2015-03-31ptp: bnx2x: convert to the 64 bit get/set time methods.Richard Cochran
This driver's clock is implemented using a timecounter, and so with this patch the driver is ready for the year 2038. Compile tested only. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Acked-by: Sony Chacko <sony.chacko@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-29net: Move check for multiple vlans to driversToshiaki Makita
To allow drivers to handle the features check for multiple tags, move the check to ndo_features_check(). As no drivers currently handle multiple tagged TSO, introduce dflt_features_check() and call it if the driver does not have ndo_features_check().

2015-03-23bnx2x: Fix statistics locking schemeYuval Mintz
Statistics' state-machine in bnx2x driver must be synced with various driver flows, but its current locking scheme manages to be wasteful [using 2 locks + additional local variable] and prone to race-conditions at the same time, as the state-machine and 'action' are being accessed under different locks. In addition, current 'safe exec' isn't in fact safe, since the only guarantee it gives is that DMA transactions are over, but ramrods might still be running. This patch cleans up said logic, leaving us with a single lock for the entire flow and removing the possible races. Changes from v2: - Switched into mutex locking from semaphore locking. - Release locks on error flows. Changes from v1: Failure to acquire lock fails flow instead of printing a warning and allowing access to the critical section.

Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-16bnx2x: fix encapsulation features on 57710/57711Michal Schmidt
E1x chips (57710, 57711(E)) have no support for encapsulation offload. bnx2x incorrectly advertises the support as available. Setting of those features is conditional on "!CHIP_IS_E1x(bp)", but the bp struct is not initialized yet at this point and consequently any chip passes the check. The check must use the "chip_is_e1x" local variable instead to work correctly. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-12-26net: Generalize ndo_gso_check to ndo_features_checkJesse Gross
GSO isn't the only offload feature with restrictions that potentially can't be expressed with the current features mechanism. Checksum is another although it's a general issue that could in theory apply to anything. Even if it may be possible to implement these restrictions in other ways, it can result in duplicate code or inefficient per-packet behavior. This generalizes ndo_gso_check so that drivers can remove any features that don't make sense for a given packet, similar to netif_skb_features(). It also converts existing driver restrictions to the new format, completing the work that was done to support tunnel protocols since the issues apply to checksums as well. By actually removing features from the set that are used to do offloading, it solves another problem with the existing interface. In these cases, GSO would run with the original set of features and not do anything because it appears that segmentation is not required.

2014-12-09bnx2x: Use correct fastpath version for VFs.Yuval Mintz
Our FW can support several fastpath HSI [for backward compatibility] but up until now VFs were always configured to use latest fastpath HSI [although VF driver might be older and use an older fastpath HSI]. For linux drivers, the differences are insignificant since driver never utilized features that were overridden by the HSI change. But for VMs running other operating systems this might be a problem. In addition, eventually FW might change fastpath HSI in such a manner that backward compatibility WILL break unless configured with proper version. This patch fixes the issue for other operating system VMs, as well as lays the ground work for forward compatibility in regard to the fastpath HSI.

2014-09-02bnx2x: Configure device endianity on driver load and reset endianity on removal.Manish Chopra
Some hosts can be both little and big endian. In certain scenarios a big endian kernel can kexec a little endian kernel.

2014-08-21bnx2x: Revert UNDI flushing mechanismYuval Mintz
Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.

2014-03-25bnx2x: Create workqueue for IOV related tasksYuval Mintz
The bnx2x sriov mechanisms were done in the bnx2x slowpath workitem which runs on the bnx2x's workqueue; This workitem is also responsible for the bottom half of interrupt handling in the driver, and specifically it also receives FW notifications of ramrod completions, allowing other flows to progress. The original design of the sriov reltaed-flows was based on the notion such flows must not sleep, since their context is the slowpath workitem. Otherwise, we might reach timeouts - those flows may wait for ramrod completion that will never arrive as the workitem wlll not be re-scheduled until that same flow will be over. In more recent time bnx2x started supporting features in which the VF interface can be configured by the tools accessing the PF on the hypervisor. This support created possible races on the VF-PF lock (which is taken either when the PF is handling a VF message or when the PF is doing some slowpath work on behalf of the VF) which may cause timeouts on the VF side and lags on the PF side. This patch changes the scheme - it creates a new workqueue for sriov related tasks and moves all handling currently done in the slowpath task into the the new workqueue.

This adds support in a new management feature which needs the driver versions (bnx2x, bnx2fc and bnx2i) loaded for each interface. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: Ariel Elior <Ariel.Elior@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-02-26bnx2x: save RAM in kdump kernel by disabling TPAMichal Schmidt
When running in a kdump kernel, disable TPA. This saves memory, which tends to be scarce in kdump. TPA, being a receive acceleration, is unlikely to be useful for kdump, whose purpose is to send the memory image out. This saves additional 5 MB in the kdump environment.
