mlx5 flow hash field retrieval and set only worked on the default
RSS context as of commit f01cc58c18d6 ("net/mlx5e: Support multiple RSS
contexts"), not custom RSS contexts.
For example, before this patch attempting to retrieve the flow hash fields
for RSS context 1 fails:
$ sudo ethtool -u eth1 rx-flow-hash tcp4 context 1
Cannot get RX network flow hashing options: Invalid argument
This patch fixes getting and setting the flow hash fields for contexts
other than the default context.
Getting the flow hash fields for RSS context 1:
$ sudo ethtool -u eth1 rx-flow-hash tcp4 context 1
For RSS context 1:
TCP over IPV4 flows use these fields for computing Hash flow key:
IP DA
Now, setting the flash hash fields to a custom value:
$ sudo ethtool -U eth1 rx-flow-hash tcp4 sdfn context 1
And retrieving them again:
$ sudo ethtool -u eth1 rx-flow-hash tcp4 context 1
For RSS context 1:
TCP over IPV4 flows use these fields for computing Hash flow key:
IP SA
IP DA
L4 bytes 0 & 1 [TCP/UDP src port]
L4 bytes 2 & 3 [TCP/UDP dst port]

The driver used to pass received CAN frames/skbs to the network stack
with netif_rx(). In netif_rx() the skbs are queued to the local CPU.
If IRQs are handled in round robin, OoO packets may occur.
To avoid out-of-order reception convert the driver from netif_rx() to
NAPI.
For USB devices with timestamping support use the rx-offload helper
can_rx_offload_queue_timestamp() for the RX, and
can_rx_offload_get_echo_skb_queue_timestamp() for the TX path. Devices
without timestamping support use can_rx_offload_queue_tail() for RX,
and can_rx_offload_get_echo_skb_queue_tail() for the TX path.

can_rx_offload_get_echo_skb_queue_timestamp()
Rename the rx_offload_get_echo_skb() function to
can_rx_offload_get_echo_skb_queue_timestamp(), since it inserts the
echo skb into the rx-offload queue sorted by timestamp.
This is a preparation for adding
can_rx_offload_get_echo_skb_queue_tail(), which adds the echo skb to
the end of the queue. This is intended for devices that do not support
timestamps.

When the USB device is unplugged, gs_can_close() (which implements the

an attempt is made to shut down the USB device with a USB control

As part of that merge prepping Arm DT support 13 years ago, they
