Implements the new netdev op to allow user to enable/disable the ability of a specific VF to query its RSS Indirection Table and an RSS Hash Key. This patch limits the new feature support to 82599 and x540 devices only. Support for other devices will be added later.

This patch is a preparation for enablement of ethtool RSS indirection table and hash key querying. We don't want to read registers every time the RSS info is queried. Therefore we will store its current content in the arrays in the adapter struct and will read it from there (instead of from registers) when requested. Will change the code that writes the indirection table and hash key into the HW registers to take its content from these arrays. This will also simplify the indirection table updating ethtool callback implementation in the future.

This patch removes some dead code from the cleanup path for ixgbe. Setting and clearing the flag doesn't do anything since all we are doing is setting the flag, scheduling NAPI, clearing the flag and then letting netpoll do the polling cleanup. As such it doesn't make much sense to have it there. This patch also removes one minor white-space error.

This change addresses several issues in the current ixgbe implementation of busy poll sockets. First was the fact that it was possible for frames to be delivered out of order if they were held in GRO. This is addressed by flushing the GRO buffers before releasing the q_vector back to the idle state. The other issue was the fact that we were having to take a spinlock on changing the state to and from idle. To resolve this I have replaced the state value with an atomic and use atomic_cmpxchg to change the value from idle, and a simple atomic set to restore it back to idle after we have acquired it. This allows us to only use a locked operation on acquiring the vector without a need for a locked operation to release it.

Time stamping resources are per-interface so there is no need to keep separate last_rx_timestamp for each Rx ring, move last_rx_timestamp to the adapter structure. With last_rx_timestamp inside adapter, ixgbe_ptp_rx_hwtstamp() inline function is reduced to a single if statement so it is no longer necessary. If statement is placed directly in ixgbe_process_skb_fields() fixing likely/unlikely marking. Checks for q_vector or adapter to be NULL are superfluous.

There needs to be an indication when the service task has been initialized. This is because register access prior to that time can detect a removal and attempt to schedule the service task. Adding the __IXGBE_SERVICE_INITED bit allows this to be checked and if not set prevent the service task scheduling. By checking for a removal right after initialization, the probe can be failed at that point without getting the service task involved.

The ixgbe driver allocates pages for its receive rings. It currently uses 512 pages, regardless of page size. During receive handling it adds the unused part of the page back into the rx ring, avoiding the need for a new allocation. On a ppc64 box with 64 threads and 64kB pages, we end up with 512 entries * 64 rx queues * 64kB = 2GB memory used. Even more of a concern is that we use up 2GB of IOMMU space in order to map all this memory. The driver makes a number of decisions based on if PAGE_SIZE is less than 8kB, so use this as the breakpoint and only allocate 128 entries on 8kB or larger page sizes.

ixgbe_napi_disable_all calls napi_disable on each queue, however the busy polling code introduced a local_bh_disable()d context around the napi_disable. The original author did not realize that napi_disable might sleep, which would cause a sleep while atomic BUG. In addition, on a single processor system, the ixgbe_qv_lock_napi loop shouldn't have to mdelay. This patch adds an ixgbe_qv_disable along with a new IXGBE_QV_STATE_DISABLED bit, which it uses to indicate to the poll and napi routines that the q_vector has been disabled. Now the ixgbe_napi_disable_all function will wait until all pending work has been finished and prevent any future work from being started.

This patch fixes a lockdep issue created due to ixgbe_ptp_stop always running cancel_work_sync even if the work item had not been created properly with INIT_WORK. This is caused because ixgbe_ptp_stop did not check to actually ensure PTP was running first. The new implementation introduces a state in the &adapter->state field which is used to indicate that PTP is running. (This replaces the IXGBE_FLAG2_PTP_ENABLED field). This state will use the atomic set_bit, test_bit, and test_and_clear_bit functions. ixgbe_ptp_stop will check to ensure that PTP was enabled, (and if not, it will not attempt to do any cleanup work from ixgbe_ptp_init).
