* net: ethernet: fix similar warning reported by kbuild test robotPetr Štetiar2019-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes following (similar) warning reported by kbuild test robot: In function ‘memcpy’, inlined from ‘smsc75xx_init_mac_address’ at drivers/net/usb/smsc75xx.c:778:3, inlined from ‘smsc75xx_bind’ at drivers/net/usb/smsc75xx.c:1501:2: ./include/linux/string.h:355:9: warning: argument 2 null where non-null expected [-Wnonnull] return __builtin_memcpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/usb/smsc75xx.c: In function ‘smsc75xx_bind’: ./include/linux/string.h:355:9: note: in a call to built-in function ‘__builtin_memcpy’ I've replaced the offending memcpy with ether_addr_copy, because I'm 100% sure, that of_get_mac_address can't return NULL as it returns valid pointer or ERR_PTR encoded value, nothing else. I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this would make the warning disappear also, but it would be confusing to check for impossible return value just to make a compiler happy. I'm now changing all occurencies of memcpy to ether_addr_copy after the of_get_mac_address call, as it's very likely, that we're going to get similar reports from kbuild test robot in the future.

* net: ethernet: support of_get_mac_address new ERR_PTR errorPetr Štetiar2019-05-072-2/+2
| | | | | | | | | | | | | | There was NVMEM support added to of_get_mac_address, so it could now return ERR_PTR encoded error values, so we need to adjust all current users of of_get_mac_address to this new fact. While at it, remove superfluous is_valid_ether_addr as the MAC address returned from of_get_mac_address is always valid and checked by is_valid_ether_addr anyway.

| | | | | | | | | | | | | | | | | | | The Davinci MDIO in most of the case implemented as module inside of TI CPSW subsystem and fully depends on CPSW to be enabled, but historically it's implemented as separate Platform device/driver and defined in DT files in two ways: - as standalone node - as child node of CPSW subsystem. In later case it's required to split CPSW subsystem "reg" property to exclude MDIO I/O range which is not useful. Hence, replace devm_ioremap_resource() with devm_ioremap() to allow define full I/O range in parent CPSW subsystem without spliting.

| | | | | | | | | | | | | | | Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is working in non dual_mac mode, but in dual_mac - it causes enabling/disabling ALLMULTI flag for both ports. Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to specify ALE port number for which ALLMULTI has to be enabled and check if port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.

This removes direct access to the node name pointer. For instances using of_node_cmp, this has the side effect of now using case sensitive comparisons.

* | net: ethernet: ti: cpts: move enable/disable flags outside of cpts moduleIvan Khoronzhuk2018-11-144-77/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each slave has it's own receive timestamp filter. But cpts rx/tx timestamp enable flags are used to allow ts retrieve only for one user. This limitation causes data path redundancy and setting overlap if cpsw module is in dual-mac mode for instance. If rx ts is enabled only for one port - the second interface must expect every incoming packet to be PTP packet w/o absolutely any reason, and if it's PTP - do unneeded stuff, as rx filter for second port is not set and cpts fifo is not supposed to contain appropriate ts event. That's not correct. So, to fix control overlap and avoid redundant CPU cycles, the patch splits rx/tx ts enable flags between network devices. After the patch, PTP timestamping still should be used for only one port (or PTP id counter has to be different for both ports as cpts IP is common).

| | | | | | | | | | | | | | | | | | | | | | | | | | The overflow event is running with 1 jiffy in case if txq is not empty, but it can be emptied completely only if next tx event consumes skb or deletes staled skb from the txq. In case of staled skb, that can happen for some unpredictable reason (the ts event was lost or timed out), the overflow event can be generated quite long time consuming CPU w/o reason before next tx event happens. To avoid it, purge txq before increasing overflow event rate. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
