
Support SEC("xdp_dm*") as a short cut for loading the program with
type BPF_PROG_TYPE_XDP and expected attach type BPF_XDP_DEVMAP.

Add 'struct devmap_val' to the bpf uapi to formalize the
expected values that can be passed in for a DEVMAP.
Update devmap code to use the struct.

Add tests to verify ability to add an XDP program to a
entry in a DEVMAP.
Add negative tests to show DEVMAP programs can not be
attached to devices as a normal XDP program, and accesses
to egress_ifindex require BPF_XDP_DEVMAP attach type.
