Magnus Karlsson 484b165306 xsk: Eliminate the lazy update threshold ... The lazy update threshold was introduced to keep the producer and consumer some distance apart in the completion ring. This was important in the beginning of the development of AF_XDP as the ring format as that point in time was very sensitive to the producer and consumer being on the same cache line. This is not the case anymore as the current ring format does not degrade in any noticeable way when this happens. Moreover, this threshold makes it impossible to run the system with rings that have less than 128 entries. So let us remove this threshold and just get one entry from the ring as in all other functions. This will enable us to remove this function in a later commit. Note that xskq_produce_addr_lazy followed by xskq_produce_flush_addr_n are still not the same function as xskq_produce_addr() as it operates on another cached pointer.
