2013-07-11dpa_offload: Add protection against concurrent HM ops runtime modificationsMarian Chereji
When modifying a header manipulation operation at runtime, the DPA Classifier uses the FMD call FM_PCD_ManipNodeReplace. This function locks the entire PCD and will fail if the PCD is already locked (it is not a blocking function). The parallel access protection mechanism in DPA Classifier would only protect against parallel access ON THE SAME MANIP NODE. It used to ALLOW parallel access on DIFFERENT HM nodes, but this will fail due to the locking system in the FMD. This patch updates the locking mechanism in DPA Classifier for the HM runtime modification functions so that a single call to FM_PCD_ManipNodeReplace can happen at any one time.

When shared descriptor is updated by the driver application, it needs to be copied again into driver context and pre-header should also be updated.

fixed-link does not work in 3.8.x, to make XFI work which has no PHY, it's actually not necessary to use fixed-link, otherwise there will be more work and code changes to make fixed-link work in 3.8.x. For now, if driver does not find the phy_node of MAC, just set the mac_dev->phy_dev = NULL and return 0; we can get XFI work and this won't break other ethernet ports. It's only for SDK1.4, if we decide to bring fixed-link back, it can be done after SDK1.4.

2013-05-31dpaa_eth: Create TxConf FQs with HOLDACTIVE flagBogdan Hamciuc
Tx Confirmation FQs tend, with originating traffic, to generate a high number of portal interrupts. A machine doing only TCP transmits may well end up having more portal interrupts than its Rx peer. By setting the HOLDACTIVE flag on the Tx Confirmation FQs, we significantly reduce the number of portal interrupts in termination tests. The quantitative effect is anywhere between 2% and 4% on Tx-mainly cores (most visible in UDP_STREAM tests, least visible on TCP_STREAM).
