The igb and igc driver both use a trick of creating a local type pointer on the stack to ease dealing with a receive descriptor in 64 bit chunks for printing. Sparse however was not taken into account and receive descriptors are always in little endian order, so just make the unions use __le64 instead of u64. No functional change. Signed-off-by:

The error check and set_bit are placed in such a way that sparse (C=2) warns: .../fm10k_pci.c:1395:9: warning: context imbalance in 'fm10k_msix_mbx_pf' - different lock contexts for basic block Which seems a little odd, but the code can obviously be moved to where the variable is being set without changing functionality at all, and it even seems to make a bit more sense with the check closer to the set.

The sparse checker (C=2) found an assignment where we were mixing types when trying to convert from data read directly from the device NVM, to an array in CPU order in-memory, which unfortunately the driver tries to do in-place. This is easily solved by using the swap operation instead of an assignment, and is already proven in other Intel drivers to be functionally correct and the same code, just without a sparse warning. The change is the same in all three drivers. Signed-off-by:

Sparse tool was warning on some implicit conversions from little endian data read from the EEPROM on the e100 cards. Fix these by being explicit about the conversions using le16_to_cpu(). Signed-off-by:

Vladimir Oltean says: ==================== SJA1105 DSA driver preparation for new switch introduction (SJA1110) This series contains refactoring patches which are necessary before the support for the new NXP SJA1110 switch can be introduced in this driver. As far as this series is concerned, here is the list of major changes introduced with the SJA1110: - 11 ports vs 5 - port 0 goes to the internal microcontroller, so it is unused as far as DSA is concerned - the Clock Generation Unit does not need any configuration for setting up the PLLs for MII/RMII/RGMII - the L2 Policing Table contains multicast policers too, not just broadcast and per-traffic class. These must be minimally initialized. - more frame buffers ==================== Signed-off-by: -
Vladimir Oltean authored
The shared frame buffer of the SJA1110 is larger than that of SJA1105, which is natural due to the fact that there are more ports. Introduce yet another property in struct sja1105_info which encodes the maximum number of 128 byte blocks that can be used for frame buffers. Signed-off-by:

The SJA1110 policer array is similar in layout with SJA1105, except it contains one multicast policer per port at the end. Detect the presence of multicast policers based on the maximum number of supported L2 Policing Table entries, and make those policers have a shared index equal to the port's default policer. Letting the user configure these policers is not supported at the moment. Signed-off-by:

Vladimir Oltean authored
Due to the fact that the port count is different, some static config tables have a different number of elements in SJA1105 compared to SJA1110. Such an example is the L2 Policing table, which has 45 entries in SJA1105 (one per port x traffic class, and one broadcast policer per port) and 110 entries in SJA1110 (one per port x traffic class, one broadcast and one multicast policer per port). Similarly, the MAC Configuration Table, the L2 Forwarding table, all have a different number of elements simply because the port count is different, and although this can be accounted for by looking at ds->ports, the policing table can't because of the presence of the extra multicast policers. The common denominator for the static config initializers for these tables is that they must set up all the entries within that table. So the simplest way to account for these differences in a uniform manner is to look at struct sja1105_table_ops::max_entry_count. For the sake of uniformity, this patch makes that change also for tables whose number of elements did not change in SJA1110, like the xMII Mode Parameters, the L2 Lookup Parameters, General Parameters, AVB Parameters (all of these are singleton tables with a single entry).

There are two distinct code paths which enter sja1105_clocking.c, one through sja1105_clocking_setup() and the other through sja1105_clocking_setup_port(): sja1105_static_config_reload sja1105_setup | | | +------------------+ | | v v sja1105_clocking_setup sja1105_adjust_port_config | | v | sja1105_clocking_setup_port <------------------+ As opposed to SJA1105, the SJA1110 does not need any configuration of the Clock Generation Unit in order for xMII ports to work. Just RGMII internal delays need to be configured, and that is done inside sja1105_clocking_setup_port for the RGMII ports. So this patch introduces the concept of a "reserved address", which the CGU configuration functions from sja1105_clocking.c must check before proceeding to do anything. The SJA1110 will have reserved addresses for the CGU PLLs for MII/RMII/RGMII. Additionally, make sja1105_clocking_setup() a function pointer so it can be overridden by the SJA1110. Even though nothing port-related needs to be done in the CGU, there are some operations such as disabling the watchdog clock which are unique to the SJA1110. Signed-off-by: -

If @port is unused, then dsa_upstream_port(ds, port) returns @port, which means we cannot assume the CPU port can be retrieved this way. The sja1105 switches support a single CPU port, so just iterate over the switch ports and stop at the first CPU port we see. Signed-off-by:

Introduce a SJA1105_MAX_NUM_PORTS macro which at the moment is equal to SJA1105_NUM_PORTS (5). With the introduction of SJA1110, these structures will need to hold information for up to 11 ports. Signed-off-by:

Vladimir Oltean authored
The sja1105 driver will gain support for the next-gen SJA1110 switch, which is very similar except for the fact it has more than 5 ports. So we need to replace the hardcoded SJA1105_NUM_PORTS in this driver with ds->num_ports. This patch is as mechanical as possible (save for the fact that ds->num_ports is not an integer constant expression). Signed-off-by:

Currently, when host set VF untrusted, the driver will disable the promisc mode of VF. It may be conflicted when the VF requests the host to set promisc mode. So refactor it by changing promisc mode for VF asynchronously. With this change, the promisc mode of VF can be restored when the VF being trusted again. Signed-off-by:
