pxa168_eth_remove() firstly calls unregister_netdev(),
then cancels a timeout work. unregister_netdev() shuts down a device
interface and removes it from the kernel tables. If the timeout occurs
in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop
and open of the device. It may

Hi,
All three Intel arm64 SoCFPGA architectures (Agilex, N5X and Stratix 10)
are basically flavors/platforms of the same architecture. At least from
the Linux point of view. Up to a point that N5X and Agilex share DTSI.
Having three top-level architectures for the same one barely makes

I see. When i do `ping -I vrf2` to address that was leaked from vrf1
it selects source address that's set as local in vrf1 routing table.
Is this expected behavior? I guess, forwarding packets from vrf1 to
vrf2 local address won't help here.

Hi,
As a lab upgrade I have recently replaced a dated 32-bit x86 server with
a new POWER9 system. One of the purposes of the system has been providing
network based resources to clients over my FDDI network. As such the new
server has also received a new DEFPA FDDI network adapter.

Replace repeated "defxx" strings with a reference to the DRV_NAME macro
and then use the driver's name rather that the bus address with resource
requests so as to have contents of /proc/iomem and /proc/ioports more
meaningful to the user, in line with what drivers usually do.
So rather than say
Since there is a dedicated file in this driver for interacting with
control BD rings, it makes sense to move these functions there.

This series performs the following:
- makes the API for Control Buffer Descriptor Rings in enetc_cbdr.c a
bit more tightly knit.
- moves more logic into enetc_rxbd_next to make the callers simpler
- moves more logic into enetc_refill_rx_ring to make the callers simpler
- removes forward declarati
enetc_alloc_cbdr and enetc_setup_cbdr are always called one after
another, so we can simplify the callers and make enetc_setup_cbdr do
everything that's needed.

We shouldn't need to pass the struct device *dev to enetc CBDR APIs over
and over again, so save this inside struct enetc_cbdr::dma_dev and avoid
calling it from the enetc_free_cbdr functions.
This breaks the dependency of the cbdr API from struct enetc_si (the
station interface).
Signed-off-by:
enetc_clear_cbdr depends on struct enetc_hw because it must disable the
ring through a register write. We'd like to remove that dependency, so
let's do what's already done with the producer and consumer indices,
which is to save the iomem address in a variable kept in struct enetc_cbdr.

All call sites call enetc_clear_cbdr and enetc_free_cbdr one after
another, so let's combine the two functions into a single method named
enetc_teardown_cbdr which does both, and in the same order.

It makes no sense from an API perspective to first initialize some
portion of struct enetc_cbdr outside enetc_setup_cbdr, then leave that
function to initialize the rest. enetc_setup_cbdr should be able to
perform all initialization given a zero-initialized struct enetc_cbdr.

Since commit 3222b5b613db ("net: enetc: initialize RFS/RSS memories for
unused ports too") there is a requirement to initialize the memories of
unused PFs too, which has left the probe path in a bit of a rough shape,
because we basically have a minimal initialization path for unused PFs

When we iterate through the BDs in the RX ring, the software producer
index (which is already passed by value to enetc_rxbd_next) lags behind,
and we end up with this funny looking "++i == rx_ring->bd_count" check
so that we drag it after us.
Let's pass the software producer index "i" by reference
Since commit fd5736bf9f23 ("enetc: Workaround for MDIO register access
issue"), enetc_refill_rx_ring no longer updates the RX BD ring's
consumer index, that is left to be done by the caller. This has led to
bugs such as the ones found in 96a5223b918c ("net: enetc: remove bogus

we can delete the forward declarations.

There is no other reason why this forward declaration exists rather than
poor ordering of the functions.

understanding of these states.

This patch set adds support for Rx/Tx capabilities on DPAA2 switch port

By default, the DPSW object is configured with VLAN ID 1 in the VLAN
table, which all ports are member of. This entry in the VLAN table
selects the same FDB ID for all ports, meaning that forwarding between
ports is permitted. This is unlike the switchdev model, where each por

Since the dpaa2-switch already listens for SWITCHDEV_FDB_ADD_TO_DEVICE /
SWITCHDEV_FDB_DEL_TO_DEVICE events emitted by the bridge, we don't need
the bridge bypass operations, and now is a good time to delete them. All
'bridge fdb' commands need the 'master' flag specified now.
