* ixgbe: Pass staterr instead of re-reading status and error bits from descriptorAlexander Duyck2011-07-221-29/+6
| | | | | | | | | | | This change is meant to address possible race conditions from the status and error bits on the RX descriptors being re-read by multiple functions in the RX cleanup path. To resolve this I have added code that will pass the staterr value to those functions.

* ixgbe: Add one function that handles most of context descriptor setupAlexander Duyck2011-06-251-54/+31
| | | | | | | | | | | There is a significant amount of shared functionality between the checksum and TSO offload configuration that is shared in regards to how they setup the context descriptors. Since so much of the functionality is shared it makes sense to move the shared functionality into a single function and just call that function from the two context descriptor specific routines.

* ixgbe: setup per CPU PCI pool for FCoE DDPVasu Dev2011-06-211-30/+75
| | | | | | | | | | | | | | | | | | Currently single PCI pool used across all CPUs and that doesn't scales up as number of CPU increases, so this patch adds per CPU PCI pool to setup udl and that aligns well from FCoE stack as that already has per CPU exch locking. Adds per CPU PCI alloc setup and free in ixgbe_fcoe_ddp_pools_alloc and ixgbe_fcoe_ddp_pools_free, use CPU specific pool during DDP setup.

* ixgbe: do not clear FCoE DDP error status for received ABTSYi Zou2011-04-271-2/+2
| | | | | | | | | | | | | The ddp->err is initialized to be 1 to make sure outstanding DDP context is guaranteed to be invalidated when HW is not auto-invalidating it. However, in case of receiving ABTS response for a DDPed I/O, the ddp->err was cleared, bypassing the invalidating of the DDP context from upper protocol stack when ixgbe_fcoe_ddp_put() is called. This bug is fixed here by updating the error only when FCP_RSP is received.

| | | | | | | | | | | | | | | The FCoE offload is enabled/disabled per adapter, but upper FCoE protocol stack could have multiple FCoE instances created on the same physical network interface, e.g., FCoE on multiple VLAN interfaces on the same physical network interface. In this case we want to turn on FCoE offload at the first request from ndo_fcoe_enable() but only turn off FCoE offload at the very last call to ndo_fcoe_disable(). This is fixed by adding a refcnt in the per adapter FCoE structure and tear down FCoE offload when refcnt decrements to zero.

* ixgbe: properly toggling netdev feature flags when disabling FCoEYi Zou2010-07-201-13/+6
| | | | | | | | | | | | | | | | | | | | When FCoE is disabled, there is a race condition that FCoE offload is turned off but the FCoE protocol driver is still queuing I/O thinking offload support still exists. This patch toggles off corresponding FCoE netdev feature flags and notify the FCoE stack first, allowing FCoE protocol stack driver to update its flags upon NETDEV_FEAT_CHANGE so no I/O will be using offload. Also, indicate FCoE offload flags in vlan_features in ixgbe_probe once and do not toggle them in ixgbe_fcoe_enable/disable so when FCoE is created on the VLAN interface, vlan_transfer_features() would properly update the VLAN netdev features flag and notify the FCoE protocol driver for NETDEV_FEAT_CHANGE.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* ixgbe: Add infrastructure code for FCoE large receive offload to 82599Yi Zou2009-05-171-0/+340
| | | | | | | | | | | | | | This adds infrastructure code for FCoE Rx side offload feature to 82599, which provides large receive offload for FCoE by Direct Data Placement (DDP). The ixgbe_fcoe_ddp_get() and ixgbe_fcoe_ddp_put() pair corresponds to the netdev support to FCoE by the function pointers provided in net_device_ops as ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done. The implementation of these in ixgbe is shown in the next patch.

* ixgbe: Add FCoE feature code to 82599Yi Zou2009-05-171-0/+60
This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599. In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add support of FCoE offload features to 82599.
