HTB doesn't scale well because of contention on a single lock, and it
also consumes CPU. This patch adds support for offloading HTB to
hardware that supports hierarchical rate limiting.
This solution addresses two main problems of scaling HTB:
1. Contention by flow classification. Currently the f

This commit adds support for HTB offload in the mlx5e driver.
Performance:
NIC: Mellanox ConnectX-6 Dx
CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz (24 cores with HT)
100 Gbit/s line rate, 500 UDP streams @ ~200 Mbit/s each
48 traffic classes, flower used for steering
No shaping (rat
This commit adds support for statistics of offloaded HTB. Bytes and
packets counters for leaf and inner nodes are supported, the values are
taken from per-queue qdiscs, and the numbers that the user sees should
have the same behavior as the software (non-offloaded) HTB.
Signed-off-by: Maxim Mikity
The existing qdiscs that set TCQ_F_MQROOT don't use sch_tree_lock.
However, hardware-offloaded HTB will start setting this flag while also
using sch_tree_lock.
The current implementation of sch_tree_lock basically locks on
qdisc->dev_queue->qdisc, and it works fine when the tree is attached to
som
This series adds support for HTB offload to the HTB qdisc, and adds
usage to mlx5 driver.
The previous RFCs are available at [1], [2].
The feature is intended to solve the performance bottleneck caused by
the single lock of the HTB qdisc, which prevents it from scaling well.
The HTB algorithm its
This commit adds support for configuring HTB in offload mode. HTB
offload eliminates the single qdisc lock in the datapath and offloads
the algorithm to the NIC. The new 'offload' parameter is added to
enable this mode:

The connector driver never modifies any cb_id passed to it, so add a const
qualifier to those arguments so callers can declare their struct cb_id as a

This series include two fixes patches for vhost_net.

vhost_net: fix ubuf refcount incorrectly when sendmsg fails
vhost_net: fix high cpu load when sendmsg fails

Currently the vhost_zerocopy_callback() maybe be called to decrease
the refcount when sendmsg fails in tun. The error handling in vhost
handle_tx_zerocopy() will try to decrease the same refcount again.
This is wrong. To fix this issue, we only call vhost_net_ubuf_put()
when vq
From: Yunjian Wang
Currently we break the loop and wake up the vhost_worker when
sendmsg fails. When the worker wakes up again, we'll meet the
same error. This will cause high CPU load. To fix this issue,
we can skip this description by ignoring the error. When we
exceeds sndbuf, the return value

Without this change the driver tries to allocate too many queues,
breaching the number of available msi-x interrupts on machines
with many logical cpus and default adapter settings:
Insufficient resources for 12 XDP event queues (24 other channels, max 32)
Which in turn triggers EINVAL on XDP pro

The intention of the err_expr cleanup path is to iterate over the
allocated expr_array objects and free them, starting from i - 1 and
working down to the start of the array. Currently the loop counter
is being incremented instead of decremented and also the index i is
being u

Currently the null check on a newly allocated skb is missing and
this can lead to a null pointer dereference is the allocation fails.
Fix this by adding a null check and returning -ENOMEM.
