2016-07-22i40e: refactor Rx filter handlingMitch Williams3-279/+261
Properly track filter adds and deletes so the driver doesn't lose filters during resets and up/down cycles. Add a tracking mechanism so that the driver knows when to enter and leave promiscuous mode. Implement a simple state machine so the driver can track the status of each filter throughout its lifecycle. Properly manage the overflow promiscuous state for the each VSI, and provide a way for the driver to detect when to exit overflow promiscuous mode. Remove all possible default MAC filters that the firmware may have set up so that the driver can manage these correctly, particularly when VLANs come into play. Remove the LAA flag for filters; instead just send whatever we get through set_mac to the firmware as the LAA for wakeup purposes. Finally, add the state of each filter to debugfs output so we can see what's going on inside the driver's pointy little head.

Ngai-Mint provides a fix to clear PCIE_GMBX bits to ensure the proper functioning of the mailbox global interrupt after a data path reset. Jake provides most of the patches in the series, starting with a early return from fm10k_down() if we are already down to prevent conflict with other threads. Fixed an issue where fm10k_update_stats() could cause a null pointer dereference, specifically if it is called when we are going down and the rings have been removed. Cleans up and fixes the data path reset flow, Tx hang routine and stop_hw(). Re-worked the fm10k_reinit() to be more maintainable and fixed several inconsistencies with the work flow. Implemented fm10k_prepare_suspend() and fm10k_handle_resume() which abstract around the now existing fm10k_prepare_for_reset and fm10k_handle_reset. The new functions also handle stopping the service task, which is something that the original re-init flow does not need. Fixed an issue where if an FLR occurs, VF devices will be knocked out of bus master mode, and the driver will be unable to recover from the reset properly, so ensure bus master is enabled after every reset. Fixed an issue where a reset will occur as if for no reason, regularly every few minutes until the switch manager software is loaded, which is caused by continuously requesting the lport map so only do the request after we have verified the switch mailbox is tx_ready. ==================== Signed-off-by: David S.

The 6352 family of switches and compatibles provide a 8-bit address and 16-bit data access to an optional EEPROM. Newer chip such as the 6390 family slightly changed the access to 16-bit address and 8-bit data. This commit cleans up the EEPROM access code for 16-bit access and makes it easy to eventually introduce future support for 8-bit access. Here's a list of notable changes brought by this patch: - provide Global2 unlocked helpers for EEPROM commands - remove eeprom_mutex, only reg_lock is necessary for driver functions - eeprom_len is 0 for chip without EEPROM, so return it directly - the Running bit must be 0 before r/w, so wait for Busy *and* Running - remove now unused mv88e6xxx_wait and mv88e6xxx_reg_write - other than that, the logic (in _{get,set}_eeprom16) didn't change Chips with an 8-bit EEPROM access will require to implement the 8-suffixed variant of G2 helpers and the related flag: #define MV88E6XXX_FLAGS_EEPROM8 \ (MV88E6XXX_FLAG_G2_EEPROM_CMD | \ MV88E6XXX_FLAG_G2_EEPROM_ADDR) Signed-off-by: Vivien Didelot <[email protected]> Reviewed-by: Andrew Lunn <[email protected]> Signed-off-by: David S.

2016-07-20fm10k: implement request_lport_map pointerJacob Keller3-13/+9
If the fm10k interface is brought up, but the switch manager software is not running, the driver will continuously request the lport map every few seconds in the base driver watchdog routine. Eventually after several minutes the switch mailbox Tx fifo will fill up and the mailbox will timeout, resulting in a reset. This reset will appear as if for no reason, and occurs regularly every few minutes until the switch manager software is loaded. Prevent this from happening by only requesting the lport map after we've verified the switch mailbox is tx_ready. In order to simplify code logic and reduce code duplication, implement this as a new function pointer "mac.ops.request_lport_map" which the VF will not implement. Otherwise, we have to duplicate the tx_ready check outside of fm10k_get_host_state_generic, or re-implement most of fm10k_get_host_state_generic in the pf version. The resulting code is simpler and easier to understand, and prevents the PF from continuously requesting lport map and filling the Tx fifo of a switch mailbox that isn't ready.
