Add an input flag to flow dissector on rather dissection should be stopped when a flow label is encountered. Presumably, the flow label is derived from a sufficient hash of an inner transport packet so further dissection is not needed (that is ports are not included in the flow hash). Using the flow label instead of ports has the additional benefit that packet fragments should hash to same value as non-fragments for a flow (assuming that the same flow label is used). We set this flag by default in for skb_get_hash. Signed-off-by: NTom Herbert <tom@herbertland.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This wasn't a problem before because the phys were not children of the bus: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03 /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0 But now that they are: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03 when mdiobus_unregister deletes the bus device, the phy subdirs are removed from sysfs also. So when the phys are unregistered afterward, we get the warning. This patch changes the order so that phys are unregistered before the bus device is deleted.

Andrew Lunn says: ==================== DSA port configuration and status This patchset allows various switch port settings to be configured and port status to be sampled. Some of these patches have been posted before. The first three patches provide infrastructure for configuring a switch ports link speed and duplex from a fixed_link phy. Patch four then uses this infrastructure to allow the CPU and DSA ports of a switch to be configured using a fixed-link property in the device tree. Patches five and six allow a phy-mode property to be specified in the device tree, and allow this to be used for configuring RGMII delays. Patches seven through nine allow link status, for example that of an SFP module, to be read from a gpio.

What features a phy supports is masked in genphy_config_init() by looking at the PHYs BMSR register. If the link is down, fixed_phy_update_regs() will only set the auto- negotiation capable bit in BMSR. Thus genphy_config_init() comes to the conclusion the PHY can only perform 10/Half, and masks out the higher speed features. If however the link it up, BMSR is set to indicate the speed the PHY is capable of auto-negotiating, and genphy_config_init() does not mask out the high speed features. To fix this, when the link is down, have fixed_phy_update_regs() leave the link status, auto-negotiation complete, and link partner capabilities unset, but set all the local capabilities depending on the fixed phy speed.

The current code sets user ports to perform auto negotiation using the phy. CPU and DSA ports are configured to full duplex and maximum speed the switch supports. There are however use cases where the CPU has a slower port, and when user ports have SFP modules with fixed speed. In these cases, port settings to be read from a fixed_phy devices. The switch driver then needs to implement the adjust_link op, so the port settings can be set.

Some Ethernet MAC drivers using the PHY library require the hardcoding of link parameters when interfaced to a switch device, SFP module, switch to switch port, etc. This has typically lead to various ad-hoc implementations looking like this: - using a "fixed PHY" emulated device, which will provide link indication towards the Ethernet MAC driver and hardware - pretend there is no PHY and hardcode link parameters, ala mv643x_eth Based on that, it is desireable to have the PHY drivers advertise the correct link parameters, just like regular Ethernet PHYs towards their CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able to tell whether this link should be monitored or not. In the context of an Ethernet switch, SFP module, switch to switch link, we do not need to monitor this link since it should be always up.

Currently, the following case doesn't use DCTCP, even if it should: A responder has f.e. Cubic as system wide default, but for a specific route to the initiating host, DCTCP is being set in RTAX_CC_ALGO. The initiating host then uses DCTCP as congestion control, but since the initiator sets ECT(0), tcp_ecn_create_request() doesn't set ecn_ok, and we have to fall back to Reno after 3WHS completes. We were thinking on how to solve this in a minimal, non-intrusive way without bloating tcp_ecn_create_request() needlessly: lets cache the CA ecn option flag in RTAX_FEATURES. In other words, when ECT(0) is set on the SYN packet, set ecn_ok=1 iff route RTAX_FEATURES contains the unexposed (internal-only) DST_FEATURE_ECN_CA. This allows to only do a single metric feature lookup inside tcp_ecn_create_request(). Joint work with Florian Westphal.
