| * | net: ethernet: ti: cpsw_ale: use const for API having pointer on mac address | Ivan Khoronzhuk | 2018-10-15 | 1 | -6/+6 |
| | | | | | | | | | It allows to use function under callbacks with same const qualifier of mac address for farther changes. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net> | ||||
| * | net: ethernet: ti: cpsw: clear all entries when delete vid | Ivan Khoronzhuk | 2018-08-11 | 1 | -1/+1 |
| | | | | | | | | | | | | In cases if some of the entries were not found in forwarding table while killing vlan, the rest not needed entries still left in the table. No need to stop, as entry was deleted anyway. So fix this by returning error only after all was cleaned. To implement this, return -ENOENT in cpsw_ale_del_mcast() as it's supposed to be.

| | | | | | | | | | | Move static initialization from cpsw_ale_start() to cpsw_ale_create() as it does not make much sence to perform static initializtion in cpsw_ale_start() which is called everytime netif[s] is opened.

| | | | | | | | | | | | The ale->params.ale_ports parameter can be used to deriver values for all ale entry mask bits: port_mask_bits, port_mask_bits, port_num_bits. Hence, calculate above values and drop all hardcoded values. For port_num_bits calcualtion use order_base_2() API. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

| | | | | | | | | | | | ALE is enabled from cpsw_ale_start() now, but disabled only from cpsw_ale_destroy() which introduces inconsitance as cpsw_ale_start() is called when netif[s] is opened, but cpsw_ale_destroy() is called when driver is removed. Hence, move ALE disabling in cpsw_ale_stop(). Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net> | ||||

These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

| * | net: netcp: ale: add proper ale entry mask bits for netcp switch ALE | Karicheri, Muralidharan | 2017-01-07 | 1 | -19/+80 |
| | | | | | | | | | | | | | | | For NetCP NU Switch ALE, some of the mask bits are different than defaults used in the driver. Add a new macro DEFINE_ALE_FIELD1 that use a configurable mask bits and use it in the driver. These bits are set to correct values by using the new variables added to cpsw_ale structure and re-used in the macros. The parameter nu_switch_ale is configured by the caller driver to indicate the ALE is for that switch and is used in the ALE driver to do customization as needed.

| * | net: netcp: ale: use ale_status to size the ale table | Karicheri, Muralidharan | 2017-01-07 | 1 | -1/+30 |
| | | | | | | | | | | | | | | | | | | ALE h/w on newer version of NetCP (K2E/L/G) does provide a ALE_STATUS register for the size of the ALE Table implemented in h/w. Currently for example we set ALE Table size to 1024 for NetCP ALE on K2E even though the ALE Status/Documentation shows it has 8192 entries. So take advantage of this register to read the size of ALE table supported and use that value in the driver for the newer version of NetCP ALE. For NetCP lite, ALE Table size is much less (64) and indicated by a size of zero in ALE_STATUS. So use that as a default for now. While at it, also fix the ale table size on 10G switch to 2048 per User guide http://www.ti.com/lit/ug/spruhj5/spruhj5.pdf Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: David S.

| * | net: netcp: ale: update to support unknown vlan controls for NU switch | Karicheri, Muralidharan | 2017-01-07 | 1 | -5/+45 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | In NU Ethernet switch used on some of the Keystone SoCs, there is separate UNKNOWNVLAN register for membership, unreg mcast flood, reg mcast flood and force untag egress bits in ALE. So control for these fields require different address offset, shift and size of field. As this ALE has the same version number as ALE in CPSW found on other SoCs, customization based on version number is not possible. So use a configuration parameter, nu_switch_ale, to identify the ALE ALE found in NU Switch. Different treatment is needed for NU Switch ALE due to difference in the ale table bits, separate unknown vlan registers etc. The register information available in ale_controls, needs to be updated to support the netcp NU switch h/w. So it is not constant array any more since it needs to be updated based on ALE type. The header of the file is also updated to indicate it supports N port switch ALE, not just 3 port. The version mask is 3 bits in NU Switch ALE vs 8 bits on other ALE types. While at it, change the debug print to info print so that ALE version gets displayed in boot log.

| * | drivers: net: cpsw: make cpsw_ale.c a module to allow re-use on Keystone | Karicheri, Muralidharan | 2015-01-31 | 1 | -2/+24 |
| | | | | | | | | | | | | | | | | | | | | | | NetCP on Keystone has cpsw ale function similar to other TI SoCs and this driver is re-used. To allow both ti cpsw and keystone netcp to re-use the driver, convert the cpsw ale to a module and configure it through Kconfig option CONFIG_TI_CPSW_ALE. Currently it is statically linked to both TI CPSW and NetCP and this causes issues when the above drivers are built as dynamic modules. This patch addresses this issue While at it, fix the Makefile and code to build both netcp_core and netcp_ethss as dynamic modules. This is needed to support arm allmodconfig. This also requires exporting of API calls provided by netcp_core so that both the above can be dynamic modules.

| * | drivers: net: cpsw: Support ALLMULTI and fix IFF_PROMISC in switch mode | Lennart Sorensen | 2014-10-31 | 1 | -0/+29 |
| | | | | | | | | | | | | | | | | | | | | The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic multicast routing not work. Related to this, when enabling IFF_PROMISC in switch mode, all registered multicast addresses are flushed, resulting in only broadcast and unicast traffic being received. A new cpsw_ale_set_allmulti function now scans through the ALE entry table and adds/removes the host port from the unregistered multicast port mask of each vlan entry depending on the state of IFF_ALLMULTI. In promiscious mode, cpsw_ale_set_allmulti is used to force reception of all multicast traffic in addition to the unicast and broadcast traffic. With this change dynamic multicast and promiscious mode both work in switch mode. Signed-off-by: Len Sorensen <lsorense@csclub.uwaterloo.ca> Signed-off-by: David S.
