[PATCH net-next 13/14] be2net: use adapter->flags to track SRIOV state
From: Sathya Perla <hidden>
Date: 2014-07-17 10:48:48
Subsystem:
emulex 10gbps nic be2, be3-r, lancer, skyhawk-r driver (be2net), networking drivers, the rest · Maintainers:
Ajit Khaparde, Sriharsha Basavapatna, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Vasundhara Volam <redacted>
The driver so far used adapter->num_vfs value to check if SR-IOV is enabled
or not. But, the patch bec84e6("create optimal number of queues on SR-IOV
config") changed this logic. The adapter->num_vfs value is validated and set
much before SR-IOV is enabled. So, we now use an explicit flag to track
SR-IOV enabled state.
