Note that I am sending this to net-next as a patchset (not as a PR) _only_ because this is adding a new .ndo_fill_forward_path to netdev_ops. That's the only thing that is relevant to the Netdev core infrastructure IMO, and this new .ndo that is private, not exposed to userspace. Let's have a look at the diffstats again: include/linux/netdevice.h | 35 +++ include/net/netfilter/nf_flow_table.h | 43 +++- net/8021q/vlan_dev.c | 15 ++ net/bridge/br_device.c | 27 +++ net/core/dev.c | 46 ++++ net/netfilter/nf_flow_table_core.c | 51 +++-- net/netfilter/nf_flow_table_ip.c | 200 ++++++++++++++---- net/netfilter/nft_flow_offload.c | 159 +++++++++++++- .../selftests/netfilter/nft_flowtable.sh | 82 +++++++ 9 files changed, 598 insertions(+), 60 deletions(-) So this is adding _minimal_ changes to the NetDev infrastructure. Most of the code is an extension to the flowtable Netfilter infrastructure. And the flowtable is a cache since its conception. I am adding the .ndo indirection to avoid the dependencies with Netfilter modules, e.g. Netfilter could use direct reference to bridge function, but that would pull in bridge modules. > > What senior developers specifically you would like I should poke to > > get an acknowledgement on this to get this accepted of your > > preference? > > I don't want to make a list. Maybe netconf attendees are a safe bet? I have no idea who to ask to, traditionally it's the NetDev maintainer (AFAIK it's only you at this stage) that have the last word on something to get this merged. I consider all developers that have reviewed this patchset to be senior developers.
