2011-12-05ixgbe: DCB: IEEE transitions may fail to reprogram hardware.John Fastabend1-11/+10
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 Fastabend1-48/+29
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 Allan1-2/+2
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.

2011-11-29tg3: Scale back code that modifies MRRSMatt Carlson1-17/+10
Tg3 normally gets a performance boost by increasing the PCI Maximum Read Request Size (MRRS) to 4k. Unfortunately, this is causing some problems on particular hardware platforms. This patch removes all code that modifies the MRRS except for one case. As part of a solution to fix an internal FIFO problem on the 5719, the driver artificially capped the MRRS to 2k for the entire 5719, and later 5720, ASIC revs. This was overly aggressive and only really needed to be done for the 5719 A0. In the spirit of the rest of this patch, the driver will only reprogram the MRRS for this device if the value exceeds the 2k cap.

2011-11-29tg3: Fix TSO CAP for 5704 devs w / ASF enabledMatt Carlson1-2/+12
On the earliest TSO capable devices, TSO was accomplished through firmware. The TSO cannot coexist with ASF management firmware though. The tg3 driver determines whether or not ASF is enabled by calling tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory. Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled "tg3: Move TSO_CAPABLE assignment", accidentally moved the code that determines TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a consequence, the driver was attempting to determine TSO capabilities before it had all the data it needed to make the decision. This patch fixes the problem by revisiting and reevaluating the decision after tg3_get_eeprom_hw_cfg() is called.
