2018-01-12net: hns3: add int_gl_idx setup for TX and RX queuesFuyun Liang3-0/+21
If the int_gl_idx does not be set, the default interrupt coalesce index is 0. The TX queues and the RX queues will both use the GL0 as the interrupt coalesce GL switch. But it should be GL1 for TX queues and GL0 for RX queues. This patch adds the int_gl_idx setup for TX queues and RX queues.

2018-01-12net: hns3: change the unit of GL value macroFuyun Liang1-4/+4
Previously, driver used 2us as the GL unit. The time unit ethtool command "-c" and "-C" use is 1us, so now the GL unit driver uses actually is 1us.

2018-01-12net: hns3: refactor GL update functionFuyun Liang1-18/+15
The GL update function uses the max GL value between tx_int_gl and rx_int_gl to set both new tx_int_gl and new rx_int_gl. Therefore, User can not enable TX GL self-adaptive or RX GL self-adaptive individually. This patch refactors the code to update the TX GL and the RX GL separately, making user can enable TX GL self-adaptive or RX GL self-adaptive individually.

2018-01-12net: hns3: refactor interrupt coalescing init functionFuyun Liang1-9/+20
In the hardware, the coalesce configurable registers include GL0, GL1, GL2. In the driver, the TX queues use the register GL1 and the RX queues use the register GL0. This function initializes the configuration of the interrupt coalescing, but does not distinguish between the TX direction and the RX direction. It will cause some confusion. This patch refactors the function to initialize the TX GL and the RX GL separately. And the initialization of related variables also is added to this patch.

BPF alignment tests got a conflict because the registers are output as Rn_w instead of just Rn in net-next, and in net a fixup for a testcase prohibits logical operations on pointers before using them. Also, we should attempt to patch BPF call args if JIT always on is enabled. Instead, if we fail to JIT the subprogs we should pass an error back up and fail immediately. Signed-off-by: David S.

Set features function sets dev->features in order to keep track of which features were successfully changed and which weren't (in case the user asks for more than one change in a single command). This breaks the logic in __netdev_update_features which assumes that dev->features is not changed on success and checks for diffs between features and dev->features (diffs that might not exist at this point because of the driver override). The solution is to keep track of successful/failed feature changes and assign them to dev->features in case of failure only.

There are systems platform information management interfaces (such as HOST2BMC) for which we cannot disable local loopback multicast traffic. Separate disable_local_lb_mc and disable_local_lb_uc capability bits so driver will not disable multicast loopback traffic if not supported. (It is expected that Firmware will not set disable_local_lb_mc if HOST2BMC is running for example.)

Alice adds the displaying of priority xon/xoff packet stats, since we were already keeping track of them. Based on the recent changes, bump the driver versions. Jake changes how the driver determines whether or not the device is currently up to resolve the possible issue of freeing data structures and other memory before they have been fully allocated. Refactored the driver to simplify the locking behavior and to consistently use spinlocks instead of an overloaded bit lock to protect MAC and filter lists. Created a helper function which can convert the AdminQ link speed definition into a virtchnl definition. Colin Ian King cleans up a redundant variable initialization. Alex cleans up the driver to stop clearing the pending bit array for each vector manually, since it is prone to dropping an interrupt and based on the hardware specs, the pending bit array will be cleared automatically in MSI-X mode. Cleaned up flags for promiscuous mode to resolve an issue where enabling & disabling promiscuous mode on a VF would leave us in a high polling rate for the adminq task. Cleaned up code that was prone to race issues. Jingjing renames pipeline personalization profile (ppp) to dynamic device personalization (ddp) because it was being confused with the well known point to point protocol. Also removed checks for "track_id" being zero, since it is valid for it to be zero for profiles that do not have any 'write' commands. v2: cleaned up commit message for patch 12 based on feedback from Sergei Shtylyov and Alex Duyck v3: dropped patch 15 from the original series while Mariusz Stachura works on the changes that Jakub Kicinski has suggested ==================== Signed-off-by: David S.

However, quite a significant amount of existing code wants to manipulate the masks directly, and thus now uses the first unsigned long (i.e. mask[0]) as though it were a legacy u32 mask.

Each one of them, beside replace, checks if the handle doesn't match the qdisc in the given location, and if so, it returns without running the actual op. Unite these checks to one comparison function and avoid sending the handle id to these ops.

2018-01-10mlxsw: spectrum: qdiscs: Add tclass number to the mlxsw_sp_qdiscNogah Frankel1-18/+18
Tclass number is needed for most of the operations related to the qdisc in the driver. Create a field for it in the mlxsw_sp_qdisc instead of passing it to every function as parameter.

2018-01-10mlxsw: spectrum: qdiscs: Make the clean stats function to be for RED onlyNogah Frankel1-19/+12
Improve readability by changing the clean stats function to handle only RED. Qdiscs that will be offloaded in the future will have a clean stats function of their own.

Clean RED offloaded stats and make them more generic by breaking the generic qdisc stats to a struct of their own.

2018-01-10net: sch: red: Change offloaded xstats to be incrementalNogah Frankel1-3/+12
Change the value of the xstats requested from the driver for offloaded RED to be incremental, like the normal stats. It increases consistency - if a qdisc stops being offloaded its xstats don't change.

Change the name of the stats struct to be generic, so it could be used for other qdisc offload, that will be added in the next patches.
