2015-07-23ixgbevf: add support for reporting RSS key and hash table for X550Emil Tantilov
This patch extends the reporting of the RSS key and hash table by adding support for X550 VFs. The difference is that X550 VFs have their own registers for RSS key and indirection table, so there is no need to query the PF. The RSS key and indirection table are stored in the adapter structure during the configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for reporting. The logic for writing VFRETA is also changed to make sure that the indirection table is reported correctly. In addition this patch adds defines for the VFRETA entries and number of VFRSSRK registers as well as some whitespace cleanups.

2015-04-11ixgbevf: Add the appropriate ethtool ops to query RSS indirection table and keyVlad Zolotarov
Added get_rxfh_indir_size, get_rxfh_key_size and get_rxfh ethtool_ops callbacks implementations. This enables the ethtool's "-x" and "--show-rxfh[-indir]" options for VF devices. This patch adds the support for 82599 and x540 devices only. Support for other devices will be added later.

Fix the code comments to align with drivers/net/ code commenting style, as well as whitespace issues. The whitespace issues resolve checkpatch errors, like lines exceeding 80 chars (except for strings) and the use of tabs where possible.

2014-01-17ixgbevf: remove counters for Tx/Rx checksum offloadEmil Tantilov
This patch removes the Tx/Rx counters for checksum offload. The Tx counter was never updated and the Rx counter is of limited use. This is in effort to clean up the counters and make them consistent with the counters shown by ixgbe. Also this patch removes some members of the adapter structure that were never used and shuffles others to reduce number of holes. before: /* size: 1568, cachelines: 25, members: 48 */ /* sum members: 1519, holes: 10, sum holes: 43 */ /* padding: 6 */ /* last cacheline: 32 bytes */ after: /* size: 1480, cachelines: 24, members: 43 */ /* sum members: 1479, holes: 1, sum holes: 1 */ /* last cacheline: 8 bytes */ Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

2014-01-17ixgbevf: make use of the dev pointer in the ixgbevf_ring structEmil Tantilov
This patch cleans up the code by removing the adapter structure as parameter from multiple functions. The adapter structure was previously being used to access the dev pointer, but this can also be done via the ixgbevf_ring structure. This way we can drop the adapter as parameter from these functions. This patch also includes small cleanups in some error code paths.

2013-10-29ixgbevf: Add zero_base handler to network statisticsDon Skidmore
This patch removes the need to keep a zero_base variable in the adapter structure. Now we just use two different macros to set the non-zero and zero base. This adds to readability and shortens some of the structure initialization under 80 columns. The gathering of status for ethtool was slightly modified to again better fit into 80 columns and become a bit more readable.

2012-07-18ixgbevf: Fix multiple issues in ixgbevf_get/set_ringparamAlexander Duyck
In ixgbevf_get_ringparam we could run into a NULL pointer dereference if the rings were not allocated when we attempted the call. To prevent that we can just access the tx/rx_ring_count values instead of attempting to access the rings to get the count. This change corrects a memory leak and memory corruption in ixgbevf_set_ringparam. The memory leak was due to us not freeing the resources from the ring before overwriting them. This change corrects the memory leak by making certain to call ixgbe_free_tx/rx_resources on the rings prior to freeing them. The memory corruption was because we were replacing the rings but not updating the q_vectors. It addresses the memory corruption by leaving the rings in place and instead just copying the contents of the new rings into the existing rings.

2012-07-17ixgbevf: Move Tx clean-up into NAPI contextAlexander Duyck
Currently the VF driver is processing all of the transmits in interrupt context. This can be messy since the Rx is all handled in NAPI and this may result in interrupts being disabled. In order to resolve this move all of the Tx packet processing into NAPI and combine all of the interrupt and polling routines into just a pair of functions.
