Message-ID: <1462973785-32532-4-git-send-email-Yuval.Mintz@qlogic.com>
Date: Wed, 11 May 2016 16:36:14 +0300
From: Yuval Mintz <Yuval.Mintz@...gic.com>

Subject: [PATCH net-next v2 03/14] qed: Introduce VFs
This adds the qed VFs for the first time -
The vfs are limited functions, with a very different PCI bar structure
[when compared with PFs] to better impose the related security demands
associated with them.
This patch includes the logic neccesary to allow VFs to successfully probe
[without actually adding the ability to enable iov].
This includes diverging all the flows that would occur as part of the pci
probe of the driver, preventing VF from accessing registers/memories it
can't and instead utilize the VF->PF channel to query the PF for needed
information.
