* net: sched: Pass qdisc reference in struct flow_block_offloadPetr Machata2020-07-139-32/+38
| | | | | | | | | | | | | | | | | Previously, shared blocks were only relevant for the pseudo-qdiscs ingress and clsact. Recently, a qevent facility was introduced, which allows to bind blocks to well-defined slots of a qdisc instance. RED in particular got two qevents: early_drop and mark. Drivers that wish to offload these blocks will be sent the usual notification, and need to know which qdisc it is related to. To that end, extend flow_block_offload with a "sch" pointer, and initialize as appropriate. This prompts changes in the indirect block facility, which now tracks the scheduler in addition to the netdevice. Update signatures of several functions similarly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit affects comments (and in one case, whitespace) only. Throughout the IPA code, return statements are documented using "@Return:", whereas they should use "Return:" instead. Fix these mistakes. In function definitions, some parameters are missing their comment to describe them. And in structure definitions, some fields are missing their comment to describe them. Add these missing descriptions. Some arguments changed name and type along the way, but their descriptions were not updated (an endpoint pointer is now used in many places that previously used an endpoint ID). Fix these incorrect parameter descriptions. In the description for the ipa_clock structure, one field had a semicolon instead of a colon in its description. Fix this. Add a missing function description for ipa_gsi_endpoint_data_empty(). All of these issues were identified when building with "W=1".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The FEC allocates 2K buffers, but looses some of it due to alignment. It can however support an MTU bigger than the default. This is particularly interesting when used in combination with Ethernet switches supporting DSA, which have extra headers. The DSA core will try to increase the MTU to support these extra headers. If the max size defaults to that of standard Ethernet we get a warning. By setting the max to what the driver actually supports, we avoid this warning.

* net: bridge: notify on vlan tunnel changes done via the old apiNikolay Aleksandrov2020-07-121-2/+47
| | | | | | | | | | | | | | | | | | | | | If someone uses the old vlan API to configure tunnel mappings we'll only generate the old-style full port notification. That would be a problem if we are monitoring the new vlan notifications for changes. The patch resolves the issue by adding vlan notifications to the old tunnel netlink code. As usual we try to compress the notifications for as many vlans in a range as possible, thus a vlan tunnel change is considered able to enter the "current" vlan notification range if: 1. vlan exists 2. it has actually changed (curr_change == true) 3. it passes all standard vlan notification range checks done by br_vlan_can_enter_range() such as option equality, id continuity etc Note that vlan tunnel changes (add/del) are considered a part of vlan options so only RTM_NEWVLAN notification is generated with the relevant information inside.

This happens because as part of the reload error path the PCI command interface is de-initialized and its mailboxes are freed. When the devlink '->info_get()' callback is invoked the device is queried via the command interface and the freed mailboxes are accessed. Fix this by initializing the command interface once during probe and not during every reload. This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c') and also allows user space to query the running firmware version (for example) from the device after a failed reload.
