From 5f61385d2ebc2bd62bc389c7da0d8d2f263be1eb Mon Sep 17 00:00:00 2001 From: Moni Shoua Date: Sun, 6 Dec 2015 18:07:41 +0200 Subject: net/mlx4_core: Keep VLAN/MAC tables mirrored in multifunc HA mode Due to HW limitations, indexes to MAC and VLAN tables are always taken from the table of the actual port. So, if a resource holds an index to a table, it may refer to different values during the lifetime of the resource, unless the tables are mirrored. Also, even when driver is not in HA mode the policy of allocating an index to these tables is such to make sure, as much as possible, that when the time comes the mirroring will be successful. This means that in multifunction mode the allocation of a free index in a port's table tries to make sure that the same index in the other's port table is also free.
