From 6d765c22d615bbe294d4a72fee7b3165b4e7dd97 Mon Sep 17 00:00:00 2001 From: vrindle Date: Fri, 28 Apr 2023 13:15:26 -0400 Subject: [PATCH] Update error messages to show why no interface is selected When the SRIOV network node state is not properly initialized it can hit the error "no supported NIC is selected by the nicSelector" even though the NIC may be indeed be selected. This commit updates the error message to ensure that if the user is configuring a NIC that is supported, then the error is because the SRIOV network node state is not properly initialized. --- pkg/webhook/validate.go | 44 +++++++++++++++++++++++++++--------- pkg/webhook/validate_test.go | 16 ++++++------- 2 files changed, 41 insertions(+), 19 deletions(-) diff --git a/pkg/webhook/validate.go b/pkg/webhook/validate.go index 91b3922fa..a9d617943 100644 --- a/pkg/webhook/validate.go +++ b/pkg/webhook/validate.go @@ -29,8 +29,8 @@ const ( ) var ( -
