Date: Mon, 28 Sep 2015 17:55:28 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Jeff Kirsher <jeffrey.t.kirsher@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, john.ronciak@...el.com Subject: [net-next v2 0/6][pull request] Intel Wired LAN Driver Updates 2015-09-28 This series contains updates to i40e, i40evf and igb to resolve issues seen and reported by Red Hat. Kiran moves i40e_get_head() in preparation for the refactor of the Tx timeout logic, so that it can be used in other areas of the driver. Refactored the driver timeout logic by issuing a writeback request via a software interrupt to the hardware the first time the driver detects a hang. This was due to the driver being too aggressive in resetting a hung queue. Shannon adds the GRE protocol to the transmit checksum encoding. Anjali fixes an issue of forcing writeback too often, which caused us to not benefit from NAPI. We now disable force writeback in the clean routine for X710 and XL710 adapters. The X722 adapters do not enable interrupt to force a writeback and benefit from WB_ON_ITR and so force WB is left enabled for those adapters. Fixed a possible deadlock issue where sync_vsi_filters() can be called directly under RTNL or through the timer subtask without RTNL. So update the flow to see if we are already under RTNL before trying to grab it. Stefan Assmann provides a fix for igb where SR-IOV was not getting enabled properly and we ran into a NULL pointer if the max_vfs module parameter is specified. This is prevented by setting the IGB_FLAG_HAS_MSIX bit before calling igb_probe_vfs(). v2: added "i40e: Fix for recursive RTNL lock during PROMISC change" patch to the series, as it resolves another issues seen and reported by Red Hat. The following are changes since commit 34c2d9fb0498c066afbe610b15e18995fd8be792: bridge: Allow forward delay to be cfgd when STP enabled and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue master Anjali Singhai (2): i40e: Fix RS bit update in Tx path and disable force WB workaround i40e: Fix for recursive RTNL lock during PROMISC change Kiran Patil (2): i40e: Move i40e_get_head into header file i40e/i40evf: refactor tx timeout logic Shannon Nelson (1): i40e: add GRE tunnel type to csum encoding Stefan Assmann (1): igb: assume MSI-X interrupts during initialization drivers/net/ethernet/intel/i40e/i40e.h | 3 +- drivers/net/ethernet/intel/i40e/i40e_debugfs.c | 4 +- drivers/net/ethernet/intel/i40e/i40e_main.c | 291 ++++++++++++--------- drivers/net/ethernet/intel/i40e/i40e_txrx.c | 214 ++++++--------- drivers/net/ethernet/intel/i40e/i40e_txrx.h | 26 +- drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c | 8 +- drivers/net/ethernet/intel/i40evf/i40e_txrx.c | 94 +------ drivers/net/ethernet/intel/i40evf/i40e_txrx.h | 8 - drivers/net/ethernet/intel/igb/igb_main.c | 3 + 9 files changed, 296 insertions(+), 355 deletions(-) -- 2.4.3 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
