[PATCH v4 1/1] xdp: Sample xdp program implementing ip forward

From: Christina Jacob Implements port to port forwarding with route table and arp table lookup for ipv4 packets using bpf_redirect helper function and lpm_trie map. Signed-off-by: Christina Jacob --- samples/bpf/Makefile | 4 + samples/bpf/xdp_router_ipv4_kern.c | 186

[PATCH v4 0/1] XDP program for ip forward

From: Christina Jacob The patch below implements port to port forwarding through route table and arp table lookup for ipv4 packets using bpf_redirect helper function and lpm_trie map. This has an improved performance over the normal kernel stack ip forward. Implementation details
