Pulled, thanks Daniel.
MMIO reads for remaining packets in queue occur (at least)twice per
invocation of netsec_process_rx(). We can use the packet descriptor to
identify if it's owned by the hardware and break out, avoiding the more
expensive MMIO read operations. This has a ~2% increase on the pps of the
Rx path when t
This patchset introduces some improvements on socionext netsec driver.
- patch 1/2, avoids unneeded MMIO reads on the Rx path
- patch 2/2, is adjusting the numbers of descriptors used
Changes since v1:
- Move dma_rmb() to protect descriptor accesses until the device
has updated the NETSEC_R
Increasing descriptors to 256 from 128 and adjusting the NAPI weight
to 64 increases performace on Rx by ~20% on 64byte packets

Series applied, thanks Jose.
The main motive of this patch is to lay down driver's
tc offload infrastructure in place.
With these changes tc can offload various supported flow
profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop
action. Dropped flows statistic is a global counter for
all the offloaded flows for drop acti
This patch adds support for dropping and redirecting
the flows based on destination IP in the packet.
This also moves the profile mode settings in their own
functions which can be used through tc flows in successive
patch.
For example -
ethtool -N p5p1 flow-type tcp4 dst-ip 192.168.40.100 action
This patch adds support for tc mqprio offload,
using this different traffic classes on the adapter
can be utilized based on configured priority to tc map.
For example -
tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3
This will cause SKBs with priority 0,1,2,3 to transmit
over tc 0,1,2,3 h
Hi David,
This patch series adds following support in drivers -
1. Egress mqprio offload.
2. Add destination IP based flow profile.
3. Ingress flower offload (for drop action).
Please consider applying this series to "net-next".

Add a new character 'f' which can be used to configure an Ethernet
controller to support Wake-on-LAN using filters programmed with the
ethtool::rxnfc and the special action -2 (wake-up filter). This is
useful in particular in the context of devices that must support wake-up
on more complex patterns
Hi John,
This patch series syncs up ethtool-copy.h to get the new definitions
required for supporting wake-on-LAN using filters: WAKE_FILTER and
RX_CLS_FLOW_WAKE and then updates the rxclass.c code to allow us to
specify action -2 (RX_CLS_FLOW_WAKE).
Let me know if you would like this to be done
Add the ability to program special filters using ethtool::rxnfc which
are meant to be used for wake-up purposes (in conjuction with
WAKE_FILTER) using the special action value: -2 (RX_CLS_FLOW_WAKE).

So, big packets are making it from the switch to the PC. But the small
ARP packets are not.

Hello,
I have been trying to test a sample AF_XDP program, but I have been

Hi Andres,
I tried your patches on Turris Mox with one 6190 marvell switch with
port 9 connected to CPU and port 10 to SFP cage.
Seems it works :)
Thank you.

In function map_seq_next() of kernel/bpf/inode.c,
the first key will be the "0" regardless of the map type.
This works for array. But for hash type, if it happens
key "0" is in the map, the bpffs map show will miss
some items if the key "0" is not the first element of
the first bucket.

Commit a26ca7c982cb ("bpf: btf: Add pretty print support to

This patch adds pretty print for hash and lru_hash maps.
The following example shows the pretty-print result of
a pinned hashmap:

Pretty print tests for hash/lru_hash maps are added in test_btf.c.
The btf type blob is the same as pretty print array map test.
The test result:
$ mount -t bpf bpf /sys/fs/bpf
$ ./test_btf -p
BTF pretty print array..OK
BTF pretty print hash..OK

You need to be careful here. Once of_mdiobus_register() is called, the
MDIO should be usable.
