This allows NIC's XDP to redirect packets to veth. The destination veth
device enqueues redirected packets to the napi ring of its peer, then
they are processed by XDP on its peer veth device.
This can be thought as calling another XDP program by XDP program using

We are going to add kern_flags field in redirect_info for kernel
internal use.
In order to avoid function call to access the flags, make redirect_info
accessible from modules. Also as it is now non-static, add prefix bpf_
to redirect_info.

This is preparation for XDP TX and ndo_xdp_xmit.
This allows napi handler to handle xdp_frames through xdp ring as well

Move XDP and napi related fields in veth_priv to newly created veth_rq
structure.
When xdp_frames are enqueued from ndo_xdp_xmit and XDP_TX, rxq is
selected by current cpu.
When skbs are enqueued from the peer device, rxq is one to one mapping
of its peer txq. This way we

This is the basic implementation of veth driver XDP.
Incoming packets are sent from the peer veth device in the form of skb,
so this is generally doing the same thing as generic XDP.
This itself is not so useful, but a starting point to implement other
useful veth XDP

All oversized packets including GSO packets are dropped if XDP is
enabled on receiver side, so don't send such packets from peer.
Drop TSO and SCTP fragmentation features so that veth devices themselves
segment packets with XDP enabled. Also cap MTU accordingly.

We need some mechanism to disable napi_direct on calling

This patch set introduces driver XDP for veth.
Basically this is used in conjunction with redirect action of another XDP
program.
NIC ---> veth===veth
(XDP) (redirect)(XDP)
In this case xdp_frame can be forwarded to the peer veth without
modification,
rhashtable_lookup() can return NULL. so that NULL pointer
check routine should be added.
