[NET]: Add const markers to various variables.
the patch below marks various variables const in net/; the goal is to move them to the .rodata section so that they can't false-share cachelines with things that get written to, as well as potentially helping gcc a bit with optimisations. (these were found using a gcc patch to warn about such variables) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: David S. Miller <davem@davemloft.net>
