Merge branch 'support-skf_net_off-and-skf_ll_off-on-skb-frags'
Willem de Bruijn says:
====================
support SKF_NET_OFF and SKF_LL_OFF on skb frags
From: Willem de Bruijn <willemb@google.com>
Address a longstanding issue that may lead to missed packets
depending on system configuration.
Ensure that reading from packet contents works regardless of skb
geometry, also when using the special SKF_.. negative offsets to
offset from L2 or L3 header.
Patch 2 is the selftest for the fix.
v2->v3
- do not remove bpf_internal_load_pointer_neg_helper, because it
is still used in the sparc32 JIT
v1->v2
- introduce bfp_skb_load_helper_convert_offset to avoid open
coding
- selftest: add comment why early demux must be disabled
