* ramips: remove further mt7621 code from local ethernet driverAdrian Schmutzler2020-08-265-265/+2
| | | | | | | | | | | | | | | While commit 734a8c46e703 focussed on removing stuff directly selected by the NET_RALINK_* symbols, this patch removes additional unused mt7621-specific code from the ethernet driver. As with the previous patch, the main reason is to reduce the amount of code we have to maintain and care about. Note that this patch still keeps a few lines with IS_ENABLED(CONFIG_SOC_MT7621) in mtk_eth_soc.h/.c, as this file is still selected for the mt7621 subtarget.

* ramips: remove legacy ethernet driver components for mt7621Adrian Schmutzler2020-08-218-1433/+6
| | | | | | | | | | | | | | | | The mt7621 subtarget has been switched to DSA quite a while ago and seems to run sufficiently fine. Build with older kernels than 5.4 has been disabled directly during the kernel bump, so our local ethernet driver is unused in master since then. Therefore, let's remove the mt7621-specific parts of "our" ethernet driver, so we don't have to maintain them and it's obvious to everybody that they are not used anymore. This also drops the offloading components as this was specifically implemented to depend on mt7621. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ramips: fix sd pollingQin Wei2020-06-271-0/+4
| | | | | | | | | | This is fixed in 18.06, it appears again in 19.07. Currently mt7628 sdcard driver do not support polling mode which is for the device do not have card-detect pin to detect sd card insert. Without this patch, device will not detect sdcard is inserted. This patch is a fix of that. Signed-off-by: Qin Wei <support@vocore.io>

* ramips: Enable rx of 1536 bytes ethernet frames on MT7621John Crispin2015-10-051-4/+4
| | | | | | | | | | | The default switch frame size (with FCS + header) is 1536 bytes. But the GMAC only accepted frames up to 1522 bytes. Setting it to 1536 allows to receive ethernet frames using the full of MTU 1500 + an extra VLAN header + VLAN header added by the switch.

* ramips: Fix too small rx bufferJohn Crispin2015-10-051-4/+12
| | | | | | | | | | | | | | | | | | The driver assumes that the maximum received buffer for non-jumbo frames is 1536 bytes. But the allocation of the rx fragment doesn't reflect that. It currently allocates fragments which will only be large enough to be used as rx buffer with the size of 1534 bytes. This is problematic because the GMAC will now try to write to 2 bytes which don't belong to its receive buffer when a large enough ethernet frame is received. This may already be a problem on existing chips but will at least become a problem when the 1536 byte rx modus is enabled on MT7621a. It is required on this SoC to receive ethernet frames which use their full 1500 bytes MTU and a VLAN header next to the switch VLAN tag.

* ramips: Fix setting of rx buffer lengthJohn Crispin2015-10-052-2/+3
| | | | | | | | | | | | | | The length of the DMA rx buffer was always set to 0 because the function for extracting the length was used to calculate the value for setting it. Instead the macro has to be split in a get and set function similar to the TX_DMA_(GET_|)PLEN(0|1) macro. No problem was noticed on MT7621a before this was changed and thus maybe it was hidden by different problem which is not yet fixed.

* ramips: Allow to receive vlan over untag ports on MT7530John Crispin2015-10-051-3/+33
| | | | | | | | | | | | | | | | | | | | The MT7530 switch driver with enable_vlan set will automatically set all ports to the user port mode. The hardware will remove the incoming vlan tag on these ports and use it for its internal vlan. This is usually not wanted and makes it impossible to communicate via vlan over the switch in both directions. It is possible to configure a switch port to "transparent mode" when this port is only used as untag in the switch VLANs. This will disable the VLAN untagging of packets when they were received on this port. The tagging on "tag" ports based on the vlan id is still working. The transparent port mode cannot be used when a port is both used in a VLAN as "tag" and in another one as "untag" port. Signed-off-by: Sven Eckelmann <sven@open-mesh.com> SVN-Revision: 47114
