This patchset contains XDP micro optimizations for the redirect core.
These are not functional changes.  The optimizations revolve around
getting the compiler to layout the code in a way that reflect how XDP
redirect is used.

Today the compiler chooses to inline and uninline (static C functions)
in a suboptimal way, compared to how XDP redirect can be used. Perf
top clearly shows that almost everything gets inlined into the
function call xdp_do_redirect.

The way the compiler chooses to inlines, does not reflect how XDP
redirect is used, as the compile cannot know this.

Applied, Thanks
