From b891b4dc1eed33543c5818dae43ce8bb55f2080c Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Fri, 9 Nov 2012 15:56:03 +0900 Subject: PCI: Fix bit definitions of PCI_EXP_LNKCAP2 register According to the PCIe 3.0 spec, PCI_EXP_LNKCAP2_SLS_2_5GB is 1st bit of PCI_EXP_LNKCAP2 register, not 0th bit. So, the bit definition of supported link speed vector should be fixed.
