2015-12-13fm10k: consistently refer to VLANs and VLAN IDsJacob Keller
Instead of using lowercase vlan, vid, or VID, always use VLAN or VLAN ID in comments when referring to VLANs. The original driver code was consistent, but recent patches have not been as consistent with this naming scheme.

2015-12-13Merge branch '1GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2015-12-12 This series contains updates to e1000, e1000e and igb. Joern Engel fixes up the e1000 driver to reduce scheduler latencies by making the eeprom read/write functions scheduler friendly by using a mutex lock instead of a spin lock. Todd adds code for igb to initialize the 88E1543 PHY properly. Then fixed igb to use the correct i210 register for EEMNGCTL, since the i210 has two EEPROM access registers (EEARBC and EEMNGCTL). Dmitry Vyukov provides a fix for e1000 to resolve a data race found with KernelThreadSanitizer (KTSAN), where no memory barriers were being used when buffers get recycled, so the recycled buffers can be corrupted. So use smp_store_release() to update tx_ring->next_to_clean and smp_load_acquire() to read tx_ring->next_to_clean to properly hand off buffers from e1000_clean_tx_irq() to e1000_xmit_frame(). Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr. Then cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and use io_addr() in more places so that we do not have to call E1000_REMOVED(). Janusz Wolak cleans up the e1000 driver by correcting warnings produced by checkpatch.pl for the driver. Jean Sacren provides several patches with general cleanups for e1000 and e1000e, which include code comment fix-ups and cleanup of local variables not needed. Dmitry Fleytman fixes a possible division by zero in the receive interrupt handler for e1000e when working without adaptive interrupt moderation, which is typically disabled on jumbo MTUs. Raanan increases the timeout of the polling bit due to timing changes to the ME firmware on a platform, so increase the timeout to 300ms. Added initial support for i219-LM, which is a LOM that will be available on systems with the Lewisburg Platform Controller HUB (PCH) chipset. Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data being NULL while adapter->vfs_allocated_count is non-zero. ==================== Signed-off-by: David S.

2015-12-13iwlwifi: replace d0i3_mode and wowlan_d0i3 with more generic variablesLuca Coelho
The d0i3_mode variable is used to distinguish between transports that handle d0i3 entry during suspend by themselves (i.e. the slave transports) and those which rely on the op_mode layer to do it. The reason why the former do it by themselves is that they need to transition from d0i3 in runtime_suspend into d0i3 in system-wide suspend and this transition needs to happen before the op_mode's suspend flow is called. The wowlan_d0i3 element is also a bit confusing, because it just reflects the wowlan->any value for the trans to understand. This is a bit unclear in the code and not generic enough for future use. To make it clearer and to generalize the platform power mode settings, introduce two variables to indicate the platform power management modes used by the transport. Additionally, in order not to take too big a step in one patch, treat this new variables semantically in the same way as the old d0i3_mode element, introducing a iwl_mvm_enter_d0i3_on_suspend() function to help with that. This commit also adds the foundation for a new concept where the firmware configuration state (i.e. D0, D3 or D0i3) is abstracted from the platform PM mode we are in (i.e. runtime suspend or system-wide suspend).

2015-12-13iwlwifi: mvm: close the SP if we send fewer frames than expected in SPEmmanuel Grumbach
When we have holes in the BA window, there might be frames that have been ACKed between the read and the right pointers. This means that these frames won't be scheduled again by the SCD and the firwmare won't see them. This invalidates the number of frames we tell the firmware to send. When we detect this case, tell mac80211 to close the SP and to send an EOSP so that the firmware can be in sync. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-12-12igb: fix NULL derefs due to skipped SR-IOV enablingJan Beulich
The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the right number of queues") causes VFs no longer getting set up, leading to NULL pointer dereferences due to the adapter's ->vf_data being NULL while ->vfs_allocated_count is non-zero. The first commit not only neglected the side effect of igb_sriov_reinit() that the second commit tried to account for, but also that of setting IGB_FLAG_HAS_MSIX, without which igb_enable_sriov() is effectively a no-op. Calling igb_{,re}set_interrupt_capability() as done here seems to address this, but I'm not sure whether this is better than sinply reverting the other two commits.

Well, now that hw_addr is NULL, the attempt to call pci_iounmap is obviously not going to go well. As suggested by Mark Rustad, do something similar to what ixgbe does, and save a copy of hw_addr as adapter->io_addr, so we can still call pci_iounmap on it on teardown. Additionally, for consistency, make the pci_iomap call assignment directly to io_addr, so map and unmap match.

But there are no memory barriers when buffers gets recycled, so the recycled buffers can be corrupted. Use smp_store_release to update tx_ring->next_to_clean and smp_load_acquire to read tx_ring->next_to_clean to properly hand off buffers from e1000_clean_tx_irq to e1000_xmit_frame.

2015-12-13iwlwifi: block the queues when we send ADD_STA for uAPSDEmmanuel Grumbach
We send an ADD_STA to instruct the firmware to release frames despite the peer being in PS. Since the ADD_STA command and the Tx frame that comes immediately afterwards can be reordered by the DMA engine, we need to block the Tx queues until the firmware replies with the ADD_STA response.

2015-12-13iwlwifi: trans: support a callback for ASYNC commandsEmmanuel Grumbach
This allows the op_mode to request from the transport to call a callback when an ASYNC commands is completed by the firmware. The same callback will be called for all the commands. Pass the command whose response triggers the callback as a parameter to the callback itself. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-13iwlwifi: pcie: allow the op_mode to block the tx queuesEmmanuel Grumbach
In certain flows (see next patches), the op_mode may need to block the Tx queues for a short period. Provide an API for that. The transport is in charge of counting the number of times the queues are blocked since the op_mode may block the queues several times in a row before unblocking them.

commit 9a4c830007817e ("iwlwifi: mvm: refactor d3 key update functions") refactored some code into iwl_mvm_wowlan_config_key_params() function, but the return value was never checked, and not all the function flows returned valid values. fix it.

2015-12-13iwlwifi: mvm: cleanup roc te on restart cleanupEliad Peller
iwl_mvm_restart_cleanup() calls ieee80211_remain_on_channel_expired() on cleanup, but it doesn't clean the actual roc time events, resulting in failure of further ROC attempts. Refactor iwl_mvm_stop_roc() a bit, and add a new function to only cleanup the roc time events (without sending further commands).

2015-12-13iwlwifi: mvm: set default new STA as non-aggregatedLiad Kaufman
When sending the first ADD_STA HCMD for a STA, the %add_modify field indicates an addition of a STA and not a modification of one. In such a case, all fields of the HCMD are used to initialize the corresponding fields in the FW, regardless of what bits are set in %modify_mask. Set the %tid_disable_tx field to mvm_sta->tid_disable_agg in iwl_mvm_sta_send_to_fw(). If the STA is only updated this will have no effect, but if it is added - it will make sure the STA starts with the correct queues - if any - configured as non-aggregated by default (until told otherwise).

Clean the whole mac filter list when resetting after an intermediate add or delete push to the firmware. The code had evolved from using a list from the stack to a heap allocation, but the memset() didn't follow the change correctly.
