This series adds the BPF_F_INGRESS flag support to the redirect APIs.
Bringing the sockmap API in-line with the cls_bpf redirect APIs.

We add it to both variants of sockmap programs, the first patch adds
support for tx ulp hooks and the third patch adds support for the recv
skb hooks. Patches two and four add tests for the corresponding
ingress redirect hooks.

Follow on patches can address busy polling support, but next series
from me will move the sockmap sample program into selftests.

v2: added static to function definition caught by kbuild bot
