* ramips: mt7530: remove redundant global attrs for port mirroringYousong Zhou2020-03-031-88/+0
| | | | | | | | | | | | | | | | | | | | Global attributes enable_mirror_tx/enable_mirror_rx depend on runtime value of another global attribute mirror_source_port which just resides in the memory The same functionality can be achieved by directly setting port attribute of the same names. E.g. the following two groups of commands achieve the same thing swconfig dev switch0 set mirror_source_port 3 swconfig dev switch0 set enable_mirror_tx 1 swconfig dev switch0 set mirror_source_port 4 swconfig dev switch0 set enable_mirror_tx 1 swconfig dev switch0 port 3 set enable_mirror_tx 1 swconfig dev switch0 port 4 set enable_mirror_tx 1 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
* ramips: gsw_mt7621: disable PORT 5 MAC RX/TX flow control by defaultPetr Štetiar2020-02-201-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | Looking at the current upstream driver implementation, it seems like the TX/RX flow control is enabled only if the flow control pause option is resolved from the device/link partner advertisements (or otherwise set). On the other hand, our current in-tree driver force enables TX/RX flow control by default, thus possibly leading to TX timeouts if the other end sends pause frames (which are not properly handled?): WARNING: CPU: 3 PID: 0 at net/sched/sch_generic.c:320 dev_watchdog+0x1ac/0x324 NETDEV WATCHDOG: eth0 (mtk_soc_eth): transmit queue 0 timed out Disabling the flow control on PORT 5 MAC seems to fix this issues as the pause frames are then filtered out. While at it, I'm removing the if condition completely as suggested, since this code is run only on mt7621 SoC, so there is no need to check for the silicon revisions.

* ramips: mt7620: fix external PHY autopollingPawel Dembicki2019-06-201-4/+6
| | | | | | | | | | | | | | | | | The port initialisation is based on assumption that phy address and port number is the same. SoC allow different numbers and some board have it. Use phy address instead the port number to make sure that correct addresses are polled. In situation when only one PHY with address 0x0 is conected to port 4, autopolling is broken. This patch make autopolling correct when port number and phy address are different. Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com>
* ramips: handle mdio address and switch port seperateMathias Kresin2019-06-204-11/+14
| | | | | | | | | | | | | | | The phy handling code forces a phy mdio address and the switch port to which a phy is attached to be the same. Albeit such a configuration is used for most boards, it isn't for all. Pass the switch port number to the ethernet phy connect functions, to ensure the correct list entry is edited and not the list entry that matches th phys mdio address. Use the mdio address with mdiobus_get_phy instead of the port number, to make sure the expected ethernet phy gets connected. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: ignore already handled ethernet physMathias Kresin2019-06-201-2/+8
| | | | | | | | | | | | The whole logic in fe_phy_connect() is based on the asumption that mdio address and switch port id are equal. Albeit it is true for most boards, it doesn't is for all. It isn't yet clear which subtargets/boards require the devicetree less ethernet phy handling. Hence change the code in a way that it doesn't touch ethernet phys which were early attached and are already handled. Signed-off-by: Mathias Kresin <dev@kresin.me>

* ramips: fix two-way hash and auto ageout on MT7621HsiuWen Yen2019-01-231-17/+18
| | | | | | | | | | | | | | | | | | | | | | | | Current code directly writes the FOE entry to hash_val+1 position when hash collision occurs. However, it is found that this behavior will cause the cache and the hardware FOE table to be inconsistent. For example, there are three flows, and their hashed values are all equal to 100. The first flow is written to the position of 100. The second flow is written to the position of 100+1. Then, the logic of the current code will also write the third flow to 100+1. At this time, the cache has flow 1 and 2; and the hardware FOE table has flow 1 and 3, where these two parts store different contents. So it is necessary to check whether the hash_val+1 is also occupied before writing. If hash_val+1 is also occupied, we won’t bind th third flow to the FOE table. Addition to that, we also cancel the processing of foe_entry removal because the hardware has auto age-out ability. The hardware will periodically iterate through the FOE table to find out the time-out entry and set it as INVALID. Signed-off-by: HsiuWen Yen <y.hsiuwen@gmail.com>

| | | | | | | | | | Sometimes the tuples might be hashed to the same FOE entry. When this hash collision problem occurs, some of the connections will not be bound and consequently the CPU idle rate cannot reach 100%. Therefore, two-way hashing is adopted to alleviate this problem. Signed-off-by: HsiuWen Yen <y.hsiuwen@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | To share mdio addr for IntPHY and ExtPHY, as described in the documentation (MT7620_ProgrammingGuide.pdf). (refer: http://download.villagetelco.org/hardware/MT7620/MT7620_ProgrammingGuide.pdf) when port4 setup to work as gmac mode, dts like: &gsw { mediatek,port4 = "gmac"; }; we should set SYSCFG1.GE2_MODE==0x0 (RGMII). but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default so we need to re-set it to 0x0 before this changes: gsw: 4FE + 2GE may not work correctly and MDIO addr 4 cannot be used by ExtPHY after this changes: gsw: 4FE + 2GE works and MDIO addr 4 can be used by ExtPHY Signed-off-by: Chen Minqiang <ptpt52@gmail.com>
* ramips: fix gigabit switch PHY access on MDIODaniel Gimpelevich2018-08-061-1/+2
| | | | | | | | | | When PHY's are defined on the MDIO bus in the DTS, gigabit support was being masked out for no apparent reason, pegging all such ports to 10/100. If gigabit support must be disabled for some reason, there should be a "max-speed" property in the DTS.

* ramips: remove superfluous & confusing DT bindingDaniel Gimpelevich2018-08-061-3/+24
| | | | | | | | | | | Mediatek has a reference platform that pairs an MT7620A with an MT7530W, where the latter responds on MDIO address 0x1f while both chips respond on 0x0 to 0x4. The driver special-cases this arrangement to make sure it's talking to the right chip, but two different ways in two different places. This patch consolidates the detection without the current requirement of both tests to be separately satisfied in the DTS. Signed-off-by: Daniel Gimpelevich <daniel@gimpelevich.san-francisco.ca.us>

* ramips: ethernet: use own page_frag_cacheFelix Fietkau2018-07-122-3/+15
| | | | | | | | | | | | | | | | Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragment. This can happen if the ethernet driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments, which only happens after the rings of all drivers holding the fragments have wrapped around. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak Signed-off-by: Felix Fietkau <nbd@nbd.name>
