And most of them are completely and utterly wrong. That's definitely the case when you write a specialty driver for a very unsual "security processor". It does *not* get to mark itself as "default m". If you solve world hunger, and make a driver that cures people of cancer, by all means enable it by default. But afaik, the Cavium CNN55XX does neither.

However, flushing the work queue may do more work than needed, and in particular, it may call into DLM, which we want to avoid here. Use a bit lock (GIF_GLOP_PENDING) to synchronize between the inode glops and gfs2_evict_inode instead to get rid of the flushing. In addition, flush the work queues of existing glocks before reusing them for new inodes to get those glocks into a known state: the glock state engine currently doesn't handle glock re-appropriation correctly. (We may be able to fix the glock state engine instead later.) Based on a patch by Steven Whitehouse <[email protected]>.

There are some boards which have the pin strapped this way and need software workaround suggested by the data manual. Bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0.

It further advises that if a board has this pin strapped in mode 1 and mode 2, then to ensure proper operation of the PHY, a software workaround must be implemented. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property for the board to advertise this and allow corrective action in software.

There are cases, however, where the old format is preferred - mostly to make interoperation with VFs using ABI 3.x easier for the datapath. In ABI 5.x we allowed for more flexibility by selecting the metadata format based on capabilities. The default was left to non-chained. In case of fallback traffic, there is no capability telling the driver there may be chained metadata. With a very stripped- -down FW the default old metadata format would be selected making the driver drop all fallback traffic. This patch changes the default selection in the driver. It should not hurt with old firmwares, because if they don't advertise RSS they will not produce metadata anyway. New firmwares advertising ABI 5.x, however, can depend on the driver defaulting to chained format.

We are probably better off picking random addresses than the wrong ones in the theoretical scenario where management FW didn't tell us what the port config is.

This means that if user configures breakout on a multiport card, the first interface of the second port will have its MAC address changed. What's worse, when moved from static information (HWInfo) to using management FW (NSP), more features started depending on the port ids. Right now in case of breakout first subport of the second port and second subport of the first port will have their link info swapped. Revise the ordering scheme so that first subport maintains its address. Side effect of this change is that we will use base lane ids in devlink (i.e. 40G ports will be 4 ids apart), e.g.: pci/0000:04:00.0/0: type eth netdev p6p1 pci/0000:04:00.0/4: type eth netdev p6p2 Note that behaviour of phys_port_id is not changed since there is a separate id number for the subport there.
