net: xdp: pass full flags to xdp_update_skb_shared_info()
xdp_update_skb_shared_info() needs to update skb state which
was maintained in xdp_buff / frame. Pass full flags into it,
instead of breaking it out bit by bit. We will need to add
a bit for unreadable frags (even tho XDP doesn't support
those the driver paths may be common), at which point almost
all call sites would become:
xdp_update_skb_shared_info(skb, num_frags,
sinfo->xdp_frags_size,
MY_PAGE_SIZE * num_frags,
xdp_buff_is_frag_pfmemalloc(xdp),
xdp_buff_is_frag_unreadable(xdp));
Keep a helper for accessing the flags, in case we need to
transform them somehow in the future (e.g. to cover up xdp_buff
vs xdp_frame differences).
While we are touching call callers - rename the helper to
xdp_update_skb_frags_info(), previous name may have implied that
it's shinfo that's updated. We are updating flags in struct sk_buff
based on frags that got attched.
