One of the goals of FC-BB-5 was to be as nonintrusive as possible on initiators and targets, and therefore FIP VLAN discovery occurs in the native VLAN used by the initiator or target to exchange Ethernet traffic. The FIP VLAN discovery protocol is the only FIP protocol running on the native VLAN; all other FIP protocols run on the discovered FCoE VLANs. If an administrator has manually configured FCoE VLANs on ENodes and FCFs, there is no need to use this protocol. FIP and FCoE will run over the configured VLANs. An ENode without FCoE VLANs configuration would use this automated discovery protocol to discover over which VLANs FCoE is running. The ENode sends a FIP VLAN discovery request to a multicast MAC address called All-FCF-MACs, which is a multicast MAC address to which all FCFs listen. All FCFs that can be reached in the native VLAN of the ENode are expected to respond on the same VLAN with a response that lists one or more FCoE VLANs that are available for the ENode's VN_Port login. This protocol has the sole purpose of allowing the ENode to discover all the available FCoE VLANs. Now the ENode may enable a subset of these VLANs for FCoE Running the FIP protocol in these VLANs on a per VLAN basis. And FCoE data transactions also would occur on this VLAN. Hence, Except for FIP VLAN discovery, all other FIP and FCoE traffic runs on the selected FCoE VLAN. Its only the FIP VLAN Discovery protocol that is permitted to run on the Default native VLAN of the system. [**** NOTE ****] We are working on moving this feature definitions and functionality to libfcoe module. We need this patch to be approved, as Suse is looking forward to merge this feature in SLES 11 SP3 release. Once this patch is approved, we will submit patch which should move vlan discovery feature to libfoce.

| * | block: Remove some unnecessary bi_vcnt usageKent Overstreet2013-03-232-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More prep work for immutable bvecs/effecient bio splitting - usage of bi_vcnt has to be auditing, so getting rid of all the unnecessary usage makes that easier. Plus, bio_segments() is really what this code wanted, as it respects the current value of bi_idx.

Allegedly to improve performance but I don't really have good performance numbers (I might have lost the email) and I can't raise Kent today. I held this out of 3.9 and we could give it another cycle if it's all too late/scary. I ended up taking only the first two thirds of the AIO rotorooting. I left the percpu parts and the batch completion for later. - Linus * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (33 commits) aio: don't include aio.h in sched.h aio: kill ki_retry aio: kill ki_key aio: give shared kioctx fields their own cachelines aio: kill struct aio_ring_info aio: kill batch allocation aio: change reqs_active to include unreaped completions aio: use cancellation list lazily aio: use flush_dcache_page() aio: make aio_read_evt() more efficient, convert to hrtimers wait: add wait_event_hrtimeout() aio: refcounting cleanup aio: make aio_put_req() lockless aio: do fget() after aio_get_req() aio: dprintk() -> pr_debug() aio: move private stuff out of aio.h aio: add kiocb_cancel() aio: kill return value of aio_complete() char: add aio_{read,write} to /dev/{null,zero} aio: remove retry-based AIO ...
