Re: [PATCHv7 bpf-next 0/4] xdp: extend xdp_redirect_map with broadcast support

Hi,

This patchset is a new implementation for XDP multicast support based
on my previous 2 maps implementation[1]. The reason is that Daniel think
the exclude map implementation is missing proper bond support in XDP
context. And there is a plan to add native XDP bonding support. Adding a
exclude map in the helper also increase the complex of verifier and has
draw back of performace.

The new implementation just add two new flags BPF_F_BROADCAST and
BPF_F_EXCLUDE_INGRESS to extend xdp_redirect_map for broadcast support.

With BPF_F_BROADCAST the packet will be broadcasted to all the interfaces
in the map. with BPF_F_EXCLUDE_INGRESS the ingress interface will be
excluded when do broadcasting.

Alright, I'm out of things to complain about - thanks for sticking with
it! :)
