Jake updates the ethtool statistics to use a helper function since many of the statistics use the same basic logic for copying strings into the supplied buffer. Cleaned up the use of a local variable that is no longer needed or used. Fixed additional stats issues, including the failure to update the data pointer which was causing stats to be reported incorrectly. Mariusz fixes a bug where there was an oversight in configuring FEC when link settings were forced which was causing 25G link to be configured incorrectly. Piotr adds a missing return code for when the firmware returns a busy state. Also added the process to command firmware to start rearrangement when switching between old NVM structure to the new flat NVM. ==================== Signed-off-by: David S.

2018-08-07qed: Add Multi-TC RoCE supportDenis Bolotin3-32/+121
RoCE qps use a pair of physical queues (pq) received from the Queue Manager (QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block creates a pq for each TC, and allows RoCE qps to ask for a pq with a specific TC. As a result, qps with different VLAN priorities can be mapped to different TCs, and employ features such as PFC and ETS.

2018-08-07i40e: fix i40e_add_queue_stats data pointer updateJacob Keller1-1/+6
This function accidentally failed to update the data pointer, which caused the reported stats to be incorrect. Additionally, statistics which follow queue stats in the output would potentially read non-zeroed garbage data from the ethtool buffer. This occurred because the data double pointer was not dereferenced before incrementing the size. Additionally, make sure this issue is more visible by adding a WARN_ONCE to the i40e_get_ethtool_stats function. This warning will trigger whenever the data pointer is not at the expected address, similar to the check that we make in the i40e_get_stat_strings() function.

2018-08-07i40e: fix warning about shadowed ring parameterJacob Keller1-4/+2
In commit 147e81ec7568 ("i40e: Test memory before ethtool alloc succeeds") code was added to handle ring allocation on systems with low memory. It shadowed the ring parameter pointer by introducing a local ring pointer inside the for loop. Most of the code in the loop already just accessed the ring via &rx_rings[i]. Since most of the code already does this, just remove the local variable. If someone considers it worth keeping a local around, they should use it for the whole section instead of just a couple of accesses.

2018-08-07i40e: convert priority flow control stats to use helpersJacob Keller1-36/+51
The priority flow control statistics are laid out in the stats structure using arrays. This made it unwieldy to use as part of an i40e_stats array. Add a new structure type, i40e_pfc_stats, and a helper function i40e_get_pfc_stats which can return the stats for a given priority value as an i40e_pfc_stats structure. Use this to create an i40e_stats array, which we'll use to format and copy the strings and stats into the supplied buffers. This reduces even more boiler plate code in i40e_get_ethtool_stats and i40e_get_stat_strings. An alternative would be to modify the structure definition for the pfc stats, but this is more invasive to the rest of the code base. Note that a macro was used to setup the copy of stats from the pf->stats, as this reduces the chance of typos in the code names. It will produce a checkpatch.pl warning due to re-use of a macro argument. In this case, it should be safe, as the macro will fail to compile in cases where the argument is not a simple structure member name, and thus arguments with side effects should not be an issue.

2018-08-07i40e: convert VEB TC stats to use an i40e_stats arrayJacob Keller1-40/+43
The VEB TC stats are currently implemented with separate parsing, instead of using the i40e_stats array and associated helper functions. This is likely because the stats rely on embedding the TC number into the stat name. Update i40e_add_stat_strings to take variadic arguments, and use these to vsnprintf the i40e_stats string as a string containing format specifiers. Create a stats array for the VEB TC related stats, i40e_gstrings_veb_tc_stats, and use this along with the helper functions to remove the specialized boiler plate code. Always call i40e_add_ethtool_stats for both this array and the general VEB stats array. This ensures that we zero out any memory in case it was not zero-allocated for us. This ultimately results in less boiler plate code for the i40e_get_stat_strings and i40e_get_ethtool_stats.

