* realtek: Add L2 hash bucket sizeBirger Koblitz2021-05-072-3/+5
| | | | | | | | Adds a hash-bucket size attribute for the different SoCs, in order to accomodate the buckets with 8 entries of the L2-forwarding tables on RTL93XX in contrast to only 4 on RTL83XX. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>

| | | | | | remove fdb_dump debugging function Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: add IGMP/MLD snooping supportBirger Koblitz2021-05-072-4/+7
| | | | | | | This adds snooping support for IGMP and MLD on RTL8380/90/9300 by trapping IGMP and MLD packets to the CPU. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: enable CRC offloadingBirger Koblitz2021-05-071-24/+93
| | | | | | | | | | Enables CRC calculation offloading on RTL8380/8390/9300. Tested on Zyxel XGS1210-10 (RTL9302)/GS1900-48 (RTL8390)/GS1900-10HP (RTL8382) On the Zyxel GS1900-10HP, an increase of 5% in iperf3 send throughput and 11% in receive throughput is seen.

* realtek: enable SerDes NWAY and SGMII negotiationBjørn Mork2021-03-172-3/+42
| | | | | | | This allows copper SFPs to negotiate speeds lower than 1gig. Acked-by: Birger Koblitz <mail@birger-koblitz.de> Signed-off-by: Bjørn Mork <bjorn@mork.no>
* realtek: need to handle PHY_INTERFACE_MODE_NA for sfpsBjørn Mork2021-03-171-0/+1
| | | | | | | | | | From the validate docs in include/linux/phylink.h: When state->interface is PHY_INTERFACE_MODE_NA, phylink expects the MAC driver to return all supported link modes. Tested-by: Birger Koblitz <mail@birger-koblitz.de> Signed-off-by: Bjørn Mork <bjorn@mork.no>
* realtek: fix link-state interruptBjørn Mork2021-03-171-4/+3
| | | | | | | This bug was the root cause for the failing sfp driver. Acked-by: Birger Koblitz <mail@birger-koblitz.de> Signed-off-by: Bjørn Mork <bjorn@mork.no>
* realtek: drop ethtool log noiseBjørn Mork2021-03-122-15/+15
| | | | | | | | | | | | | Demote a number of debugging printk's to pr_debug to avoid log nosie. Several of these functions are called as a result of userspace activity. This can cause a lot of log noise when userspace does periodic polling. Most of this could probably be removed completely, but let's keep it for now since these drivers are still in development.

* realtek: add debugfs support for mirroringBirger Koblitz2021-01-261-14/+391
| | | | | | This adds debugfs support to monitor mirroring via debugfs Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: add API for the hw tables of RTL83XX/93XX SoCsBirger Koblitz2021-01-261-100/+436
| | | | | | | | Add a table API that has per accss register locking and uses register description information to handle all table access through a single set of api calls. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: add switch driver support for the RTL93XX based switchesBirger Koblitz2021-01-265-245/+1522
| | | | | | | Adds support for the RTL9300 and RTL9310 series of switches with 10GBit per port and up to 56 ports. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: add internal and external SDS/PHYs of RTL9300 devicesBirger Koblitz2021-01-262-28/+523

* realtek: Add missing case in switch statementRafał Mikrut2020-12-111-0/+1
| | | | | | | | | | | | Cppcheck shows here duplicated break. Code `state->speed = SPEED_1000;` will be never executed because above it there is break statement. Almost identical statement is placed in another realtek driver https://github.com/openwrt/openwrt/blob/18a53d43d646290053eff4736ec852efcf6bf510/target/linux/realtek/files-5.4/drivers/net/dsa/rtl83xx/dsa.c#L286-L294 Signed-off-by: Rafał Mikrut <mikrutrafal@protonmail.com>
* realtek: Fix self assignmentRafał Mikrut2020-12-111-1/+1
| | | | | | | | | Cppcheck shows self initialization error, which is an obvious bug. Basing on logic of similar fragment below I assigned to this variable, value `RTL838X_LED_GLB_CTRL` which I think is proper. Signed-off-by: Rafał Mikrut <mikrutrafal@protonmail.com>
