From fc0f39bcb50cd4a414ee5d5fef5208a7d04c4c32 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Thu, 12 Dec 2019 03:12:55 -0800 Subject: ice: Add code to keep track of current dflt_vsi We can't have more than one default VSI so prevent another VSI from overwriting the current dflt_vsi. This was achieved by adding the following functions: ice_is_dflt_vsi_in_use() - Used to check if the default VSI is already being used. ice_is_vsi_dflt_vsi() - Used to check if VSI passed in is in fact the default VSI. ice_set_dflt_vsi() - Used to set the default VSI via a switch rule ice_clear_dflt_vsi() - Used to clear the default VSI via a switch rule. Also, there was no need to introduce any locking because all mailbox events and synchronization of switch filters for the PF happen in the service task.
