tcp_hdrlen is wasteful if you already have a pointer to struct tcphdr.
This splits the size calculation into a helper function that can be
used if a struct tcphdr is already available.

In order to support fast lookups for TCP sockets with SO_REUSEPORT,
the function that adds sockets to the listening hash set needs
to be able to check receive address equality. Since this equality
check is different for IPv4 and IPv6, we will need two different
socket hashing functions.
This patch adds inet6_hash identical to the existing inet_hash function
and updates the appropriate references. A following patch will
differentiate the two by passing different comparison functions to
__inet_hash.
Additionally, in order to use the IPv6 address equality function from
inet6_hashtables (which is compiled as a built-in object when IPv6 is
enabled) it also needs to be in a built-in object file as well. This
moves ipv6_rcv_saddr_equal into inet_hashtables to accomplish this.

In order to support fast reuseport lookups in TCP, the hash function
defined in struct proto must be capable of returning an error code.
This patch changes the function signature of all related hash functions
to return an integer and handles or propagates this return value at
all call sites.

Then you have a patch, by Simon Wunderlich, that

Lastly, Sven is also introducing two lockdep asserts in

packet: tpacket gso and csum offload
Extend PACKET_VNET_HDR socket option support to packet sockets with
memory mapped rings.
Patches 2 and 4 add support to tpacket_rcv and tpacket_snd.
Patch 1 prepares for this by moving the relevant virtio_net_hdr
logic out of packet_snd and packet_rcv into helper functions.
GSO transmission requires all headers in the skb linear section.
Patch 3 moves parsing of tx_ring slot headers before skb allocation
to enable allocation with sufficient linear size.
Changes
v1->v2:
- fix bounds checks:
- subtract sizeof(vnet_hdr) before comparing tp_len to size_max
- compare tp_len to size_max also with GSO, just do not truncate to MTU

Support socket option PACKET_VNET_HDR together with PACKET_TX_RING.
When enabled, a struct virtio_net_hdr is expected to precede the data
in the ring. The vnet option must be set before the ring is created.
The implementation reuses the existing skb_copy_bits code that is used
when dev->hard_header_len is non-zero. Move this ll_header check to
before the skb alloc and combine it with a test for vnet_hdr->hdr_len.
Allocate and copy the max of the two.

GSO packet headers must be stored in the linear skb segment.
Move tpacket header parsing before sock_alloc_send_skb. The GSO
follow-on patch will later increase the skb linear argument to
sock_alloc_send_skb if needed for large packets.
The header parsing code does not require an allocated skb, so is
safe to move. Later pass to tpacket_fill_skb the computed data
start and length.

and the new values can be used/seen after the bond's upped so it's not
necessary anymore to release all and enslave again to see the changes.

====================
Namespaceify more of the tcp sysctl knobs
This patch series continues making more of the tcp-related
sysctl knobs be per net-namespace. Most of these apply per
socket and have global defaults so should be safe and I
don't expect any breakages.
Having those per net-namespace is useful when multiple
containers are hosted and it is required to tune the
tcp settings for each independently of the host node.
I've split the patches to be per-sysctl but after
the review if the outcome is positive I'm happy
to either send it in one big blob or just.
