Oftenly, introducing side effects on packet processing on the other half
of the stack by adjusting one of TX/RX via sysctl is not desirable.
There are cases of demand for asymmetric, orthogonal configurability.
This holds true especially for nodes where RPS for RFS usage on top is
configured and t

Networking stack accelerate vlan tag handling by
keeping topmost vlan header in skb. This works as
long as packet remains in OVS datapath. But during
OVS upcall vlan header is pushed on to the packet.
When such packet is sent back to OVS datapath, core
networking stack might not handle it correctly

After commit 73b62bd085f4737679ea9afc7867fa5f99ba7d1b ("virtio-net:
remove the warning before XDP linearizing"), there's no users for
bpf_warn_invalid_xdp_buffer(), so remove it. This is a revert for
commit f23bc46c30ca5ef58b8549434899fcbac41b2cfc.

Thank you for your quick answer ! Allow me some days for this test :
1 - I am at work these days
2 - it has been a while since I have dealt with custom kernels, I am a
bit rusty, it will be good to review this topic

UNIX was not designed to stop you from doing stupid
When we send a packet for our own local address on a non-loopback interface
(e.g. eth0), due to the change had been introduced from commit 0b922b7a829c
("net: original ingress device index in PKTINFO"), the original ingress
device index would be set as the loopback interface. However, the packet
