Subject: [PATCH net-next 09/14] be2net: Fix unnecessary delay in PCI EEH
Date: Sat, 20 Oct 2012 21:33:37 +0530	[thread overview]
Message-ID: <6ec19d49-d421-4b32-8ae9-127488429f65@CMEXHTCAS1.ad.emulex.com> (raw)

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.
