bpf: Clear skb->tstamp in bpf_redirect when necessary
Redirecting a packet from ingress to egress by using bpf_redirect breaks if the egress interface has an fq qdisc installed. This is the same problem as fixed in 'commit 8203e2d8 ("net: clear skb->tstamp in forwarding paths") Clear skb->tstamp when redirecting into the egress path. Fixes: 80b14dee ("net: Add a new socket option for a future transmit time.") Fixes: fb420d5d ("tcp/fq: move back to CLOCK_MONOTONIC") Signed-off-by:Lorenz Bauer <lmb@cloudflare.com> Signed-off-by:
