Subject: [patch net 1/2] mlxsw: spectrum_router: Save requested prefix bitlist when creating tree
Date: Tue, 25 Oct 2016 11:25:56 +0200	[thread overview]
Message-ID: <1477387557-5048-2-git-send-email-jiri@resnulli.us> (raw)
In-Reply-To: <1477387557-5048-1-git-send-email-jiri@resnulli.us>

From: Jiri Pirko <jiri@mellanox.com>

Currently, the prefix bitlist is not saved for LPM trees, causing the
compare to always fail which causes the tree to be destroyed and created
for every inserted and removed FIB entry. So fix this by saving
the bitlist as it should have been done from the very beginning.