2018-08-07i40e: add helper function for copying strings from stat arraysJacob Keller1-20/+39
Many of the ethtool statistics use the same basic logic for copying strings into the supplied buffer. A set of stats are stored in a const array of i40e_stats structures, and we apply these all together. Simplify the stats code by introducing a helper function which can take a stats array and copy the strings into the buffer, updating the buffer pointer as we go. We use a macro to implement i40e_add_stat_strings so that ARRAY_SIZE can be used on the array passed in. This ensures that we always use the matching size in __i40e_add_stat_strings. More complex stats currently do not use i40e_stats arrays, usually due to custom formatted strings, or because the stats are not laid out in the expected way. These stats will be updated to use the helper function in separate future patches.

We use to have message like: struct vhost_msg { int type; union { struct vhost_iotlb_msg iotlb; __u8 padding[64]; }; }; Unfortunately, there will be a hole of 32bit in 64bit machine because of the alignment. This leads a different formats between 32bit API and 64bit API. What's more it will break 32bit program running on 64bit machine. So fixing this by introducing a new message type with an explicit 32bit reserved field after type like: struct vhost_msg_v2 { __u32 type; __u32 reserved; union { struct vhost_iotlb_msg iotlb; __u8 padding[64]; }; }; We will have a consistent ABI after switching to use this. To enable this capability, introduce a new ioctl (VHOST_SET_BAKCEND_FEATURE) for userspace to enable this feature (VHOST_BACKEND_F_IOTLB_V2).

2018-08-06mellanox: fix the dport endianness in call of __inet6_lookup_established()Al Viro1-1/+1
__inet6_lookup_established() expect th->dport passed in host-endian, not net-endian. The reason is microoptimization in __inet6_lookup(), but if you use the lower-level helpers, you have to play by their rules...

2018-08-06ieee802154: fakelb: add deprecated msg while probeAlexander Aring1-0/+3
Since mac802154_hwsim the fakelb driver will get deprecated. This patch will notifier all users of fakelb to switch to the new mac802154_hwsim driver. Signed-off-by: Alexander Aring <aring@mojatatu.com> Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org>
2018-08-06ieee802154: hwsim: add replacement for fakelbAlexander Aring4-0/+1004
This patch adds a new virtual driver mac802154_hwsim which is based on the fakelb driver. The fakelb driver will get deprecated and hopefully removed someday. The main reason for doing this step is to rename the driver to mac802154_hwsim to have a similar naming scheme as mac80211_hwsim, which is more popular in the 802.11 wireless word and the idea is the same behind this driver. The new features of this driver are to have knowledge about connected edges, which can be changed during runtime. This offers a testing environment for routing protocols e.g. RPL. The default behaviour is still as fakelb: two radios connected to each other. New added radios during runtime will not be connected to other wpan_hwsim instances. The netlink api is not namespace aware on purpose, only the registered wpan_phy's can be moved to namespaces. The physical layer according to wiresless "air" communication can be handled across namespaces. Furthermore the edges can be weighted with the LQI value according IEEE 802.15.4 which offers additional handling to mark bad or good connection indicators to other connected virtual phys.

Also iwlwifi got support for the new IEEE 802.11ax standard, the successor for 802.11ac. And naturally smaller new features and bugfixes all over. Major changes: wcn36xx * fix WEP in client mode wil6210 * add support for Talyn-MB (Talyn ver 2.0) device * add support for enhanced DMA firmware feature iwlwifi * implement 802.11ax D2.0 * support for the new 22560 device family * new PCI IDs for 22000 and 22560 qtnfmac * implement cfg80211 power management callback * enable multiple SSIDs scan support * qtnfmac: implement basic WoWLAN support mt7601u * fall back to software encryption for hw unsupported ciphers * enable 802.11 Management Frame Protection (MFP) mt76 * support setting RTS threshold * add USB support * add support for MT76x2u devices * add support for MT76x0U devices mwifiex * allow user space to set all other IEs except WMM IE rsi * add firmware support for AP+BT dual mode ==================== Signed-off-by: David S.
