Subject: [PATCH] bonding: use pre-defined macro in bond_mode_name instead of magic number 0
Date: Wed, 24 Jul 2013 14:53:26 +0800	[thread overview]
Message-ID: <51EF79E6.9060309@gmail.com> (raw)

We have BOND_MODE_ROUNDROBIN pre-defined as 0, and it's the lowest mode number.
Use it to check the arg lower bound instead of magic number 0 in bond_mode_name.
