2016-11-28net: phy: realtek: fix enabling of the TX-delay for RTL8211FMartin Blumenstingl1-8/+12
The old logic always enabled the TX-delay when the phy-mode was set to PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the PHY driver to enable the RX and/or TX delays: - PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the PHY (if required, the MAC should add the delays in this case) - PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY (currently not supported by RTL8211F) With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID and PHY_INTERFACE_MODE_RGMII_TXID. Additionally we now explicity disable the TX-delay, which seems to be enabled automatically after a hard-reset of the PHY (by triggering it's reset pin) to get a consistent state (as defined by the phy-mode). This fixes a compatibility problem with some SoCs where the TX-delay was also added by the MAC. With the TX-delay being applied twice the TX clock was off and TX traffic was broken or very slow (<10Mbit/s) on 1000Mbit/s links.

2016-11-27ptp: gianfar: Use high resolution frequency method.Ulrik De Bie1-8/+13
This patch depends on commit d8d263541913 ("ptp: Introduce a high resolution frequency adjustment method.") The gianfar devices offer a frequency resolution of about 0.46 ppb (depends on actual value of tmr_add, for the calculation assumed 0x80000000). This patch lets users of the device benefit from the increased frequency resolution when tuning the clock. Thanks to the rounding the maximum error between the requested frequency and the applied frequency will then be about 0.23 ppb. Tested on a v3.3.8 kernel on a real gianfar device. Verified compilation on net-next (currently at v4.9-rc5). Signed-off-by: Ulrik De Bie <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2016-11-25mlxsw: spectrum: Add policers for trap groupsNogah Frankel1-2/+72
Configure policers and connect them to trap groups. While many trap groups share policer's configuration they don't share the actual policer because each trap group represents a different flow / protocol and we don't want one of them to be able to exceed its rate on behalf of another. For example, if STP and LLDP gets to send 128 packets/sec each, if we put them in one 256 packets/sec policer, one can send 200 packets while the other only 50. Note that IP2ME covers lots of flows, so it's limit is set to match the cpu ability to handle data.

2016-11-25mlxsw: Create a different trap group list for each deviceNogah Frankel3-34/+77
Trap groups can be used to control traps priority, both in terms of which trap "wins" if a packet matches two traps (priority) and in terms of packets from which trap group will be scheduled to the cpu first (tc). They can also be used to set rate limiters (policers) on them (will be added in the next patches). Currently, we support two trap groups. In Spectrum we want a better resolution, so every protocol / flow will have a different trap group, so we can control its parameters separately. Once the policers will be implemented, it will also allow us limit the rate of each protocol by itself. This patch change the trap group list to include: * the emad trap group, which is shared for all the devices. * Switchx2's trap groups, which are a copy of the current trap groups. * Spectrum's new trap groups, in order to match the above guidelines. (Switchib is using only the emad trap group, so it require no changes). This patch also includes new configuration for Spectrum's trap groups, with primary priority order within them.

2016-11-25mlxsw: Change trap groups settingNogah Frankel4-40/+92
Trap groups have many options which we currently set to default values. In the next patches we will use many of them with non-default values. Some of these options have no default value, so this patch sets them as params for the trap group set function. Others almost always use the same values, so the set function will use this default values. In the rare cases when they will need to be with other values, these values can be set directly (using the macros for fields in registers). Parameters without default value: TC - the traffic class for packets that hit this trap group. (old default is the max tc) priority - if one packet hits multiple trap groups, the group with the higher priority will "catch" it. (old default is 0) policer - limit rate policer (old default is disabled) Default parameters: swid - switch id, relevant for the emad trap only, ignored on Spectrum. (new default is 0) rdq - CPU receive descriptor queue (new default is identical to trap group id) Signed-off-by: Nogah Frankel <[email protected]> Signed-off-by: Jiri Pirko <[email protected]> Signed-off-by: David S.
