* | e1000e: use default settings for Tx Inter Packet Gap timerBruce Allan2012-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the default hardware values for TIPG except for 80003es2lan(*). The code that is removed in this patch is either unnecessarily writing the TIPG register with the hardware default values for some devices (82571/2/3/4) or writing the wrong value for others (ICH/PCH LOMs). The only change in functionality is setting the correct default TIPG for the latter devices. (*) The correct value for 80003es2lan is already set properly in e1000_init_hw_80003es2lan() and e1000_cfg_kmrn_{10_100|1000}_80003es2lan(), and the unused flag FLAG_TIPG_MEDIUM_FOR_80003ESLAN is removed.

Disallow jumbo frames when both receive checksum and receive hashing are enabled because the hardware cannot do both IP payload checksum (enabled when receive checksum is enabled when using packet split which is used for jumbo frames) and provide RSS hash at the same time. v2: added ethtool command to query flow hashing behavior per Ben Hutchings and changed the type of rsskey to cleanup the setting of the register array and avoid unnecessary casts (as pointed out by Joe Perches). The long error messages are not changed since there is nothing in the kernel ./Documentation that suggests the preferred method for dealing with long messages other than to never break strings; leaving them as-is for now.

* e1000: fix lockdep splat in shutdown handlerJesse Brandeburg2012-01-05
| | | | | | | | | | | | | | | | | | | | | | | As reported by Steven Rostedt, e1000 has a lockdep splat added during the recent merge window. The issue is that cancel_delayed_work is called while holding our private mutex. There is no reason that I can see to hold the mutex during pci shutdown, it was more just paranoia that I put the mutex_lock around the call to e1000_down. In a quick survey lots of drivers handle locking differently when being called by the pci layer. The assumption here is that we don't need the mutexes' protection in this function because the driver could not be unloaded while in the shutdown handler which is only called at reboot or poweroff.

* ixgbe: DCB: IEEE transitions may fail to reprogram hardware.John Fastabend2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* e1000e: hitting BUG_ON() from napi_enableBruce Allan2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
