As mentioned by Alexei last week in Budapest, it is a bit weird

Lets add percpu infra for tc actions and use it for gact mirred.
Before changes, my host with 8 RX queues was handling 5 Mpps with gact,
and more than 11 Mpps after.
Final step for gact RCU operation :
1) Use percpu stats
2) update lastuse only every clock tick to avoid false sharing
3) Remove spinlock acquisition, as it is no longer needed.
Since this is the last contended lock in packet RX when tc gact is used,
this gives impressive gain.

First step for gact RCU operation :
Instead of testing if tcfg_pval is zero or not, just make it 1.
No change in behavior, but slightly faster code.
The smp_rmb()/smp_wmb() barriers, while not strictly needed at this
stage are added for upcoming spinlock removal.

Second step for gact RCU operation :

I ran some tests and after setting the ip route change quickack 1
knob there were still many delayed ACKs sent. This occured
because when icsk_ack.quick=0 the !icsk_ack.pingpong value is
subsequently ignored as tcp_in_quickack_mode() checks both these
values. The condition for a quick ack to
Frag needed should be sent only if the inner header asked
to not fragment. Currently fragmentation is broken if the
tunnel has df set, but df was not asked in the original
packet. The tunnel's df needs to be still checked to update
internally the pmtu cache.
Commit 23a3647bc4f93bac broke it, and
As mentioned by Alexei last week in Budapest, it is a bit weird
to take a spinlock in order to drop a packet in a tc filter...
Lets add percpu infra for tc actions and use it for gact mirred.
Before changes, my host with 8 RX queues was handling 5 Mpps with gact,
and more than 11 Mpps after.
qdisc_bstats_update_cpu() and other helpers were added to support
percpu stats for qdisc.
We want to add percpu stats for tc action, so this patch add common
helpers.
qdisc_bstats_update_cpu() is renamed to qdisc_bstats_cpu_update()
qdisc_qstats_drop_cpu() is renamed to qdisc_qstats_cpu_drop()
Reuse existing percpu infrastructure John Fastabend added for qdisc.
This patch adds a new cpustats parameter to tcf_hash_create() and all
actions pass false, meaning this patch should have no effect yet.

First step for gact RCU operation :
Instead of testing if tcfg_pval is zero or not, just make it 1.
No change in behavior, but slightly faster code.
The smp_rmb()/smp_wmb() barriers, while not strictly needed at this
stage are added for upcoming spinlock removal.

Second step for gact RCU operation :
We want to get rid of the spinlock protecting gact operations.
Stats (packets/bytes) will soon be per cpu.
gact_determ() would not work without a central packet counter,
so lets add it for this mode.

Allow tasks to have a default device index for binding sockets. If set
the value is passed to all AF_INET/AF_INET6 sockets when they are created.
The task setting is passed parent to child on fork, but can be set or
changed after task creation using prctl (if task has CAP_NET_ADMIN
permissions).
This driver borrows heavily from IPvlan and teaming drivers.
Routing domains (VRF-lite) are created by instantiating a device
and enslaving all routed interfaces that participate in the domain.
As part of the enslavement, all local routes pointing to enslaved
devices are re-pointed to the vrf
With the following tweaks to the IPv4 stack:
- enslaving devices to a VRF device automatically moves routes to the
VRF table; removing the VRF master moves routes back to the main table
- the following use cases work for both Rx and Tx:
+ ICMP (ping -I vrf-device ip)
+ TCP server and client
