Message-ID: <6ec19d49-d421-4b32-8ae9-127488429f65@CMEXHTCAS1.ad.emulex.com> Date: Sat, 20 Oct 2012 21:33:37 +0530 From: Padmanabh Ratnakar <padmanabh.ratnakar@...lex.com> To: <netdev@...r.kernel.org> CC: Padmanabh Ratnakar <padmanabh.ratnakar@...lex.com> Subject: [PATCH net-next 09/14] be2net: Fix unnecessary delay in PCI EEH During PCI EEH, driver waits for all functions in the card. Wait is needed only once per card. Fix is to wait only for the first PCI function.
