Subject: [PATCH 5/8] NTB: perf: Don't require one more memory window than peer
Date: Fri,  8 Jun 2018 18:08:16 -0600	[thread overview]
Message-ID: <20180609000819.13883-7-logang@deltatee.com> (raw)
In-Reply-To: <20180609000819.13883-1-logang@deltatee.com>

NTB Perf should not require more than one memory window per peer. This
was probably an off-by-one error.

Fixes: 5648e56d03fa ("NTB: ntb_perf: Add full multi-port NTB API support")
