Date: Mon, 27 Jun 2011 12:44:01 -0500 From: Jon Mason <jdmason@...zu.us> To: Jeff Kirsher <jeffrey.t.kirsher@...el.com> Cc: e1000-devel@...ts.sourceforge.net, netdev@...r.kernel.org Subject: [PATCH 09/19] igb: remove unnecessary reads of PCI_CAP_ID_EXP The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it.
