====================
rxfh with custom RSS fixes
Greetings:
Welcome to v2, now via net-next. No functional changes; only style
changes (see the summary below).
While attempting to get the RX flow hash key for a custom RSS context on
my mlx5 NIC, I got an error:
$ sudo ethtool -u eth1 rx-flow-hash tcp4 context 1
Cannot get RX network flow hashing options: Invalid argument
I dug into this a bit and noticed two things:
1. ETHTOOL_GRXFH supports custom RSS contexts, but ETHTOOL_SRXFH does
not. I moved the copy logic out of ETHTOOL_GRXFH and into a helper so
that both ETHTOOL_{G,S}RXFH now call it, which fixes ETHTOOL_SRXFH. This
is patch 1/2.
2. mlx5 defaulted to RSS context 0 for both ETHTOOL_{G,S}RXFH paths. I
have modified the driver to support custom contexts for both paths. It
is now possible to get and set the flow hash key for custom RSS contexts
with mlx5. This is patch 2/2.
See commit messages for more details.
Thanks.
v2:
- Rebased on net-next
- Adjusted arguments of mlx5e_rx_res_rss_get_hash_fields and
mlx5e_rx_res_rss_set_hash_fields to move rss_idx next to the rss
argument
- Changed return value of both mlx5e_rx_res_rss_get_hash_fields and
mlx5e_rx_res_rss_set_hash_fields to -ENOENT when the rss entry is
NULL
- Changed order of local variables in mlx5e_get_rss_hash_opt and
mlx5e_set_rss_hash_opt

mlx5 flow hash field retrieval and set only worked on the default
RSS context as of commit f01cc58c18 ("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]

ETHTOOL_GRXFH correctly copies in the full struct ethtool_rxnfc when
FLOW_RSS is set; ETHTOOL_SRXFH needs a similar code path to handle the
FLOW_RSS case so that ethtool can set the flow hash for custom RSS
contexts (if supported by the driver).
The copy code from ETHTOOL_GRXFH has been pulled out in to a helper so
that it can be called in both ETHTOOL_{G,S}RXFH code paths.

Marc Kleine-Budde <mkl@pengutronix.de> says:
Traditionally USB drivers used netif_rx to pass the received CAN
frames/skbs to the network stack. In netif_rx() the skbs are queued to
the local CPU. If IRQs are handled in round robin, CAN frames may be
delivered out-of-order to user space.
To support devices without timestamping the TX path of the rx-offload
helper is cleaned up and extended:
- rename rx_offload_get_echo_skb() ->
can_rx_offload_get_echo_skb_queue_timestamp()
- add can_rx_offload_get_echo_skb_queue_tail()
The last patch converts the gs_usb driver to NAPI with the rx-offload
helper.

To avoid out-of-order reception convert the driver from netif_rx() to

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.

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

net: stmmac: Increase clk_ptp_ref rate
This series aims to increase the clk_ptp_ref rate to get the best
possible PTP timestamping resolution possible. Some modified disclosure
about my development/testing process from the RFC/RFT v1 follows.
Disclosure: I don't know much about PTP beyond what you can google in an
afternoon, don't have access to documentation about the stmmac IP,
and have only tested that (based on code comments and git commit
history) the programming of the subsecond register (and the clock rate)
makes more sense with these changes. Qualcomm has tested a similar
change offlist, verifying PTP more formally as I understand it.
The last version was an RFC/RFT, but I didn't get a lot of confirmation
that doing patch 3 in that series (essentially setting clk_ptp_ref to
whatever its max value is) for the whole stmmac ecosystem was a safe
idea. So I am erring on the side of caution and doing this for the
Qualcomm platform only. See v1 for an approach that would apply to
all stmmac platform drivers with clk_ptp_ref.

Qualcomm clocks can set their frequency to a variety of levels
generally. Let's use the max for clk_ptp_ref to ensure the best

Without this, the default value of the clock is used. For sa8775p-ride
this is 19.2 MHz, far less than the 230.4 MHz possible.

TLS resets the protocol operations, so the read_sock() callback might
be changed, too.
In this case using sock->ops->readsock() in tls_strp_read_copyin() will
enter an infinite recursion if the read_sock() callback is calling
tls_rx_rec_wait() which will call into sock->ops->readsock() via
tls_strp_read_copyin().
But as tls_strp_read_copyin() is supposed to produce data from the
consumed socket and that socket is always a TCP socket we can call
tcp_read_sock() directly without having to deal with callbacks.
