From c51a744a28bad6faec696b56c176519bea0e73bc Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Sat, 30 Jun 2018 02:50:28 +0200 Subject: [PATCH] selftests: mlxsw: Add target for router test on spectrum IPv4 routes in Spectrum are based on the kvd single-hash, but as it's a hash we need to assume we cannot reach 100% of its capacity. Add a wrapper that provides us with good/bad target numbers for the Spectrum ASIC.
