Since the commit b0ca2a21 ("sh_eth: Add support of SH7763 to sh_eth") the *enum* declaring the EESIPR bits (interrupt mask) went out of sync with the *enum* declaring the EESR bits (interrupt status) WRT bit naming and formatting. I'd like to restore the consistency by using EESIPR as the bit name prefix, renaming the *enum* to EESIPR_BIT, and (finally) renaming the bits according to the available Renesas SH77{34|63} manuals; additionally, reconstruct couple names using the EESR bit declaration above...

Gregory CLEMENT says: ==================== dsa: Add support for the ethernet switch on the ESPRESSObin This set of patches adds support for the Marvell Ethernet Topaz switch family (88E6141/88E6341) which is found on the ESPRESSObin. With this series the network is usable on this board. As usual, I rebased the series on the very last net-next/master. In this series there is no temperature support which need some patches form Andrew Lunn. As soon as Andrew Lunn will post the needed patch I will send a patch to enable the temperature support. Changelog: v6 -> v7: - rebased on net-next/master (5b8784aa) - Fixed the wrong age time coeff from 15s to 3.75s. - Remove support for temperature sensor v5 -> v6: - rebased on net-next/master (d140199a) - Fix the redundant check on mv88e6xxx_6341_family (reported by Julia Lawall) - Add support for the 88E6141 - Move support for temperature sensor in the phy part ==================== Signed-off-by:

The Marvell 88E6341 device is single-chip, 6-port Ethernet switch with four integrated 10/100/1000Mbps Ethernet transceivers and one high speed SerDes interfaces. It belongs to the Topaz family and unlike the 88E6341 it does not have a TCAM. Signed-off-by:

The Marvell 88E6341 device is single-chip, 6-port Ethernet switch with four integrated 10/100/1000Mbps Ethernet transceivers and one high speed SerDes interfaces. It is partially compatible with switches of family 88E6352 and switches of family 88E6390. This commit adds an initial support for this switch by describing its capabilities to the driver and introducing a new family. Signed-off-by:

Some Marvell ethernet switches have internal ethernet transceivers with hardcoded phy addresses. These addresses can be greater than the number of ports or its value might be different than the associated port number. This is for example the case for MV88E6341 that has 6 ports and internal Port 1 to Port4 PHYs mapped at SMI addresses from 0x11 to 0x14. This commits fixes the issue by removing the condition in MDIO callbacks. Signed-off-by:

Add necessary plumbing at the slave network device level to have switch drivers implement ndo_setup_tc() and most particularly the cls_matchall classifier. We add support for two switch operations: port_add_mirror and port_del_mirror() which configure, on a per-port basis the mirror parameters requested from the cls_matchall classifier. Code is largely borrowed from the Mellanox Spectrum switch driver. Reviewed-by:

Packets arriving in a VRF currently are delivered to UDP sockets that aren't bound to any interface. TCP defaults to not delivering packets arriving in a VRF to unbound sockets. IP route lookup and socket transmit both assume that unbound means using the default table and UDP applications that haven't been changed to be aware of VRFs may not function correctly in this case since they may not be able to handle overlapping IP address ranges, or be able to send packets back to the original sender if required. So add a sysctl, udp_l3mdev_accept, to control this behaviour with it being analgous to the existing tcp_l3mdev_accept, namely to allow a process to have a VRF-global listen socket. Have this default to off as this is the behaviour that users will expect, given that there is no explicit mechanism to set unmodified VRF-unaware application into a default VRF. Signed-off-by:

Florian Fainelli says: ==================== net: dsa: bcm_sf2: CFP support This patch series adds support for the Broadcom Compact Field Processor (CFP) which is a classification and matching engine built into most Broadcom switches. We support that using ethtool::rxnfc because it allows all known uses cases from the users I support to work, and more importantly, it allows the selection of a target rule index, which is later used by e.g: offloading hardware, this is an essential feature that I could not find being supported with cls_* for instance.

Currently the retransmission stats are not incremented if the retransmit fails locally. But we always increment the other packet counters that track total packet/bytes sent. Awkwardly while we don't count these failed retransmits in RETRANSSEGS, we do count them in FAILEDRETRANS. If the qdisc is dropping many packets this could under-estimate TCP retransmission rate substantially from both SNMP or per-socket TCP_INFO stats. This patch changes this by always incrementing retransmission stats on retransmission attempts and failures. Another motivation is to properly track retransmists in SCM_TIMESTAMPING_OPT_STATS. Since SCM_TSTAMP_SCHED collection is triggered in tcp_transmit_skb(), If tp->total_retrans is incremented after the function, we'll always mis-count by the amount of the latest retransmission.

Add two stats in SCM_TIMESTAMPING_OPT_STATS: TCP_NLA_DATA_SEGS_OUT: total data packets sent including retransmission TCP_NLA_TOTAL_RETRANS: total data packets retransmitted The names are picked to be consistent with corresponding fields in TCP_INFO. This allows applications that are using the timestamping API to measure latency stats to also retrive retransmission rate of application write. Signed-off-by:

Timur Tabi says: ==================== net: qcom/emac: Although not related, these patches affect the same files, so they should be applied in order. The first patch cleans up logging of when the the phy driver is attached. The second patch always configures the SGMII to use autonegotiation mode. The third patch removes a redundant call to emac_mac_start(). The fourth patch removes some extraneous non-functioning WOL code. The fifth patch adds an error handler for the SGMII block. ==================== Signed-off-by: -
Timur Tabi authored
The SGMII (internal PHY) can report decode errors via an interrupt. It can also report autonegotiation status changes, but we don't need to track those. The SGMII can recover automatically from most decode errors, so we only reset the interface if we get multiple consecutive errors. It's possible for bogus decode errors to be reported while the link is being brought up. The interrupt is registered when the interface is opened, and it's enabled after the link is up.

Regardless of how the external PHY is configured, the internal PHY (the "SGMII" block) is capable of configuring the SGMII link automatically. When the external PHY link comes up, regardless of how it is configured, the SGMII link is configured automatically. Signed-off-by:

Timur Tabi authored
The PHY driver is attached only when the driver calls phy_connect_direct(). Calling phy_attached_print() to display information about the PHY driver prior to that point is meaningless. The interface can be brought down, a new PHY driver can be loaded, and the interface then brought back up. This is the correct time to display information about the attached driver. Since phy_attached_print() also prints information about the interrupt, that needs to be set as well. Signed-off-by:
