Let caller know the result of adding/removing vlan id to/from vlan filter. In some drivers I make those functions to just return 0.

2011-12-08net/fec: fix the .remove codeLothar Waßmann
The .remove code is broken in several ways. - mdiobus_unregister() is called twice for the same object in case of dual FEC - phy_disconnect() is being called when the PHY is already disconnected - the requested IRQ(s) are not freed - fec_stop() is being called with the inteface already stopped All of those lead to kernel crashes if the remove function is actually used.

2011-12-05r8169: fix Rx index race between FIFO overflow recovery and NAPI handler.françois romieu
Since 92fc43b4159b518f5baae57301f26d770b0834c9, rtl8169_tx_timeout ends up resetting Rx and Tx indexes and thus racing with the NAPI handler via -> rtl8169_hw_reset -> rtl_hw_reset -> rtl8169_init_ring_indexes What about returning to the original state ? rtl_hw_reset is only used by rtl8169_hw_reset and rtl8169_init_one. The latter does not need rtl8169_init_ring_indexes because the indexes still contain their original values from the newly allocated network device private data area (i.e. 0). rtl8169_hw_reset is used by: 1. rtl8169_down Helper for rtl8169_close. rtl8169_open explicitely inits the indexes anyway. 2. rtl8169_pcierr_interrupt Indexes are set by rtl8169_reinit_task. 3. rtl8169_interrupt rtl8169_hw_reset is needed when the device goes down. See 1. 4. rtl_shutdown System shutdown handler. Indexes are irrelevant. 5. rtl8169_reset_task Indexes must be set before rtl_hw_start is called. 6. rtl8169_tx_timeout Indexes should not be set. This is the job of rtl8169_reset_task anyway. The removal of rtl8169_hw_reset in rtl8169_tx_timeout and its move in rtl8169_reset_task do not change the analysis.

2011-12-05r8169: Rx FIFO overflow fixes.françois romieu
Realtek has specified that the post 8168c gigabit chips and the post 8105e fast ethernet chips recover automatically from a Rx FIFO overflow. The driver does not need to clear the RxFIFOOver bit of IntrStatus and it should rather avoid messing it. The implementation deserves some explanation: 1. events outside of the intr_event bit mask are now ignored. It enforces a no-processing policy for the events that either should not be there or should be ignored. 2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the whole 8168 line of chips with two exceptions: - RTL_GIGA_MAC_VER_22 since b5ba6d12bdac21bc0620a5089e0f24e362645efd ("use RxFIFO overflow workaround for 8168c chipset."). This one should now be correctly handled. - RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO overflow processing. Though it does not conform to Realtek suggestion above, the updated driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17. Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather wait for experimental evidence that the change suggested by Realtek really helps or does not hurt in unexpected ways. Removed case statements in rtl8169_interrupt are only 8168 relevant. 3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e (RTL_GIGA_MAC_VER_30) itself.

2011-12-05ixgbe: DCB: IEEE transitions may fail to reprogram hardware.John Fastabend
Transitioning through an IEEE DCBX version from a CEE DCBX and back (CEE->IEEE->CEE) may leave IEEE attributes programmed in the hardware. DCB uses a bit field in the set routines to determine which attributes PG, PFC, APP need to be reprogrammed. This is needed because user flow allows queueing a series of changes and then reprogramming the hardware with the entire set in one operation. When transitioning from IEEE DCBX mode back into CEE DCBX mode the PG and PFC bits need to be set so the possibly different CEE attributes get programmed into the device. This patch fixes broken logic that was evaluating to 0 and never setting any bits. Further this removes some checks for num_tc in set routines. This logic only worked when the number of traffic classes and user priorities were equal. This is no longer the case for X540 devices. Besides we can trust user input in this case if the device is incorrectly configured the DCB bandwidths will be incorrectly mapped but no OOPs, BUG, or hardware failure will occur.

2011-12-05ixgbe: DCBnl set_all, order of operations fixJohn Fastabend
The order of operations is important in DCBnl set_all(). When FCoE is configured it uses the up2tc map to learn which queues to configure the hardware offloads on. Therefore we need to setup the map before configuring FCoE. This is only seen when the both up2tc mappings and APP info are configured simultaneously.

2011-12-05e1000e: hitting BUG_ON() from napi_enableBruce Allan
Based on a patch from Mike McElroy created against the out-of-tree e1000e driver: Hitting the BUG_ON in napi_enable(). Code inspection shows that this can only be triggered by calling napi_enable() twice without an intervening napi_disable(). I saw the following sequence of events in the stack trace: 1) We simulated a cable pull using an Extreme switch. 2) e1000_tx_timeout() was entered. 3) e1000_reset_task() was called. Saw the message from e_err() in the console log. 4) e1000_reinit_locked was called. This function calls e1000_down() and e1000_up(). These functions call napi_disable() and napi_enable() respectively. 5) Then on another thread, a monitor task saw carrier was down and executed 'ip set link down' and 'ip set link up' commands. 6) Saw the '_E1000_RESETTING'warning fron the e1000_close function. 7) Either the e1000_open() executed between the e1000_down() and e1000_up() calls in step 4 or the e1000_open() call executed after the e1000_up() call. In either case, napi_enable() is called twice which triggers the BUG_ON.
