Subject: [PATCH 10/10] Bluetooth: Enable option to configure Max Transmission value via sockopt
Date: Tue, 30 Mar 2010 15:52:40 -0300	[thread overview]
Message-ID: <1269975160-9994-10-git-send-email-padovan@profusion.mobi> (raw)
In-Reply-To: <1269975160-9994-9-git-send-email-padovan@profusion.mobi>

With the sockopt extension we can set a per-channel MaxTx value.
