I think what you're referring to here is the need for multiple QSBR variables,
yes?  I'm not sure thats, strictly speaking, a requirement.  It seems like its a
performance improvement, but I'm not sure thats the case (see performance
numbers below).

Regarding performance, we can't keep using raw performance as a trump card for
all other aspects of the DPDK.  This entire patch is meant to improve
performance, it seems like it would be worthwhile to gain the code consolidation
and reuse benefits for the minor performance hit.

Further to performance, I may be misreading this, but I ran the integrated
performance test you provided in this patch, as well as the benchmark tests for
liburcw (trimmed for easier reading here)

Perf test: 1 writer, 7 readers, 1 QSBR variable, 1 QSBR Query, Non-Blocking QSBR check
Following numbers include calls to rte_hash functions
Cycles per 1 update(online/update/offline): 813407
Cycles per 1 check(start, check): 859679


Both of these tests qsbr rcu in each library using 7 readers and 1 writer.  Its
a little bit of an apples to oranges comparison, as the tests run using slightly
different parameters, and produce different output statistics, but I think they
can be somewhat normalized.  Primarily the stat that stuck out to me was the
DPDK Cycles per 1 update statistic, which I believe is effectively the number of
cycles spent in the test / the number of writer updates.  On DPDK that number in
this test run works out to 813407.  In the liburcw test, it reports the total
number of ops (cycles), and the number of writes completed within those cycles.
If we do the same division there we get 185905218 / 264444 = 4484. I may be
misreading something here, but that seems like a pretty significant write side
performance improvement over this implementation.
