* | i40e: move i40e_vsi_config_rss below i40e_get_rss_aqJacob Keller2016-08-20
| | | | | | | | | | | | | | | | | | | | | | Move this function below the two functions related to configuring RSS via the admin queue. This helps co-locate the two functions, and made it easier to spot a bug in the first i40e_config_rss_aq function as compared to the i40e_get_rss_aq function.

Emil cleans up confusing amongst the users by making an error message into a debug message, since the TXDCTL.ENABLE (and comparable VFTXDCTL.ENABLE for ixgbevf) bit is set only when the transmit queue is actually enabled, which may not happen during the configure phase eve if we waited for it. Converts to using netdev_dbg() macro instead of our home brewed macro for ixgbevf. Converted the service task to use atomic bitwise operations when setting and checking reset requests to reduce the possibility of race conditions. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the bug which causes RSS to continue to work after being disabled. After disabling RSS, traffic would continue to be assigned to different queues instead of falling back to a single queue. Without this patch, attempting to disable RSS would not work as expected. This patch fixes the bug by clearing the lookup table used by RSS such that all traffic is assigned to a single queue. This patch also addresses the issue of reinstating the lookup table should RSS then be re-enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a driver is unable to maintain all current user supplied settings from ethtool (or other sources), it is not ok for a user request to succeed and silently trample over previous configuration. To that end, if you change the number of channels, it must not be allowed to reduce the number of channels (queues) below the current flow director filter rules targets. In this case, return -EINVAL when a request to reduce the number of channels would do so. In addition log a warning to the kernel buffer explaining why we failed, and report the rules which prevent us from lowering the number of channels.

* net_sched: convert tcf_exts from list to pointer arrayWANG Cong2016-08-17
| | | | | | | | | | | | | | | | | | | | | As pointed out by Jamal, an action could be shared by multiple filters, so we can't use list to chain them any more after we get rid of the original tc_action. Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

* i40e: check for and deal with non-contiguous TCsDave Ertman2016-08-16
| | | | | | | | | | | | | | | | | | | The i40e driver was causing a kernel panic when non-contiguous Traffic Classes, or Traffic Classes not starting with TC0, were configured on a link partner switch. i40e does not support non-contiguous TCs. To fix this, the patch changes the logic when determining the total number of TCs enabled. Before, this would use the highest TC number enabled and assume that all TCs below it were also enabled. Now, we create a bitmask of enabled TCs and scan it to determine not only the number of TCs, but also if the set of enabled TCs starts at zero and is contiguous. If not, then DCB is disabled by only returning one TC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix PHY delay compensation math in igb_ptp_tx_hwtstamp() and igb_ptp_rx_rgtstamp. Add PHY delay compensation in igb_ptp_rx_pktstamp().

The previous commit only changed igb_ptp_rx_rgtstamp(), and the change was incorrect. There are two instances in which PHY delay compensations should be made: - Before the packet transmission over the PHY, the latency between when the packet is timestamped and transmission of the packets, should be an add operation, but it is currently a subtract. - After the packets are received from the PHY, the latency between the receiving and timestamping of the packets should be a subtract operation, but it is currently an add.

Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where the index is not equal to zero. Fixes an issue where mac->ops.setup_fc can be NULL for backplanes which can cause the driver to crash on load. Don fixes the second parameter of the LED functions, which is the index to the LED we are interested in affecting. Fixed variable to store register reads to unsigned integer. Adds support for the new x553 hardware into ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked(). Fixed an issue where in ixgbevf_reset_subtask() was not verifying that the port has been removed. Cleans up the initial crosstalk fix, since the SFP that indicates the presence of a SFP+ module changes between hardware types. Babu Moger fixes typo in freeing IRQ, since the array subscript increments after the execution of the statement. Wei Yongjun adds the missing destroy_workqueue() before returning from ixgbe_init_module() in the error handling case. Tony adds range checking for setting the MTU from the VF, where the PF can return a NACK but this was not passed on to the VF, so propagate the results from the PF to the VF so errors can be reported. Consolidates mailbox read and write functions, since the recent changes to ixgbevf_write_msg_read_ack(), other functions are performing the same operations done here. Colin Ian King removes a redundant check on ret_val, since ret_val has not changed since the previous check. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch address a few issues with the initial crosstalk fix. Most important of which is the SDP that indicates the presents of a SFP+ module changes between HW types. With this change that is taken in to consideration It also moves the check closer to the base code that checks link. This makes it so we only need to do the check in one spot.
