Sontu Mazumdar reports incorrect matching in the pipapo set type. First patch adds debug infrastructure (conditional for CONFIG_DEBUG_NET) to add rudimentary avx register tracking. Second patch is the actual fix. Third patch adds a test case. I checked that selftest passes with all three patches applied, that the new selftest fails without the fix and that the register tracking added in patch 1 also produces a WARN splat.
