From ea9384f31369db7f142f2b15f75a02c998062416 Mon Sep 17 00:00:00 2001 From: Sriharsha Basavapatna Date: Sun, 9 Oct 2016 09:58:49 +0530 Subject: [PATCH] be2net: Provide an alternate way to read pf_num for BEx chips Orabug: 25570957 The driver gets the pf_num for Skyhawk and Lancer using GET_FUNC_CONFIG FW command. But since that command is not supported in BEx, we need to get it from some other command. Otherwise TPE recovery would fail since all NIC PFs would end up with a func num of 0. There's a pci function number field in the response of GET_CNTL_ATTRIBUTES command that can be read to get the same info for BEx adapters. Signed-off-by: Sriharsha Basavapatna Signed-off-by: David S.
