2013-04-18dpaa_eth: Delay buffer pool seeding for private portsIoana Radulescu
Until now, all private ports had to be configured to use the same buffer size, as they all share a common buffer pool. Create the framework for working with different buffer sizes on the private ports; a single, common buffer pool is still used by all private ports. The pool is seeded with buffers large enough to accomodate frames for all private ports. In order to be able to compute the largest needed buffer size, the buffer pool seeding is delayed until the first private interface is raised. Temporarily disable the boot-time ethernet unit test, which requires the use of the common buffer pool.

2013-04-08dpaa_eth: Linearize skbs with at least 16 fragsBogdan Hamciuc
Egress skbuffs can have up to (at least) 18 frags, a value which FMan does not support. So far we hadn't hit such a test case and we overlooked the problem. But netperf with TCP_SENDFILE and a - rather artificial, yet legal - "-m 18" option generates fragmented traffic with more than 16 fragments, causing problems on the egress (Tx, Tx Confirm) leg. We must therefore linearize outgoing skbuffs which are more fragmented than we can handle. Code rearrangements attempt to compensate the slight performance impact of the newly-added conditionals. So far, TCP tests with the "-m" flag are the only known case of heavy fragmentation given our supported MTU range (<=9578), so this patch is unlikely to cause performance issues in our benchmarks.

2013-04-08dpaa_eth: Remove congestion group initialization for mac-less interfacesCristian Sovaiala
MAC-less devices initialize their own RX frame queues, assuming that the TX queues will be initialized by the other partition. We cannot rely on the second partition to place the TX queues of the first partition into congestion groups because the congestion interrupt will then be received by the second partition instead of the partition enqueueing the frames (in this case the first partition). Supporting congestion on MAC-less devices would involve too much code and device tree changes so we simply use taildrop mechanism for now.

2013-04-08dpaa_eth: Put TxConf FQs in the default pool channelBogdan Hamciuc
Up until now, each Tx Confirmation FQ would stay in the dedicated channel of the CPU "owning" its peer Tx FQ. Although that boosts L2 statistics, in the end the Rx endpoint has to spend more time in Rx softirqs, thereby starving the userspace application listening on a UDP socket. So in our non-preemptible, default kernel configuration, more was in fact less, because the L4 throughput ("the goodput") was lower. By moving the Tx Confirmation FQs into the default pool channel, we get slightly lower L2 performance, but better L4 figures. This is especially the case for "power-deprived" configurations, such as 4-core setups with small-sized UDP traffic.

2013-04-08dpaa_eth: Fix buffer recycling for FMANv3Ioana Radulescu
On FMANv3 the decision to either confirm a frame or have the Tx frame buffers freed by FMan can only be made on a per-FQ basis (as opposed to FMANv2, where this could be decided for each frame). In order to accomodate this, create for each ordinary Tx queue a "shadow" Tx recycle queue where only frames that need to be recycled will be enqueued; frames for which we expect confirmation will still be sent on the ordinary Tx queues. Code is compiled in only for FMan v3 platforms, and only if "Optimized for forwarding" option has been chosen in Kconfig.
