+Subject: [PATCH] firewire: wait until PHY configuration packet was transmitted
+To: linux1394-devel at lists.sourceforge.net
+cc: linux-kernel at vger.kernel.org,
+ Jarod Wilson <jwilson at redhat.com>
+
+We now exit fw_send_phy_config /after/ the PHY config packet has been
+transmitted, instead of before. A subsequent fw_core_initiate_bus_reset
+will therefore not overlap with the transmission. This is meant to make
+the send PHY config packet + reset bus routine more deterministic.
