Setting the speed independently of duplex makes little sense; the two parameters result from negotiation or fixed setup, and may have inter- dependencies. Moreover, they are always controlled via the same register - having them split means we have to read-modify-write this register twice. Combine the two operations into a single port_set_speed_duplex() operation. Not only is this more efficient, it reduces the size of the code as well. Signed-off-by:

phylink_mac_change() is supposed to be called with a 'false' argument if the link has gone down since it was last reported up; this is to ensure that link events along with renegotiation events are always correctly reported to userspace. Read the BMSR once when we have an interrupt, and report the link latched status to phylink via phylink_mac_change(). phylink will deal automatically with re-reading the link state once it has processed the link-down event.

Extend the mv88e6xxx phylink implementation down to Serdes PHYs, which handle the PCS layer of such links. - Implement phylink PCS link state reading, so that we can provide ethtool with the linkmodes and link speed in the expected manner. Note: this will only be called for in-band negotiation, which is only supported by the serdes interfaces. - Implement phylink PCS configuration, so that the in-band AN and advertisement can be configured. - Implement phylink PCS negotiation restart, so that the in-band AN can be restarted. - Implement phylink PCS link up, so that when operating out-of-band, the Serdes can be configured for the appropriate fixed speed mode.

The SGMII/1000base-X serdes register set is a clause 22 register set offset at 0x2000 in the PHYXS device. Rather than inventing our own defintions, use those that already exist, and name the register MV88E6390_SGMII_BMCR. Also remove the unused MV88E6390_SGMII_STATUS definitions. Signed-off-by:

Russell King says: ==================== net: mii clause 37 helpers This is a re-post of two patches that are common to two series that I've sent in recent weeks; I'm re-posting them separately in the hope that they can be merged. No changes from either of the previous postings. These patches: 1. convert the existing (unused) mii_lpa_to_ethtool_lpa_x() function to a linkmode variant. 2. add a helper for clause 37 advertisements, supporting both the 1000baseX and defacto 2500baseX variants. Note that ethtool does not support half duplex for either of these, and we make no effort to do so. ==================== Signed-off-by: -

The above makes mptcp_accept() quite complex, and requires checks is several places for NULL MPTCP master socket. These series simplify the MPTCP accept implementation, moving the master socket allocation at syn-ack time, so that we drop unneeded checks with the follow-up patch. v1 -> v2: - rebased on top of 2398e399 ==================== Signed-off-by:

This change moves the mptcp socket allocation from mptcp_accept() to subflow_syn_recv_sock(), so that subflow->conn is now always set for the non fallback scenario. It allows cleaning up a bit mptcp_accept() reducing the additional locking and will allow fourther cleanup in the next patch. Signed-off-by:

Antoine Tenart says: ==================== net: phy: split the mscc driver This is a proposal to split the MSCC PHY driver, as its code base grew a lot lately (it's already 3800+ lines). It also supports features requiring a lot of code (MACsec), which would gain in being split from the driver core, for readability and maintenance. This is also done as other features should be coming later, which will also need lots of code addition. This series shouldn't change the way the driver works. I checked, and there were no patch pending on this driver. This change was done on top of all the modifications done on this driver in net-next. Since v2: - Defined inline functions as static inline. - Fixed a locking issue reported by Kbuild. Since v1: - Moved more definitions into the mscc_macsec.h header. ==================== Signed-off-by: -

This patch splits the MSCC driver into separate files, per functionality, to improve readability and maintenance as the codebase grew a lot. The MACsec code is moved to a dedicated mscc_macsec.c file, the mscc.c file is renamed to mscc_main.c to keep the driver binary to be named mscc and common definition are put into a new mscc.h header. Most of the code was just moved around, except for a few exceptions: - Header inclusions were reworked to only keep what's needed. - Three helpers were created in the MACsec code, to avoid #ifdef's in the main C file: vsc8584_macsec_init, vsc8584_handle_macsec_interrupt and vsc8584_config_macsec_intr. The patch should not introduce any functional modification. Signed-off-by:

The MSCC PHY driver is growing, with lots of space consuming features (firmware support, full initialization, MACsec...). It's becoming hard to read and navigate in its source code. This patch moves the MSCC driver to its own directory, without modifying anything, as a preparation for splitting up its features into dedicated files. Signed-off-by:

Petr Machata says: ==================== RED: Introduce an ECN tail-dropping mode When the RED qdisc is currently configured to enable ECN, the RED algorithm is used to decide whether a certain SKB should be marked. If that SKB is not ECN-capable, it is early-dropped. It is also possible to keep all traffic in the queue, and just mark the ECN-capable subset of it, as appropriate under the RED algorithm. Some switches support this mode, and some installations make use of it. There is currently no way to put the RED qdiscs to this mode. Therefore this patchset adds a new RED flag, TC_RED_TAILDROP. When the qdisc is configured with this flag, non-ECT traffic is enqueued (and tail-dropped when the queue size is exhausted) instead of being early-dropped. Unfortunately, adding a new RED flag is not as simple as it sounds. RED flags are passed in tc_red_qopt.flags. However RED neglects to validate the flag field, and just copies it over wholesale to its internal structure, and later dumps it back. A broken userspace can therefore configure a RED qdisc with arbitrary unsupported flags, and later expect to see the flags on qdisc dump. The current ABI thus allows storage of 5 bits of custom data along with the qdisc instance. GRED, SFQ and CHOKE qdiscs are in the same situation. (GRED validates VQ flags, but not the flags for the main queue.) E.g. if SFQ ever needs to support TC_RED_ADAPTATIVE, it needs another way of doing it, and at the same time it needs to retain the possibility to store 6 bits of uninterpreted data. For RED, this problem is resolved in patch #2, which adds a new attribute, and a way to separate flags from userbits that can be reused by other qdiscs. The flag itself and related behavioral changes are added in patch To test the new feature, patch #1 first introduces a TDC testsuite that covers the existing RED flags. Patch #5 later extends it with taildrop coverage. Patch #6 contains a forwarding selftest for the offloaded datapath. To test the SW datapath, I took the mlxsw selftest and adapted it in mostly obvious ways. The test is stable enough to verify that RED, ECN and ECN taildrop actually work. However, I have no confidence in its portability to other people's machines or mildly different configurations. I therefore do not find it suitable for upstreaming. GRED and CHOKE can use the same method as RED if they ever need to support extra flags. SFQ uses the length of TCA_OPTIONS to dispatch on binary control structure version, and would therefore need a different approach. v2: - Patch #1 - Require nsPlugin in each RED test - Match end-of-line to catch cases of more flags reported than requested - Patch #2: - Replaced with another patch. - Patch #3: - Fix red_use_taildrop() condition in red_enqueue switch for probabilistic case. - Patch #5: - Require nsPlugin in each RED test - Match end-of-line to catch cases of more flags reported than requested - Add a test for creation of non-ECN taildrop, which should fail ==================== Signed-off-by: -

Extend RED testsuite to cover the new nodrop mode of RED-ECN. This test is really similar to ECN test, diverging only in the last step, where UDP traffic should go to backlog instead of being dropped. Thus extract a common helper, ecn_test_common(), make do_ecn_test() into a relatively simple wrapper, and add another one, do_ecn_nodrop_test(). Signed-off-by:
