From ab6dc30da55d262c54ae12e47e4a2e4372e39fbf Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Wed, 6 Apr 2011 23:24:42 +0000 Subject: mlx4: Sensing link type at device initialization When bringing the port up, performing a SENSE_PORT command To try and check to which physical link type (IB or Ethernet) the physical port is connected. In case there is no valid link partner, the port will come up as its supported default. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.
