2015-04-14fm10k: use hw->mac.max_queues for statsJeff Kirsher
Even though it shouldn't strictly matter, don't count queue stats higher than the max_queues value stored for this mac. This ensures that we don't attempt to check queues which don't belong to use in VFs. This shouldn't be a visible change, as the VFs should see zero for queues which don't belong to them.

2015-04-14fm10k: only show actual queues, not the maximum in hardwareJeff Kirsher
Currently, we show statistics for all 128 queues, even though we don't necessarily have that many queues available especially in the VF case. Instead, use the hw->mac.max_queues value, which tells us how many queues we actually have, rather than the space for the rings we allocated. In this way, we prevent dumping statistics that are useless on the VF.

The were several functions which had parameters which were never or sometimes used in functions. To resolve possible compiler warnings, use __always_unused or __maybe_unused kernel macros to resolve.

2014-12-08ethtool: Support for configurable RSS hash functionEyal Perry
This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.

2014-09-23fm10k: Add support for PTPAlexander Duyck
This change adds support for the Linux PTP Hardware clock and timestamping functionality provided by the hardware. There are actually two cases that this timestamping is meant to support. The first case would be an ordinary clock scenario. In this configuration the host interface does not have access to BAR 4. However all of the host interfaces should be locked into the same boundary clock region and as such they are all on the same clock anyway. With this being the case they can synchronize among themselves and only need to adjust the offset since they are all on the same clock with the same frequency. The second case is a boundary clock scenario. This is a special case and would require both BAR 4 access, and a means of presenting a netdev per boundary region. The current plan is to use DSA at some point in the future to provide these interfaces, but the DSA portion is still under development.

2014-09-23fm10k: Add support for VFAlexander Duyck

2014-09-23fm10k: Add support for multiple queuesAlexander Duyck
This patch takes the driver from supporting a single queue to supporting multiple queues. The upper queue limit for the PF is 128 queues and the upper limit for the VF is (128 / num_vfs) rounded down to nearest power of 2.
