From dbe413e3bb93e0634f6d8d00b01cda6f141e0acd Mon Sep 17 00:00:00 2001 From: Hadar Hen Zion Date: Thu, 18 Aug 2016 21:09:08 +0300 Subject: net/mlx5e: Retrieve the switchdev id from the firmware only once Avoid firmware command execution each time the switchdev HW ID attr get call is made. We do that by reading the ID (PF NIC MAC) only once at load time and store it on the representor structure. Signed-off-by: Hadar Hen Zion Signed-off-by: Saeed Mahameed Signed-off-by: David S.
